Dude this made me feel like a kid in all the right ways.
😏
In grand ironic fashion, I still don't fully get this stuff but I am walking away smarter today. It truly does feel like youthful curiosity. Thank you Mr. Fielding. 😊
Smarter ever time
It was demonstrations like this that sold me on science as a kid. Magnets, wire, and batteries are the most accessible forms of magic a kid can get a hold of. And that feeling of magic never goes away.
@SmarterEveryDay , try to feel like a kid for a little bit every day. See the world with wonderous eyes. e.g. A plant is growing. Why does a part of the stem suddenly decide to become a leaf stem?
I was a Physics Laboratory Technician in local schools for decades. This is hands down the best demonstration of electromagnetism I've seen taught.
I think so too. Good pace; not excessively dumbed down; no dramatics. I know I learned more. It took me ages as a kid with building my own slot cars from parts to understand that kind of DC motor with brushes.
What
This guy has a gift thats for sure

We need an army of guys like this. The thing that often gets overlooked in education is the role of the teacher as inspiration. He knows things, and this is good, but he also conveys the enthusiasm and joy that comes with play and experimentation. For me, fifty nine some years ago, it was a Bell Telephone lineman feeding me old telephone parts and encouraging me to build my first working telephone. I will always remember him.
you nailed it. I feel exactly the same about Jeremy. He was born to do this
It is my understanding he is self taught which makes him a more phenomenal teacher
You know the saddest part of this all? Tesla died alone and poor. He made his design free for everyone to use for the betterment of humanity and got literally nothing in return.
Sadder is that people believe that story. He didn't die poor. People like him don't care about the perception of wealth, he ghost wrote many army patents. Worked for the govt through the 30's. He knew that people who run America are about money and the external perception power, so why fight that after a certain point. Just yolo'd and did whatever he wanted till he passed because he could build amazing inventions easily.
That was the whole point. And to be frank I wouldn’t say he was alone we still know him today and he is widely respected that’s the farthest thing from being alone
Got "inducted" into the hall of fame.
Wow, that's some poetry.
I was wondering if I was the only one noticing this.
lol
Lol and "hall".
@@DavidCardone OMG didn't even think of that one. Great!!
@@game-f-un-limitedgamer8958 yeah i dont get it.
Great series. I'm almost 75, and still learning as much as I can. Thank you Jeremy. When people stop wondering and learning...SEND FLOWERS.
Age isn't anything but a number, my friend! Einstein said "“once you stop learning, you start dying.' I like the way you put it better. :D
I'm 70 and coming right up behind you Bob.
You have a few years on me and l thought Tesla was a head of his time till l watched. The lost History of Earth. 5 hours long. And it's wild
The most impressive thing about the shorted core ac induction motor is that when he invented it; he drew it in the dirt with a stick - true story
Now ……..
back in West Europe he was literally dirt poor - just me being punny 🤣
Took my major BSC Hons at the age of 55- it's never too a bad thing to push your knowledge further
I'm an electronic engineer working in the field and I still feel like a kid when I see videos like this! Great job!
If it were ACTUALLY so great, it would self power. Why not, it's sitting on top of the largest induction motor in our local space. Guess he wasn't THAT smart. Now go improve them!
There is no BS degree in electronic engineering. None that I know of. Electrical engineering covers electronics engineering.
Related but kind of unrelated. I'm trying to convert a motor from caterpillar fan into a motor that would work with an electric bike. Would you know where I could find resources that would help me do so?
I agree. I'm an Electronics Technician for Machines and Drive Technology so induction engines are nothing new for me. I wish they would teach this technology as shown in the video in school.
@@melaniecotterell8263 always gotta be that ONE person that has to feel smarter or correct something to make themselves feel better! Hope you got what you wanted!
I'm a retired power engineering and have commissioned countless induction motors and generators of all sizes up to many megawatts and still find this video about the induction motor interesting and entertaining. I have also watched part of the series on the history channel and found that very good viewing. Jeremy - you are a great presenter.
As an engineer i have to tell people im an engineer.
its so odd, he speaks so calmly and clearly but his excitement is so real and genuine its infectious
and he's not wite. Your shocked, so am I.
yes.not only the material, he also the model of engineering teaching that makes engineering is attractive
I'm an electronic engineer, and already knew *everything* that you went over in this video, yet I still watched it to the end, and totally enjoyed it.
*VERY* well done!
Super Geek … Same here. Perhaps we’re also slightly intrigued just to see how someone else is going to present the information so others will comprehend.
