Lesson from king David, weep for the living not dead. This means, while help maintaining Mr Faraday and family grave is good. It is better seek out and treat Mr Faraday's descendants to a drink or meal. Best is befriend to them.

I agree with your analysis. Maxwell established Mathematically that Faraday was correct all along when nobody believed him i.e.what Faraday was saying about electric and magnetic properties of light was correct
It rotated on its own. I developed the demo in the RI prep room. it rotates the same way anywhere in the building. Sulfuric acid has some bubbles that sometimes it needs a little push to get started, but it will continue to rotate for as long as we leave the power on.

Thank you, RI.
I truly loved this lecture. My entire career has involved innovation and prototyping, while I’m at a level far removed from Faraday, I’ve used many of the same methods to achieve my goals.

Thank you for the wonderful explanation I’ve been trying to put into words for decades.
To help power equipment in outer space: (copy and paste from my files): Potential endless energy source basically anywhere in this universe: a. Small aluminum cones with an electrical wire running through the center of the cones, cones spaced apart (not touching I'm thinking) but end to end. b. Electromagentic radiation energy in the atmosphere interacts with the aluminum cones. c. Jostled atoms and molecules in the cone eventually have some electrons try to get away from other electrons of which those electrons gather at the larger end of the cone, of which also creates an area of positive charge at the smaller end of the cone. d. The electron's in the wire are attracted to the positive end of the cone and the positive 'end' in the wire are attracted to the negatively charged end of the cone. e. Basically a 'battery' has been created inside the electrical wire itself, different areas of electrical potential. Basically a 'wire battery' or a 'batteryless battery', however one wanted to call it. f. Numerous cones placed end to end increases the number of 'batteries' in the wire. (In series to increase voltage, in parallel to increase amperage). * Via QED (Quantum Electro Dynamics) whereby electromagnetism interacts with electrons in atoms and molecules, one would have to find the correct 'em' frequency for the correct material being utilized for the cones. The shape of the cones could also come into play. The type and size of the wire as well as the type and thickness of the insulation between the cones and the wire would also be factors. * Of course also, possibly 2D triangles made up of certain materials with a conductor going down through the center of the triangle could possible achieve the same 'batteryless' battery system. * Plus possibly with the 2D concept, layered 2D's that absorb different energy frequencies, thereby increasing the net output.
To help protect against at least some harmful cosmic radiation: (copy and paste from my files): MODIFIED MOLECULES: More dense molecules with potentially new characteristics created primarily for potentially better protections from harmful cosmic radiation in outer space as well as different applications on planets and moons. Setup: a. A more complex molecule. b. It exists under: 1. A certain gravitational energy field. 2. Under certain electrical interactions. 3. Under certain magnetic interactions. 4. In a certain temperature. 5. In a certain pressure. Modification: a. Change 1 or more of the above items to change the shape of the molecule. Effects: (When modification item[s] removed): a. Molecule returns to it's original shape. b. Molecule returns to a shape larger than it's original shape. c. Molecule returns to a shape smaller than it's original shape. d. If larger than or smaller than it's original shape, then possibly the same molecule with different interacting characteristics, and if smaller than it's original shape, then a more dense molecule. e. Other atoms and/or molecules might be able to be attached to this 'new' material, and the 'new' larger molecule could possibly be modified as above yet again and on and on. The possibilities are virtually endless. f. New 'space age' material being formed for various uses.
@@charlesbrightman4237 Both of your proposed applications will require some imaginative and rigorous experimentation. Have you taken Faraday’s example and begun working on those experiments? Wouldn’t it be fun, and valuable, even if they didn’t quite do what you wanted?“Prototype” the results, contribute to future missions! Faraday would have!
It's beautiful to see those young men (probably, 8, 9 or 10 years) be introduced to electromagnetic induction at such a young age, more so the thought process and practical aspect that led to the motor we have today. Where I'm from, engineering students have to memorize Abomasum, and head, thorax and abdomen of a grasshopper.
"The Structure of Scientific Revolution" by T.S. Kuhns beautifully describes the paradigm shift. You see the world one way yet anomalies appear. To answer the reason for them you need to see it a different way and when you do; the world changes.
