Honestly I have watched a lot of Top Gear and Jeremy Clarkson says James May is boring? He is certainly wrong, he really isn't I am glad I found this channel. James May really makes this stuff interesting, I gotta say I have never wanted to quit my job and learn science more!
4:16 Don't forget, if you put that solid metal into that coil of magnetic wire, which ever way the electricity flows through the wire (DC Current) will create a type of solenoid, ejecting that solid metal out of the winding of wire one way or the other (depending where your positive and negative are). I learned this in my automotive class. Electricity and magnets are so much fun! I sure love me some headsqueeze, you guys are great!
Although the Northern Magnetic pole currently is a 'south' pole the term 'Northern Magnetic Pole' is geographical and refers solely to the pole in the Northern Hemisphere. N and S in regards to Magnets are arbetrary names chosen to represent opposites, + and - could have been used but someone chose N and S
In machine shops we use permanent magnets, but there is a lever that flips a magnetically shielding metal (such as, again, soft iron) around inside the housing to block the magnets force. Electomagnets can fail, and thats dangerous when you are holding many tons off a crane near workers
Earth's magnetic North Pole is actually a magnetic South Pole since the in a bar magnet the North Pole the magnetic force runs in the opposite direction to the Earth's magnetic direction.
How would one even for sure KNOW the earth is for sure "like" a "bar magnet" what if the core is actually non magnetic and rather a magnetic polarized sphere of some kind encircles it ...or else even multitudes of curved "bar magnets" via fissures or veins of some kind were actually the case? Could THAT be for sure ruled out? I'm just saying imagine and iron bubble that is made magnetic ...it could be filled with something not magnetic and how could someone know without x rays of some such? ....side note vaguely related ...is the moon really hollow?
@@dougiequick1 we don't just guess that it's like that. They had to prove it by rigorous scientific papers knowing the inside of the earth and knowing the earth has a core ball of iron they deduced it.
There is a mistake in the illustration about the place of Magnetic poles. Magnetic North pole is in the South hemisphere, not in the North, as different magnetic poles attract each other, compass needle's North pole is pointing towards the South pole of the Earth's magnetic field.
"North" and "South" are geographic concepts (that existed long before people knew how to use or make compasses). Magnets' poles are labelled according to which pole of the Earth they point to. The end with an "N" points to the north pole, the end with an "S" points to the south pole. Again: "As of 2012, the pole is projected to have moved beyond the Canadian Arctic territorial claim to 85.9°N 147.0°W. Its southern hemisphere counterpart is the South Magnetic Pole."
The electromagnetic force technically has no range. That means that a virtual photon could interact with you from across the universe. i.e you are being attracted/repelled from across the WHOLE universe. Physics is such an awesome subject.
Ah! of course. Virtual Photons are the exchange particle, yes that makes perfect sense now I think about it. They are in themselves electro-magnetic, and so therefore exchange the information. What if we never find the Graviton I wonder? Anyway! Thanks for your reply :)
I'VE GOT A BURNING QUESTION!: How much information/education can the average human brain absorb in 2-10 mins (being the average video length most of the channels hold within) ? I see videos from many sci-channels everyday and I can't remember everything after a while. So how much of all the information given in this video for example are we suppose to consume at once? Thank you! - If you think this is an interesting question please like so Head Squeeze can see it on the top. Thanks!
James you got it wrong...Magnets don't "work". W = F.v, but remember F is always perpendicular to v, thus W = 0. Should have talked a little bit about Curie temperature as well. :p
I have an idea to get the fridge magnet off the scrap car .... in the first place if permanent and the elctromagnet the same polarity it will repel it if not just change the polarity of the electromagnet by changing the direction of the current flowing in it , so the magnets would be repelled :)
You seem to be confusing the names of the poles with the fact that opposites attract (i.e., a compass needle's negative end aligns towards the positive pole, and vice versa). In other words, the compass needle's "N" end has the opposite polarity of the Earth's pole it points towards. But that pole is still called "magnetic north pole" (not south). Also, compasses aren't "north seeking" or "south seeking", they align to the Earth's magnetic field; they seek an orientation, not a point.
lets do the more powerful magnets, the coil that has been coiled. 4:17 imagine that solid metal bar is actualy a long thin coiled metal bar making up this much larger coil. those are the really powerful magnets.
North magnetic pole is not magnetic north pole (and the same for south). On North magnetic pole (place on Earth) there is magnetic south pole (the end of a magnet), that's why compasses turn their north end towards it.
On a weaker magnet yes, if the magnet is as powerful as he is implying there will be shot of as the attractive force will not have time to finish flipping the magnet in time, so that it might pull it back
The north pole of the earth's magnet is referred to as the magnetic south pole; and the south pole of the earth's magnet is known as the magnetic north pole. This is because the north pole on a compass magnet is attracted to the south pole of the earth's magnet.
Loved the video! But speacking of magnet relaitefd stuff, could the lhc or the llc ever create enough mass by smashing atoms as to create a black hole?