@@arthurleslie9669 It's not that hard to comprehend.
@@arthurleslie9669 And entertain... I grew up watching fun, informative and entertaining Royal Institution Christmas lectures televised in the same place Faraday lectured, only to go to university and be bored rigid with my EE degree!
@@A.C.71 ... You should try to teach some of the people I have. Not everyone can process information on the same level.
@@arthurleslie9669 Yes, I admit that is true. We are all on a different level. Some things I will never understand...take women for example lol
I've been an engineer for 30+ years and this is by far the best explanation of induction motors that I've ever seen. Thank You Jeremy for your watchable and informative videos. I hope these motivate new generations to understand the physical world and how it works!
8:00 The old analog car speedometers worked similar to your model. A circular magnet was spun by a flexible cable driven by the output shaft of transmission. This magnet was surrounded by an aluminum housing that was constrained to rotate only 1/3 of a turn by a torsional spring. The faster the magnet was spun, the stronger the FORCE imparted on the aluminum housing, thus the farther the spring was stretched, and the farther the housing rotated. The speedometer needle was glued to the housing, and served as the speed indicator.
The torque on the indicator needle shaft increased in proportion to the magnet/cable rpms.
It's called a hysteresis disk.
Your excitement is infections. Now I understand why induction motors last so long.
Essentially the bearings are all that go bad on them... Replace the bearings and get another 30 years out of them.
@@calholli never thought about that.... Hmmm
@@iwinrar5207 Well.. that's granted that the wire coils are robust enough. they can be made with the wire being too small and the insulation too thin and they overheat and burn up... but with a well made, overbuilt motor-- they should last and last.
Absolutely. I need to go invent something, stat!
@@calholli I had a Dremel that had sheared its coil wiring, it's pretty stupid how flimsy the connection is. I fixed it but then almost immediately another part blew and it would only run at full speed.
Best explanation of electric motors I have ever watched.
My first degree was a professional diploma in Electrical Engineering (from the National Technical University of Athens), and then got to study Computer Science where I am still active today (as researcher/instructor/consultant and developer). Of course, because of my training, I am very well aware of all the principles and applications of electro-magnetism. Even though I didn't like the electrical machines courses that we were taught as undergrads, I really loved your presentation! Congratulations for this beautifully made video that has "soul".
Your video quality and movement from one principle to another has gotten so good over these years I've been following you. Thank you for all your efforts.
I hated EVERYTHING about school, but I could watch Jeremy's videos all day and actually learn.
Thanks Jeremy!

@@dwj77 Are you not glad we are no longer under the law and curses? Again this is not the best place to post your comment as it has nothing to do with the subject at hand.
I would have loved to have a teacher like him on my high school times. Not only teaching fundamentals in a super magnetic way, but providing excitement for knowledge.
I had a stat teacher in uni like this too. In a class with average failure rate of 85%, only 2 out of 30 failed and I was one mark away from HD. In high school my highest maths grade was a c. Thanks Mr Ngigi.
Nobody is giving you credit for the double pun 😂
The way you talk about engineering makes me co-feel the excitement you have to the subject. I enjoyed your video, please keep making more.
Why is this SO wonderfully interesting?! Thanks for posting.
Clarification: The history channel asked me if I would make a TH-cam video about revolutionary engineering, related to their series on engineering coming out this month. I think their show is awesome, but I am not "in" the show. 😀 Sorry about the confusion if that wasn't clear. You should definitely watch the show if you can!
What's the difference between induction and brushless. From what I found it's only the AC/DC current. Is there more to it ?
Induction motors are also brushless
@@JeremyFieldingSr ok, then my PC alone has 12 induction motors. Even the water pump for the CPU cooler uses one. Thanks for the reply. 🙂
@@DuperMate what people call "brushless" motors usually use permanent magnet rotors instead of inductive ones. The motor itself is powered with (usually) 3 phase AC, same as induction motors, but there's a motor controller that takes DC power and emits the AC instead of just wall AC like induction motors (as opposed to brushed motors which just use DC without any controller). Jeremy is of course entirely correct that induction motors have no brushes but that's not what people usually mean when they use the term.
I see appliances like ceiling fans advertising as more efficient by using a DC motor. Is that true or just marketing hype?
Jeremy Fielding is the kind of "influencer" we all need. What a great teacher you are. I'm glad to see your success. I wish I had you for a neighbor.
I hear that!👍🏼

Well explained, you are a good teacher.
This is the best demonstration and explanation of this phenomenon that I've ever seen. I wish you had been my teacher in school. You've earned another subscriber.