So very interested and entertaining. I spent 50 years in the electrical field and familiar with Faraday. I didn't know much about his early work. Thank you very much.
Visualizing magnetic fields was always confusing to me because of all the little windings in the DC motors I would play around with as a child. There's so much happening inside of the 'modern' motors. Great presentation! Peace
this was a nice discussion and demonstration. i worked with electricity my whole life, in my early days as a radio transmitter repairman in the u.s. air force and then as a lineman for a local municipal power company for 40+ years. i knew of faraday but mostly as a value of capacitance. it was a bit of a refresher on the early rudimentary basics of electricity. sometimes one forgets and then remembers about how much one has learned, known and experienced in life. thnx.
If everyone in the factories took as many safety precautions as you did for every slightly hazardous job.. nothing would ever get done. We are all fortunate that skilled labor takes the chances that they do.
And indeed -there was NO need for it!! - He isnt inviting members of the audience up to do anything contentious. As fa as I could see there was nothing more "dangerous" than a 9V pp3 battery !!
It almost sounds as though you are on the Board of such a company and thinking about cutting expenses at the risk of your employees? But if so, reconsider. Today’s skilled laborers have unprecedented access to legal recourse. And don’t put your comment in company correspondence - it will end up in some clever attorney’s brief and triple the punitive damages. lol. Of course, you may have a different reason for posting this. If you don’t mind, what is that reason? Respect, Jeff🙂
The techies also really should have adjusted his mic to stop us hearing his nasal breathing. Really distracting. And he skipped so much interesting detail - like he couldn’t wait to finish and go home; seemed impatient with his volunteers too.
Yes -such a shame. It isnt that difficult to produce decent demo equipment that gives predictable results. Especially when doing it for the RI !! Really was embarrassing to see him trying to get poorly produced demos to work - then giving half hearted apologies to his audience when they didn't work I think it was poorly planned, poorly rehearsed -and when it went wrong - he had nowhere to turn. ( apart from "turning the next slide2) And as for the disguised recording of "celebrating 200 years of the electric motor etc" - who the heck thought that was a good idea ??. A good lecture but I doubt if it did true justice to MF.
Great lecture and very interesting in various aspects (history of science, the cumulative process of science, technology and innovation, electricity teaching, creativity). All in less than 1 hour.
a brilliant scientist, but sadly his theories weren't originally accepted amongst his peers. Faraday, although a great experimental scientist, wasn't a mathematician, so was unable to prove his theories regarding electrical/magnetic fields. fortunately, years later, he met and befriended the equally brilliant, mathematician, James Clerk Maxwell, who was able to formulate all of Faraday's experimental work & prove him right
@@johncarlisle6865 James Clarke Maxwell, I place him next to Sir Isaac Newton. He opened the door of modern science. Genius, no other word for this great mind & personality. We learned Electromagnetic Waves & Radiating System in college. It amazed me.
@@amritpatel3794 he's not known as the Scottish Einstein for nothing, & yet sadly, very few people outside of the science/electrical engineering realm have actually heard of him & that includes Scottish people
@@johncarlisle6865 My best friend, college colleague, started a company in India. And he kept his company's name, Maxwell Automation, in honour of James Clark Maxwell.
I watch a lot of lectures of that kind, as an electronics technician, but I find this one having poorly made experimental devices to prove Faraday's observations and kind of messy presentation of the progression of his thoughts. On the other side I enjoyed the displayed pages of that marvelous historic book. But it's still enjoyable for history of science lovers.
Loved the one-off demo of the motor on the earth's magnetic field! I would love to see the breakdown of a modern electric motor and electricity generator with Faraday's principles. Had a Lego train in early 80s with an engine that used an electric motor, powered off a big old D-cell battery.. The kids' 2000's toys had a few motors, of various torques. I would love to see how potential difference (voltage/Alesandro Volta) and current (amperage/André-Marie Ampère) affect the motion of electric motors... A fly v. an eagle... Thanks! Love RI vids.