There is no such thing as gravity, dielectric acceleration IS (so called) magnetic attraction and IS (so called) gravity. It is one and the same thing, the only difference is coherency. A magnet is a coherent and polarized object, any spatial extrapolation is polarization necessitatively. What drives a magnet is point non-specific and no different from any other holographic fractal in that respect. It is field incommensurability. A magnet does not have poles it has the inverse of counter-space. Space is the absence of inertia, it has no properties. Space acts on nothing, time acts on nothing. A field in and of itself has no quantity, no physicality, it is not phenomena. Space is a posterior attribute of a field, therefore it does nothing and acts on nothing. Space and Time are not autonomous forces, this is absurd. Modern science has never adequately defined polarity, or quantified a field for that matter. "A magnet has 2 poles" is a description not an explanation. The loss of inertia necessitates polarity. The rest point in the centre is a result of pressure meditation. It is concentrated there because it is the inverse of space (force and motion) it is counter-space (inertia and acceleration). What we call a magnetic field is a reciprocating precessional hyperboloid resultant of a coherent dielectric object. Electricity is a byproduct OF Phi (magnetism) and Psi (dielectricity). The 800 pound gorilla that shits on the head of modern physics and QM and that is going to turn the world upside down with countless new inventions MUST be and WILL be in dielectrics, not electricity. Classical magnetism does not account for the difference between centripetal convergence and centrifugal divergence and how they interact to cause dielectric voidance/counter-voidance. Which is often incorrectly labelled as magnetic attraction/repulsion. There is no need for a unified field theory; all fields are already unified. What is not unified is human comprehension of the nature of field modalities in relationship to one another. Mother Nature does not do math and complex calculations with virtual particles. The conjugate forces of reality are simplex and have been understood since ancient times, albeit foolishly dismissed by the arrogance of modern society. Peace.
Again: "north" and "south" are geographic concepts. The terms are used in compasses because compasses are used to navigate on Earth, and (when aligned to the Earth's magnetic field), each end points towards a pole. And no one "made a mistake when naming the end of a compass". We put an N on the end that points north because that's what people using compasses care about. When studying magnetism, simply call the ends "negative" and "positive".
4:20 Picking up fridge magnets: Could you not, pick up the fridge magnets with the Electromagnet OFF, then turn it ON in such a way that the magnetism created would be opposite (or the same "pole") as the fridge magnets, thereby making them "jump" off due to the repulsion of like for like poles?
The earth itself isn't a magnet,it's the poles that are magnetic,that's how compasses work,the needle is magnetized (or something like that) so it points to the north pole/hemisphere.(I think)
Not really. Since both the North and South poles are both touching at the same time any magnetic force applied would not only repel but also attract in equal measure, making it neutral.
Yes, and "that definition" is wrong and misleading (as you can see by reading the first three paragraphs of the same page). The part of the needle that points to the Earth's north pole is (the needle's) "south" pole. Manufacturers put an "N" on it because it points to the Earth's north (which is what they're interested in, since people use compasses to navigate on the Earth, and aren't really interested in navigating inside the compass).
where does our body oil (which makes our face greasy) come from? What are they made of? and if collected in sufficient amounts, is it possible to cook with it?
not at all, electro static force, strong unclear force, weak nuclear force, gravitational force, etc... but gravity is also strangely weak, relative to the other forces of the universe.
Going back to the quantum mechanics thingy-ma-bob (yes a real sciencey term) If scientist think there may be a Graviton (virtual particle that transmits gravity) surely, by that reasoning there must be a "magnetron" a virtual particle that does the same for the magnetic force?
Nope! A magnet's north sticks to another magnet's south. So, a compass needle being a magnet, the needle's north points towards the earth's magnetic _south pole_, which is what we call the north pole. And vice versa, the magnetic north pole of the earth is on Antarctica.
Some how I ended up here to answer my question of how magnets work, beyond domains and that high school dribble, I went to the UCLA channel to find out but nothing just the domains crap again and here in the most un-expected place you gave me the answer I was looking for, good work James.
Following from this, you might explore the actual relationship between electricity and magnetism from the same quantum perspective with regard to the electromagnet. Or perhaps induction forges!
Sterling Archer You run in to problems when you have to find out why your magnet don't work. So you watch the video, lear how magnets work and then fix your magnet.
Why can't we replace the electromagnet (coil) in an electric motor with a permanent magnet. Shouldn't it run for a while if not for ever? Can this be then attached to a load (made to do work)?
Yeah, but...how does the actual magnetic FORCE attract or repel like gravity? What is the motivational force? Is it a fundamental force like gravity? Or is it some strange particle?
Electromagnetism does have exchange particles in the form of virtual photons. And you're right about gravity having the graviton as it's exchange particle, however at the moment the particle is still undetected.
Awesome James ... you are a legend. Thank you for sharing ... its your special gift!