I clicked onto this video not expecting to learn much more than I already knew. Not only was I unquestionably wrong in my judgement, your explanations were impeccable and your enthusiasm is frighteningly infectious. Great stuff Jeremy!
ME 2!
As an electric motor mechanic and winder, I absolutely love seeing videos that celebrate how important electric motors are. If they disappeared overnight, society would crumble lol.
I'm a retired master electrician, troubleshooting polyphase motor controls were one of my specialties.
The old style, mechanical motor starters, cap banks, fun stuff, the kind few people can work on since solid state was introduced.
I’m the same way with machining and metalwork. Metallurgy and techniques from the past. I love the machining and metalwork in vintage sewing machines. You can see all the surface finishes and specialty machines they use
I love how simply you explain all this. Good job man. Just watched your video about free energy devices and that was the best explanation I've seen
I've been into electric motors and magnets since I was in elementary school but I never took the time to learn how an induction motor works. I really appreciate your video for finally teaching me, thanks! Love your passion, too...keep up the great work!
There are two universal truths. Electric motors are important, and a Tesla owner will always tell you they have a Tesla
Also Tesla motors have no connection to Nikola Tesla apart from the name
Weird way to flex considering they have nothing to do with eachother

Aren’t you that 50 cal Gun inventor guy?
Mr. Fielding, you are the professor EVERY aspiring engineer and science nerd should have in school! You make these concepts easy to understand and fun to learn. I recommend your channel to every parent and young child I know who expresses an interest in science, engineering and building stuff. Keep up the great work!! P.S. The History Channel could NOT have picked a better presenter for one of their engineering videos. That is AWESOME!!
I am not "in" the show. I just love their show. Sorry about the confusion there. They asked if I would make a video on my channel about engineering that they could sponsor.
@@JeremyFieldingSr I'm counting upwards of 60 electric motors in my little apt. [This may seem like a lot, and it is: I'm a part-time scrapper who really likes to take things apart - I can see three copper coils from where I'm sitting as I'm typing this. I might have a problem]. Also, Mr. Fielding, in your entire approach to everything engineering, you remind me of a Neil DeGrasse Tyson or a Carl Sagan in relation to astronomy. The joy in their/your eyes when discussing their/your specific fields, or the almost childish exuberance they/you exhibit when explaining even the simplest of concepts. It brings hope back to me for the human race...thank you, and may your days be long upon the Earth.
@@JeremyFieldingSr Are you American?
Tesla was the brains behind Edison who was a thief & a liar.
@@JeremyFieldingSr as a friend would say, 🤙💙
Jeremy, I want to thank you for your videos, they are very well presented in a manner that most everyone understands the concepts and ideas. Good job and keep up the good work!
you just made this topic incredibly understandable like a walk in the park. thank you so much sir!
This is science, engineering, experimentation, teaching, fun and love all bundled together !
Thank you Jeremy. You are a Gem.
To bad he is learning still
How can he not know how to make perpetual motion?
@@JoseHerrera-mk7cv it's not possible to know how to do something that can't be done.
Jeremy I'm so proud of you. I remember when your channel was just getting started. You came from humble beginnings and your passion and energy and work has brought you to an amazing place. I still love your videos. I love your enthusiasm and the way you break things down. Please keep up the good work. You are and will influence a new generation of scientists and curious young minds.

God bless you iam feeling life in your comment obviously your heart is put to light and iam motivated.
So I watched sooo many other videos just trying to understand how these motors work and your video was the light bulb moment for me. Thank you so much for this video because I finally understand it!
Your videos are always good but this is honestly one of the best educational videos I've ever seen. Thanks for making it.
You thanking the History Channel is ironic. They are the ones who should be thanking men like you that take the time to share your knowledge and educate others. Keep up the good work. Your style of teaching is great, after decades with a basic understanding of how things work all come together and I fully grasp the concept when you actually show the visual presentations. Maybe I knew some of these things all along but your models definitely solidify my understanding. A simple thank you is in order. Better than any college degree I could go in debt to obtain.
The History Channel doesn't care about education, they just care about ad revenue from credulous viewers. As the WW2 generation died off, they moved from programming which got them nicknamed The 'Hitlery' Channel into conspiranoid nonsense like 'ancient aliens' and 'ghost hunters'.
Wait... so I won't learn awesome technology stuff from pawn shops, ratrod custom shops, and Offshore fishing shows???
God I hate what History, TLC, and Discovery have become...