You mentioned that he started out in the publishing industry and became one of the greatest scientific minds of his age it sounds an awful lot like another publisher from America who did the same thing Benjamin Franklin!
I completly agree with the fact that he was not only a scientist,I Watched some documentaries about his Life and read one of his books and I immediatly realized the same thing.He was especially a person Who understood and tried to make through physic the Natural world seeable to everyone.
Thankyou for this RI. Magic delivery about magical methods, pure magic...Imagined I was watching Micheal Faraday from within the RI theatre back in the 1820s but really on my TV , truly entertaining and profoundly mysterious
Excellent. I have worked in electronice for several decades, but I learned a lot fron these demonstrations of Faraday's insights and experiments. Thank you.
I enjoyed the process of discovery by recreating experiments with genuine equipment used by Faraday. I only have a problem with the digital and mechanical detectors. In fact, this is (after viewing many other videos all using modern day detection equipment) what aroused my interest at the start- only to be disappointed at the end. But definitely a very interesting lecture!
It seems to me that in the last experiment the rotation should have been clockwise (CW) when viewed from above. Every time it was pushed in the CCW direction, it slowed down and wanted to reverse to CW, but each time it was nudged again in the wrong direction. I'm assuming that the black wire is negative, and the red wire is positive, and the Earth's flux is pointing somewhat downward, and the current flows inward on the spokes (conventional flow is positive to negative,) or the electron flow is outward on the spokes (electron flow is negative to positive.)
Well, it certainly didn't work, though Ricketts acted as if (pretended?) it did. (ca. 53:00 to 55:00) and it DOES *seem* to work when the assistant pushes it clockwise ca. 54:00, it's uncertain, but it is clear it stops at 55:25 after Ricketts pushes it (after apparently coasting).
Fleming's left-hand rule for motors says it should have turned clockwise when viewed from above. The index finger is pointed downward in the direction of the Earth's magnetic flux. The middle finger is pointed towards the center pivot point in the direction of the "conventional" current flow which is positive to negative. The thumb points in the direction of motion which in this case is clockwise. I performed the experiment myself to verify this, and it worked. The torque is extremely weak.
It's an amazing lecture. But what I don't understand: when he demonstrates how the bent wire is supposed to go around, @32:30 doesn't that also happen with a simple "repel" action since there's a fixed axis?
I have always imagined what it would have been like if Faraday and Tesla were best friends or Brothers. We would all be flying around in our own space ships by now.
he was fortunate to meet another genius in James Clerk Maxwell, but I agree with you & wish all 3 of them could have met & put their Mega brains together
Had no clue he built a motor which worked with the earths magnetic lines of force field. Didn't even have a clue it was possible. I keep learning thankyou RI!
Most people don't realize that eletricity was one of the greatedt achivement of mankind, we used something invisible and yet were able to tame this "thing". Only years later, the electron was discovered. Then we discover the electric waves, semiconductors, the transistors... And now we can watch a video with a device on our hands!!!
It is always amazing to hear about the leaps of intuition or knowledge that lead to great (or even small) things. To me the take home message here should come at about 55:30... "he was not educated in the traditional means". This is still happening of course and it is pretty well understood even now that most kids have their creativity squashed by the present school system by the time they are about 12. Too bad the education systems of the european tradition (the only one I have any knowledge about) has not endeavoured to earn that lesson over the past 200 years. Just think where we could be by now (if Faraday's example is anything to go by) if there were more 'less educated' people that were free to pursue their creative genius...free from an education system that focuses on educating to get a job. Tesla was another genius but he was crushed by the capitalistic greed of how the system worked. Will we ever 'learn'?