You can turn the current in the opposite direction thus repelling the fridge magnets.

How does one sit down and have a coffee with James?
The north pole of the earth's magnet is referred to as the magnetic south pole; and the south pole of the earth's magnet is known as the magnetic north pole.
This is because the north pole on a compass magnet is attracted to the south pole of the earth's magnet.

James May explaining magnets, my life has been completed.
A hydrocarbon (such as methane and ethane) that's had one of it's hydrogen atoms replaced with an OH molecule.
It's a good thing that James isn't a scientist, or I'd be really cross watching this!

Not really. Since both the North and South poles are both touching at the same time any magnetic force applied would not only repel but also attract in equal measure, making it neutral.
Good job Head squeeze :)
I misread that as morons. Not that it matters of course they are synonyms

where does our body oil (which makes our face greasy) come from? What are they made of? and if collected in sufficient amounts, is it possible to cook with it?
And then the magnet flips around and it's again stuck against your electromagnet. :-)
Because the other two haven't been using the Danger Magnet!
Did anyone catch the "Ring Clarkson" note on the fridge? :P
Omg. So much experiments I need to try at home!!
Ring Clarkson, on the fridge note.
Juggalo approved!
Now go back to racing eccentric and fast cars while making fun of Jeremy, captain slow! Lol
It's one of the four fundamental forces (strong, weak, gravity, electromagnetism). It's basically the result of an exchange of photons.
I like how they said the magnetic north and south poles were on the wrong ends of the earth South is in Canada
freaking magnets this how they work
I wish James was my physics teacher
not at all, electro static force, strong unclear force, weak nuclear force, gravitational force, etc... but gravity is also strangely weak, relative to the other forces of the universe.
what is wind ? and how does it happen?
Reversing the polarity of the electric magnet should repel the stuck fridge magnets, no?
Going back to the quantum mechanics thingy-ma-bob (yes a real sciencey term) If scientist think there may be a Graviton (virtual particle that transmits gravity) surely, by that reasoning there must be a "magnetron" a virtual particle that does the same for the magnetic force?
What kind of magnets are refrigerator magnets? answer at 4:47
Captain slow!!☺️👌👍
on your final point James if you reverse the polarity of the magnet the fridge magnets will be repeld
So does the piece of iron in an electromagnet eventually become permanently magnetized from being subjected to such high levels of magnetism?
Iron dosent stay permanently magetised.
A piece of steel used in the same way would stay magnetised.
I don't know why this is.
Nope! A magnet's north sticks to another magnet's south. So, a compass needle being a magnet, the needle's north points towards the earth's magnetic _south pole_, which is what we call the north pole. And vice versa, the magnetic north pole of the earth is on Antarctica.

Has anyone sent this to the Insane Clown Posse?
...am I being super dated by even making that joke?
Why would the magnetic pole closest to the Earth's north pole be called "magnetic south" (or vice-versa) ?
A Question ...
how is atomic Nuclei even possible , protons should be separated by their repulsion ??
James, Why does Helium make your voice all squeaky when breathed in?
(insert Insane Clown Posse reference here)
How were ions found?
Perhaps, now, Insane Clown Posse will finally be satisfied with this answer.
Saying that the earth IS a magnet is a bit simplified, the earths core is made up of iron, and the churning causes it to become a magnet

Why can't we replace the electromagnet (coil) in an electric motor with a permanent magnet. Shouldn't it run for a while if not for ever? Can this be then attached to a load (made to do work)?
Iron nickel and colbalt, the 3 magnetic elements
Captain Slow FTW
why so? can you give a more detailed explanation, thanks
Correct guys, the magnetic north pole is in the earth's south pole, NOT the north pole, like in the video
You need to turn the magnet on and off to keep the wheels going
The 9 dislikes are ICP and all their fans.
Yeah, but...how does the actual magnetic FORCE attract or repel like gravity? What is the motivational force? Is it a fundamental force like gravity? Or is it some strange particle?