And that alone is worth becoming an engineer. "Magic" explained and demonstrated by experiments that you can easily replicate and verify on your own, step by logical step. Wonderful.
I love people like you can adequately explain things that I don't understand. Thank you for the Post!
Great video. Awesome presenter. So engaging, its amazing what just smiling and having a clear curious interest in your subject matter can do for a video. Instant sub 👏
Jeremy "Magnetic" Fielding. What a great guy with a great channel. I will boldly rank this one at the very top of my home made science channels list. Jeremy, you ROCK!
Content so attractive, it's magnetic! :D
I love how this man's enthusiasm and voice draws you in and makes you want to listen to him and learn. This was great and I wanted it to go on longer. Tesla must have been shocked by all of his experiments and discoveries.
If you read into Tesla then you'll know he wouldn't be shocked for his discoveries because he never randomly experimented, he would actually create every single detail in his mind first and then make a machine in no time
This is true, not like other “accidental” discoveries.
I am sure he had a shock or 2! 😂😂✌️✌️
Tesla's story is as much a sad cautionary tale in business, as it is a "great inventor" story-- especially seeing the manner in which he died...
One of the reasons, I believe, Elon Musk chose to name his auto company after Nikolo, other than obviously being inspired by his genius, was to revitalize a name and legacy Elon believed not only got short shrift from his peers and contemporaries during his lifetime- but from posterity as a whole...
The scale of Tesla's societal impact is so immense it can barely be measured, yet, relatively no one knew who this guy was until Elon debuted the name of his car company...
Tbh, Tesla's face should be on the $5 bill...
@@chrisnyasia7 Wait until you learn that Elon Musk didn't name the company because he is not the one who found it lol, he brought it 1 year later and kept the name. Elon Musk is the same guy that said he likes Edison more, even tho we all know that he was a fraud and animal killer, so your whole comment is invalid.
"No one knew who this guys was until Elon debuted the name"
Maybe in America because of a terrible school system, but in most Europe counties he is well known, he is also on a 100 dinar bill in Serbia, but he is definitely not appreciated enough.
Best video and the best teacher I have luckily stumbled upon. Good teachers are hard to find. You have a special gift.
I am really enjoying watching your clips, as they are very easy to understand and you explain complex ideas through simple demonstrations. Lots of love. Thank you.
I’ve been fascinated with magnetism for most of my 75 years. Read most of Tesla’s books and books about him. Pure creative genius. Magnetism is the mystery behind induction. I keep guessing and learning. Thanx for your series.
The sheer joy and excitement in your eyes when you talk about engineering is what made me a subscriber. Gotta watch more of your vids. Great stuff and I never knew this about the history or how electric motors worked. Thank you.
Keep doing what you're doing Jeremy. I look forward to learning more
Very cool. I love your inspiring method of communicating. Will be checking out your videos and will look into viewing the History Channel production soon. Thank you for your time, energy, and care. Stay well.
Jeremy, you make this so interesting. I've instructed electricians for 32 years and really enjoyed your presentation. You are a wonderful teacher and best luck on your history channel work. I am sure it will be a big hit.
How do I get to look at this history channel ?
Yeah what history channel show!?!? Please answer @ Mike Fox
@@Salomessanctuary agreed! Someone help us find this History Channel PLZ!?!?
@@rb88dhb I think he mentioned it when he was doing his presentation. Not sure it has been months since I posted this.
Never thought about being motor rich in my house. Great video. If you were a teacher, you would easily be able to get kids excited about engineering.
I'm going to set my DVR for the series.
He **is** a teacher. ;)
i needed this video to help pass a class so thank you bro......
Bravo Jeremy. I too am an electronics guy, and must say your demonstration and narrative was outstanding!
That's just a fantastic demo of the EM principles behind the most ubiquitous application in induction motors Jeremy. Certainly, this takes me back more than 60 years back when I was in secondary school when I got hold of a toy motor and never have been tired of being fascinated by the latest advancements in replacement of the internal combustion in EVs.
One of the most inspirational presentations I have seen in a long, long time - if not the best! Jeremy, you are so good! It is not the induction motor, it is the infection you are spreading with your enthusiasm based on solid knowledge. I am amazed! Thank you Jeremy.
His joy and wonder about engineering is infectious! Keep doing it!
Excelent explicat. Pe înțelesul tuturor. Bravo,faci o treabă foarte bună . Felicitări!
What a great video! I wish I'd had teachers who were even a fraction as good as Jeremy is at not only explaining how things work, but making the explanation absolutely fascinating! Great attitude and compelling enthusiasm.