Interesting Michael Faraday's process. As an inventor myself, I'm particularly weak in observational skills. Not so, for Michael. However research is important and I agree that an independent approach can yield good results. I've invented pumps, engines, direct upwind prop/windmill yachts, XRAY hologram to visible light process, heat to electricity surface and written my own software, designed circuit boards, PCBs and 3D objects. The tools we have today are fantastic as are our research resources. There are people who can achieve well beyond me academically but at the age of 11 I decided to be an inventor and I expanded my mind and skills in that direction. As with Michael Faraday looking at the interaction between electricity and magnetism, food for an inventor consists of mental challenges and appropriate building blocks to achieve solutions for those challenges. Understanding practical physics and bringing it into every day life is important. Learning about other forces, prior art, other technologies. For example you've glossed over electrostatic repulsion of light charges, there's been no scope for photon powered motors, piezoelectricity or a myriad of other effects but they all are inventor food. Another of my inventions, reinvented by a guy who uses an effect i thought up in my early 20's, piezoelectric motors. Using waves of electrically generated deformation to slowly rotate a shaft or move a linear actuator. Some of us are brilliant at those initial sparks of an idea but lack the narrow minded focus to refine only one invention when others are also tantalizingly distracting. A part of our future forays into inventing relies on extending our physics perceptions beyond our human constraints. Above and beyond the visible rainbow frequencies, sound above and beyond our own hearing, forces our bodies have poor sensitivity to. Expanding our understanding of Scent- Luca Turin's genius exposed in his TED talk on scent is a fantastic start. Understanding not only inter-mitochondrial communications, but also how those communications impact our own nervous system. As fungi have been observed to solve mazes, it is naïve to think that our DNA and our mitochondria are not intertwined through the evolution over the millennia in ways exceeding the Krebs cycle alone. My intuition tells me that instincts are passed through the mitochondria rather than our human DNA. The potential for cellular memory storage escalates the possibilities for recall-Contemplate the book "The holographic paradigm" with this in mind. We are walking, talking biological bipedal symbiotic communities with all the arrogance of humans thinking we are something special in the same way as we rejoice in a national sports win, taking vicarious pleasure in other's successes, when it is only as a world community that we achieve those human things that we rejoice in. Animals, mushrooms. Symbiotic protein. We are no different.
For more history on Faraday's experiments and how James Maxwell mathematized them, I highly recommend the book _Faraday, Maxwell, and the Electromagnetic Field_ , by Nancy Forbes and Basil Mahon. One of the best non-technical science books I've ever read.
interesting fact that Benjamin Franklin who laid the very foundations of understanding electricity (charge, +/-, lightning) also started out as apprentice in book printing. Also using it as source for books he would not otherwise have had. He was also probably the first american who was made a fellow of the royal society. He also, just on the side first used the terms positive, negative and battery for electricity. Sadly mostly reduced to the kite thing today. Which he did but not as suicidal as ususally portraied. And another parallel: despite being a very capable businessman, never patented any invention. The lightning rod for example would have made him fantastically rich but he gave it away for free. As he did his scientific ideas and theories, so some were proven by others before himself. Like the lightning=electricity thing.
Great comment! It made me think about the headlong rush there exists today for eminence and the Nobel Prize. Giving away a prototype is the move of a REAL scientist, in the broadest and best sense. Maybe there should be a prize for advancing humanity through scientific work, not just for innovation?

e. Basically a 'battery' has been created inside the electrical wire itself, different areas of electrical potential. Basically a 'wire battery' or a 'batteryless battery', however one wanted to call it.
f. Numerous cones placed end to end increases the number of 'batteries' in the wire.
(In series to increase voltage, in parallel to increase amperage).
* Via QED (Quantum Electro Dynamics) whereby electromagnetism interacts with electrons in atoms and molecules, one would have to find the correct 'em' frequency for the correct material being utilized for the cones. The shape of the cones could also come into play. The type and size of the wire as well as the type and thickness of the insulation between the cones and the wire would also be factors.
* Of course also, possibly 2D triangles made up of certain materials with a conductor going down through the center of the triangle could possible achieve the same 'batteryless' battery system.
* Plus possibly with the 2D concept, layered 2D's that absorb different energy frequencies, thereby increasing the net output.
To help protect against at least some harmful cosmic radiation:
(copy and paste from my files):
MODIFIED MOLECULES:
More dense molecules with potentially new characteristics created primarily for potentially better protections from harmful cosmic radiation in outer space as well as different applications on planets and moons.
