How DO they work?

A bunch of tiny electric fields spinning in the same direction, essentially.

Why does that attract metal though?

I am pretty sure that there are little bits of gravity stuck inside of them. Either that or witchcraft.

Electric force + Relativity = Magnetism

Because metals (and everything made up of atoms) are also made up of tiny spinning electric fields

why come there is spinning electric fields in a vacuum? whats spinning?

you fucking idiot. permanent magnets, as pictured in OP, work nothing like that.

Vaccum refers to an absence of gases, not solid matter.

Why can't they both spin in place undisturbed? Why the attraction?

this video is beyond wrong and the people who made it should be fucking ashamed.

moving charges generate magnetic forces at speeds FAR FAR FAR less than anything approaching c. There is no effective length contraction at these low speeds. This explanation is patently false and isnt even close to the actual reason.

Stop spreading this bullshit, anon.

>> No.6914213

>>6914203
the video says that the charges are much much much smaller than c

but there's so many electrons and the electric force is so hugely strong that even the minute effects of length contraction at those slow speeds produce a noticeable force

the math backs it up bro

Because it is more efficient for them to be aligned. It costs less energy when they are near each other if they are aligned

An electric field doesn't need space to be gaseous. Not sure what you're referring to.

Magnets are only magnetic when the effects take place ?
how can we tell if something is not magnetic without testing it against a metal or another magnet ?

Probably everything that can be said about it without using math to fake a feeling of understanding.