Jeremy, I've never heard your background, schooling and employment. I truly hope you are a teacher, as that is one of your gifts. The other gift I see is a great mind. Thank you for your videos!
He's a teacher here. So far, 3/4 of a million people in this classroom.
One of the best videos on TH-cam👌👌👌 tons of life long lessons on this one. Play this in the classrooms.👏
Way back in high school I was looking for a project and came across an old ceiling fan that my dad rescued from an old building. It was built by the Century Fan Company sometime between 1930 to 1935. With some help from my dad who is an Engineer we restored the fan and it now hangs in my shop getting used when I need to move the air around. Dad explained to me how it worked but the way you explain it makes me realize that it's an induction motor. Dad probably told me all that but I was 17 at the time and thought I knew everything like all teen agers. LOL. Great video!
Hi Jeremy. I have watched all of your videos that I can find and want to compliment you on the clarity and simplicity with which you present them. You are an excellent teacher. Thank you for sharing your talents - - - 39 years in education.
Jeremy, you are a brilliant teacher. I am glued to the screen every time you do a presentation. You are the very best in so many ways. Thanks for what you do.
I like the way you go over topics. Amateur radio operators use magnets and transformers in many of the items that we use, including antennas and power supplies.
I love how passionate and the joy this brings you. Awesome video
I've been an electronics tech for years. I never stopped to think about how induction motors actually work. You explained it in terms anybody could understand. Thanks for making this video. Nicola Tesla is my hero. If not for him I would have to have invented a bunch of stuff myself.
Jeremy! Your passion is making the world a better place. Thank you for making these videos.
I love your channel, Man!!! This is one of the best channels out there. Keep up the good work!!! All the best!!!
You were born to teach. I thoroughly enjoy your enthusiasm; your smile and the pace of your talking. You also use good camera angles. All around, great videos and I can't wait to watch more
Hi Jeremy, I really loved this presentation. As a retired Industrial Electrician (Mining) having worked in the UK and Canada, I've had experience with many types of motors and still find them fascinating. The Linear Motor and Mag-Lev mass transportation systems will revolutionize travel in the near future making short Airplane flights obsolete.
I've got to say, you're a very good explainer and your enthusiasm contagious in the best way possible.
Thank you!
Jeremy, i love a shop like yours.
Thanks for your info.
Great job. I’ve been in electrical maintenance for 32 years and still working part time at a motor rewind shop that repairs the big 3 phase induction motors, i sent this video to my boss cheers
I love engineering. I love learning anything, however, thought by someone with this much sincere excitement and passion for the topic!
This guy is a great teacher because he loves what he does.
It looks like most of the people commenting are adults. I encourage each and every one of the people commenting, to grab a kid and let them watch this with you.
I greatly appreciate the simplicity and completeness of your presentation.
Love these demonstrations! You explain it so well, Jeremy!
I am not a good teacher by any means, yet I have held quite a few 'classes' on theory of physics, it is not easy! Hats off to you because you teach me quite a bit, you are in "layman's terms" a Gr8 teacher by nature. A real gift.
Thanks much Jeremy. "Professor Eric Laithwaite: Magnetic River 1975" is a must watch after this video.
You have a joy for learning and it shows. Thank you for sharing what you have learned
Your videos are awesome and I love your enthusiasm! Nicely done. 👍
My god, you really know how to elicit that child-like fascination; at least from me.
This was so simple, yet totally fascinating. The simple experiments/demonstrations really hammered the points home.
We need sooooo many more Jeremys in the world ... this never gets old watching the child like adventure and excitement he emits
You can count me in... eheheh though just never started yet.
Your elegant, and informative explanation of this wonder of the world got the like a subscription. Aloha Sir, good day!
Loved the video. So clever that someone worked this out
Congrats Jeremy on your collaboration with the History Channel! That’s huge, man! I don’t have cable but I hope to find a way to watch it
Just to be clear, They asked if I would make a video on my channel about engineering that they could sponsor since their show is about engineering. I am not "in" the show coming out on the history channel. I just love their show.
Nice 👍
this is pure genius yet we all take it for granted everyday, I loved learning about this,wish Tesla was still here, imagine the things he would have done.
He didn't invent the induction motor. Or much else that actually worked.
@@vorpalblades No, just AC generation that is used all over the world!!
Very cool! Your delivery is top-notch and interesting to boot! Thank you.