Setup:
a. A more complex molecule.
b. It exists under:
1. A certain gravitational energy field.
2. Under certain electrical interactions.
3. Under certain magnetic interactions.
4. In a certain temperature.
5. In a certain pressure.
Modification:
a. Change 1 or more of the above items to change the shape of the molecule.
Effects:
(When modification item[s] removed):
a. Molecule returns to it's original shape.
b. Molecule returns to a shape larger than it's original shape.
c. Molecule returns to a shape smaller than it's original shape.
d. If larger than or smaller than it's original shape, then possibly the same molecule with different interacting characteristics, and if smaller than it's original shape, then a more dense molecule.
e. Other atoms and/or molecules might be able to be attached to this 'new' material, and the 'new' larger molecule could possibly be modified as above yet again and on and on. The possibilities are virtually endless.
f. New 'space age' material being formed for various uses.
@@charlesbrightman4237 Both of your proposed applications will require some imaginative and rigorous experimentation. Have you taken Faraday’s example and begun working on those experiments? Wouldn’t it be fun, and valuable, even if they didn’t quite do what you wanted?“Prototype” the results, contribute to future missions! Faraday would have!
It's beautiful to see those young men (probably, 8, 9 or 10 years) be introduced to electromagnetic induction at such a young age, more so the thought process and practical aspect that led to the motor we have today. Where I'm from, engineering students have to memorize Abomasum, and head, thorax and abdomen of a grasshopper.
Always love watching the lectures. Thank you.
The great INVENTOR, MICHAEL FARADAY !
Excellent presentation by Dr. Ricketts to demonstrate Faraday's insights or genius 200 yrs ago. I enjoyed it.
"The Structure of Scientific Revolution" by T.S. Kuhns beautifully describes the paradigm shift. You see the world one way yet anomalies appear. To answer the reason for them you need to see it a different way and when you do; the world changes.
So very interested and entertaining. I spent 50 years in the electrical field and familiar with Faraday. I didn't know much about his early work. Thank you very much.
Visualizing magnetic fields was always confusing to me because of all the little windings in the DC motors I would play around with as a child. There's so much happening inside of the 'modern' motors.
Great presentation!
Peace
Think circuit as flow.
this was a nice discussion and demonstration. i worked with electricity my whole life, in my early days as a radio transmitter repairman in the u.s. air force and then as a lineman for a local municipal power company for 40+ years. i knew of faraday but mostly as a value of capacitance. it was a bit of a refresher on the early rudimentary basics of electricity. sometimes one forgets and then remembers about how much one has learned, known and experienced in life. thnx.
I was on the edge of my seat.
This is crazy good storytelling.
Truly incredible and educational. The voice demo was eye-opening. Faraday was really something.
I became a fan of Michael Faraday when I was grade 8 (14 yrs old) I still like his physics.
Great demonstration and lecture about Michael Faraday and the process of innovation. Thank you so much for this and have a phenomenal day.
If everyone in the factories took as many safety precautions as you did for every slightly hazardous job.. nothing would ever get done. We are all fortunate that skilled labor takes the chances that they do.
And indeed -there was NO need for it!! - He isnt inviting members of the audience up to do anything contentious. As fa as I could see there was nothing more "dangerous" than a 9V pp3 battery !!
It almost sounds as though you are on the Board of such a company and thinking about cutting expenses at the risk of your employees? But if so, reconsider. Today’s skilled laborers have unprecedented access to legal recourse. And don’t put your comment in company correspondence - it will end up in some clever attorney’s brief and triple the punitive damages. lol. Of course, you may have a different reason for posting this. If you don’t mind, what is that reason? Respect, Jeff🙂
This is beautiful! This is a fine example of how great the internet can be! Amazing thinking, great works of art, and new ideas exchanged! ❤️
Good lecture hindered by poorly produced experiments.
The techies also really should have adjusted his mic to stop us hearing his nasal breathing. Really distracting. And he skipped so much interesting detail - like he couldn’t wait to finish and go home; seemed impatient with his volunteers too.
Poorly produced lecture too. He took "next slide please" to a new exasperating extreme.
Yes -such a shame. It isnt that difficult to produce decent demo equipment that gives predictable results. Especially when doing it for the RI !!
Really was embarrassing to see him trying to get poorly produced demos to work - then giving half hearted apologies to his audience when they didn't work
I think it was poorly planned, poorly rehearsed -and when it went wrong - he had nowhere to turn. ( apart from "turning the next slide2)
And as for the disguised recording of "celebrating 200 years of the electric motor etc" - who the heck thought that was a good idea ??.
A good lecture but I doubt if it did true justice to MF.
Thanks by the way for a great presentation!
Love this seminar. very well explained. thanks for posting.
Enjoyed your presentation. What a honor for you to be at RI. S/V North Star is in Ensenada, MX after 5yrs Sea of Cortez we are done.
Great lecture and very interesting in various aspects (history of science, the cumulative process of science, technology and innovation, electricity teaching, creativity). All in less than 1 hour.
Thank you for a wonderful presentation.
Instead of Mercury, non-toxic Gallium metal heated to above its melting point of 29C may be used.
Superb lecture. Thank you
Just love the insights RI lectures give. As Faraday said "beautiful" Thanks!
What a great clip with a lot effort in
I bet Faraday and all the other scientists interested in electricity would've loved to have the magnets that we have available today
FANTASTIC RECREATION WHAT MICHAEL FARADAY DID IN 19TH CENTURY ! I APPRECIATE IT BY HEART AND SOUL . THANKS !
Magnificent! Many thanks for this lesson!!!
Mike, I absolutely love that you include the extended model precip totals. Of course it's fantasy land but it's still fascinating to us weather nerds
Excellent video, really enjoyed it.
These talks are super interesting. I've seen a couple and they are good.
Michael Faraday was just Genius. And I am an electrical Engineer. I can appreciate his brilliant mind.
a brilliant scientist, but sadly his theories weren't originally accepted amongst his peers. Faraday, although a great experimental scientist, wasn't a mathematician, so was unable to prove his theories regarding electrical/magnetic fields. fortunately, years later, he met and befriended the equally brilliant, mathematician, James Clerk Maxwell, who was able to formulate all of Faraday's experimental work & prove him right
@@johncarlisle6865
James Clarke Maxwell, I place him next to Sir Isaac Newton. He opened the door of modern science.
Genius, no other word for this great mind & personality. We learned Electromagnetic Waves & Radiating System in college. It amazed me.
@@amritpatel3794 he's not known as the Scottish Einstein for nothing, & yet sadly, very few people outside of the science/electrical engineering realm have actually heard of him & that includes Scottish people
@@johncarlisle6865
I saw the video on TH-cam. Even common Scotish can not recognized his statue in a middle of the town. So sad.
He died too early.
@@johncarlisle6865
My best friend, college colleague, started a company in India. And he kept his company's name, Maxwell Automation, in honour of James Clark Maxwell.
spectacular presentation!
Thank you for this lecture, owesome genius man in history
That was brilliant. Thanks for sharing.
Thank you for the video.
Wonderfull presentation ,one of the most important step into human history ...
Wonderful history lesson.
Beautiful. First principles and an open mind.
excellent lecture and demos
Superb lecture
Nice show for those present - shame some of the demos were over before the cameras could catch up!
I watch a lot of lectures of that kind, as an electronics technician, but I find this one having poorly made experimental
devices to prove Faraday's observations and kind of messy presentation of the progression of his thoughts.
On the other side I enjoyed the displayed pages of that marvelous historic book. But it's still enjoyable for history
of science lovers.
Immersed in a fluid, thank you Royal Institution. Thank you, David Ricketts.
Loved the one-off demo of the motor on the earth's magnetic field!
I would love to see the breakdown of a modern electric motor and electricity generator with Faraday's principles.
Had a Lego train in early 80s with an engine that used an electric motor, powered off a big old D-cell battery.. The kids' 2000's toys had a few motors, of various torques. I would love to see how potential difference (voltage/Alesandro Volta) and current (amperage/André-Marie Ampère) affect the motion of electric motors... A fly v. an eagle...
Thanks! Love RI vids.
Wonderful told story.
insights change everything.