Great video! I’m an electrician and love to watch stuff like this to keep learning. The wheel with the magnets reminds me of an ac compressor in a car. Turn on the ac and the electromagnet pulls the plates together at the pulley to engage the condenser. So awesome to understand why things work the way they do haha
Jeremy, c’est incroyable comment tu passes le message harmonieusement. J’ai hâte a tes autres videos et ton enthousiasme est inegalé. 👍
Jeremy, from the first day i saw you stripping down old washers and maKing shop tools from their parts, i was hooked! Some folks have expanding minds, you however, possess an ever blowing mind that is inhaling the universe as you share it in terms though sometimes beyond me, in interesting, elementary and in bites i can actually chew on.
You have one especially valuable item that is not a tool pre se but speaks volumes of how your mind works, and that is your logo. I recall so clearly you philosophy making what you need from what you have like scalable wooden gears,
It has always been a joy to watch you and want to tell you how much I missed you while you were in transition from that incredible garden shed of a shop to what you have come to at this point.
Dude, i am a disabled senior who's mind you spark with your apparent grasp of all thing and ability so share them.
Thank you Jeremy, i look forward to more of your insight, knowledge and experience.
Be well, Ray
I admire your work sir. Thank you for teaching us
My name is Eddie and I've been watching TH-cam for so many years and have never posted a comment in all my years until now... This is the coolest most informative video I've seen... You broke it down so we I totay understood exactly what you were telling me thank you so much... Can't wait to see more of your videos... And I can't wait to make my own motors and inventions with this concept thank you
Excellent lesson. I spent 37 years wiring, unwiring, replacing bearings and sending out for rewinds hundreds of 4160V Three Phase induction motors as big as an automobile. For anyone that has had to clean the carbon dust out of a large DC motor and then had to seat 40 brushes knows, the induction motor is the greatest thing since sliced bread. There is also the added bonus of reversing rotation by simply swapping two motor leads.
I'm trying to guess where you worked with 4160V motors. Got to be major horsepower to require that voltage. Pumping stations? Refrigeration plant? Paper or steel mill? Only place I can recall encountering 4160 was the 750HP motors that drive industrial scale refrigeration compressors. Everything else I worked with was 480V, 100HP or less.
@@sootikins I worked for an electrical utility with around 30 various electrical generators using oil, diesel, natural gas and coal as fuel. The largest was a 365 MW coal fired unit. This one had 1500 HP motors connected to fans. It takes a lot of air to burn coal and then move the flue gas after it is consumed. We had thousands of 480 VAC, 3 phase motors and a few hundred DC motors running all of the auxiliary systems needed for the power plants.
@@sootikins We even have 690V instead of 480 in Europe.Large mines and factories. 500 and 1000V is also used but less common.
@@AbbyNormL Thats cool.Is 4160 the highest voltage stuff you worked with?Very large loads in Europe sometimes use 6 or 6.3 kV.
This was such a wonderful explanation. I feel lucky I found your videos. The step-wise demo of what makes it possible was really a great way to get to the heart of Tesla's brilliance. I never really got how amazing the induction motor is despite owning an electric car. One question further, how is the pole switching across all those coils coordinated? Thanks!
Your explanation and visual experiment is awesome, I work with motors every day as a maintenance electrician, and although I have always understood the theory, your explanation really makes it easy to fully understand. Very impressive. Really enjoy your enthusiasm as well. Thanks for the video...subscribed
Amazingly cool video! Thank you for making and sharing it!
Jeremy, that was an absolutely brilliant presentation and explanation of one of the most earth-changing inventions ever. Tesla was a true genius for the ages and I find it amazing that his invention and induction motor principles have remained virtually unchanged to to this day, ~140 years later!
Bravo!
Actually, the invention of the motor (and dynamo) themselves by Michael Faraday was the two of the earth-changing inventions ever, Tesla was the new kid on the block.
@@Witheredgoogie Faraday's motor was of little practical use, compared to Tesla's invention of the 3 phase AC motor. Even Davenport's DC motor (1934) was problematic, though turned out to be practical. People told Tesla he was crazy and that AC couldn't be used to power a motor, but he and Galileo Ferraris independently came up with the 3 phase AC motor in the late 1880's.
Tesla's patents were the real innovations that brought us into the 20th century. Faraday's was just a way to demonstrate a principle.
Outstanding video, Jeremy. I really like the demonstration with the two wheels. I had some pretty great science teachers in highschool, but none did a demonstration of electricity and magnets the I understood as well as that.
You need your own show.
I love how well you describe everything.
BRO! What a great lesson! I'm 52 and didn't understand this stuff much... THANK YOU! Awesome video brother.