You mentioned that he started out in the publishing industry and became one of the greatest scientific minds of his age it sounds an awful lot like another publisher from America who did the same thing Benjamin Franklin!
That was fantastic thank you
best demo I have seen of Faradays work, thanks
You must have been watching something else ?
I completly agree with the fact that he was not only a scientist,I Watched some documentaries about his Life and read one of his books and I immediatly realized the same thing.He was especially a person Who understood and tried to make through physic the Natural world seeable to everyone.
Excellent presentation..
Thankyou for this RI. Magic delivery about magical methods, pure magic...Imagined I was watching Micheal Faraday from within the RI theatre back in the 1820s but really on my TV , truly entertaining and profoundly mysterious
excellent. thank you
Excellent. I have worked in electronice for several decades, but I learned a lot fron these demonstrations of Faraday's insights and experiments. Thank you.
brilliant man
beautiful!
Awesome experiments.
Nice job!
I enjoyed the process of discovery by recreating experiments with genuine equipment used by Faraday. I only have a problem with the digital and mechanical detectors. In fact, this is (after viewing many other videos all using modern day detection equipment) what aroused my interest at the start- only to be disappointed at the end. But definitely a very interesting lecture!
It seems to me that in the last experiment the rotation should have been clockwise (CW) when viewed from above. Every time it was pushed in the CCW direction, it slowed down and wanted to reverse to CW, but each time it was nudged again in the wrong direction. I'm assuming that the black wire is negative, and the red wire is positive, and the Earth's flux is pointing somewhat downward, and the current flows inward on the spokes (conventional flow is positive to negative,) or the electron flow is outward on the spokes (electron flow is negative to positive.)
Well, it certainly didn't work, though Ricketts acted as if (pretended?) it did. (ca. 53:00 to 55:00) and it DOES *seem* to work when the assistant pushes it clockwise ca. 54:00, it's uncertain, but it is clear it stops at 55:25 after Ricketts pushes it (after apparently coasting).
Might be right there, as it didn't spin very well when he did it
The weight of the solder connection on the loop may have contributed to the situation. Would have to play with it for a while.
Fleming's left-hand rule for motors says it should have turned clockwise when viewed from above. The index finger is pointed downward in the direction of the Earth's magnetic flux. The middle finger is pointed towards the center pivot point in the direction of the "conventional" current flow which is positive to negative. The thumb points in the direction of motion which in this case is clockwise. I performed the experiment myself to verify this, and it worked. The torque is extremely weak.
@@solarfluxman8810 Cool. What current and voltage did you use? (and how many turns?)
It's an amazing lecture. But what I don't understand: when he demonstrates how the bent wire is supposed to go around, @32:30 doesn't that also happen with a simple "repel" action since there's a fixed axis?
Fn great!! thank you!
great stuff
I have always imagined what it would have been like if Faraday and Tesla were best friends or Brothers. We would all be flying around in our own space ships by now.
he was fortunate to meet another genius in James Clerk Maxwell, but I agree with you & wish all 3 of them could have met & put their Mega brains together
Had no clue he built a motor which worked with the earths magnetic lines of force field. Didn't even have a clue it was possible. I keep learning thankyou RI!
Most people don't realize that eletricity was one of the greatedt achivement of mankind, we used something invisible and yet were able to tame this "thing". Only years later, the electron was discovered. Then we discover the electric waves, semiconductors, the transistors... And now we can watch a video with a device on our hands!!!
It is always amazing to hear about the leaps of intuition or knowledge that lead to great (or even small) things. To me the take home message here should come at about 55:30... "he was not educated in the traditional means". This is still happening of course and it is pretty well understood even now that most kids have their creativity squashed by the present school system by the time they are about 12. Too bad the education systems of the european tradition (the only one I have any knowledge about) has not endeavoured to earn that lesson over the past 200 years. Just think where we could be by now (if Faraday's example is anything to go by) if there were more 'less educated' people that were free to pursue their creative genius...free from an education system that focuses on educating to get a job. Tesla was another genius but he was crushed by the capitalistic greed of how the system worked. Will we ever 'learn'?
Interesting Michael Faraday's process. As an inventor myself, I'm particularly weak in observational skills. Not so, for Michael. However research is important and I agree that an independent approach can yield good results. I've invented pumps, engines, direct upwind prop/windmill yachts, XRAY hologram to visible light process, heat to electricity surface and written my own software, designed circuit boards, PCBs and 3D objects. The tools we have today are fantastic as are our research resources. There are people who can achieve well beyond me academically but at the age of 11 I decided to be an inventor and I expanded my mind and skills in that direction. As with Michael Faraday looking at the interaction between electricity and magnetism, food for an inventor consists of mental challenges and appropriate building blocks to achieve solutions for those challenges. Understanding practical physics and bringing it into every day life is important. Learning about other forces, prior art, other technologies. For example you've glossed over electrostatic repulsion of light charges, there's been no scope for photon powered motors, piezoelectricity or a myriad of other effects but they all are inventor food. Another of my inventions, reinvented by a guy who uses an effect i thought up in my early 20's, piezoelectric motors. Using waves of electrically generated deformation to slowly rotate a shaft or move a linear actuator. Some of us are brilliant at those initial sparks of an idea but lack the narrow minded focus to refine only one invention when others are also tantalizingly distracting.
A part of our future forays into inventing relies on extending our physics perceptions beyond our human constraints. Above and beyond the visible rainbow frequencies, sound above and beyond our own hearing, forces our bodies have poor sensitivity to. Expanding our understanding of Scent- Luca Turin's genius exposed in his TED talk on scent is a fantastic start. Understanding not only inter-mitochondrial communications, but also how those communications impact our own nervous system. As fungi have been observed to solve mazes, it is naïve to think that our DNA and our mitochondria are not intertwined through the evolution over the millennia in ways exceeding the Krebs cycle alone. My intuition tells me that instincts are passed through the mitochondria rather than our human DNA. The potential for cellular memory storage escalates the possibilities for recall-Contemplate the book "The holographic paradigm" with this in mind. We are walking, talking biological bipedal symbiotic communities with all the arrogance of humans thinking we are something special in the same way as we rejoice in a national sports win, taking vicarious pleasure in other's successes, when it is only as a world community that we achieve those human things that we rejoice in. Animals, mushrooms. Symbiotic protein. We are no different.
For more history on Faraday's experiments and how James Maxwell mathematized them, I highly recommend the book _Faraday, Maxwell, and the Electromagnetic Field_ , by Nancy Forbes and Basil Mahon. One of the best non-technical science books I've ever read.
It would be great to do an animation of Faradays actual use of mercury to develop his ideas.
Mercury was used just to negate the friction. That's all.
@@twt000 and power delivery, closing the circuit.
@@jyvben1520 There was a crude mercury switch?
interesting fact that Benjamin Franklin who laid the very foundations of understanding electricity (charge, +/-, lightning) also started out as apprentice in book printing. Also using it as source for books he would not otherwise have had. He was also probably the first american who was made a fellow of the royal society.
He also, just on the side first used the terms positive, negative and battery for electricity. Sadly mostly reduced to the kite thing today. Which he did but not as suicidal as ususally portraied.
And another parallel: despite being a very capable businessman, never patented any invention. The lightning rod for example would have made him fantastically rich but he gave it away for free. As he did his scientific ideas and theories, so some were proven by others before himself. Like the lightning=electricity thing.
Great comment! It made me think about the headlong rush there exists today for eminence and the Nobel Prize. Giving away a prototype is the move of a REAL scientist, in the broadest and best sense. Maybe there should be a prize for advancing humanity through scientific work, not just for innovation?
Thank you from the bottom of my heart RI, and David Ricketts.
Hola Sr. DAVID, estoy interesado en el motor que gira oponiéndose al campo terrestre, por favor me podría explicar cuales son todos los elementos imvolucrados? Dónde puedo obtener el circuito eléctrico del esperimento ? Desde ya, muchas gracias.
This is the Royal Inst back to its best,
Very nice presentation! Like a lot to understand Faraday's history and how the world he was living in.
