Fucking magnets, how do they work?

[–] thebestaquaman@lemmy.world 28 points 3 days ago (18 children)

Unironically, magnetism is similar to charge, which is similar to mass.

You (probably) wouldn't ask "But why does an atom weigh anything?" or "why do opposite charges attract?" All these things are just intrinsic properties of matter: they just have them.

So the answer to questions regarding why anything has mass/charge/magnetic moment really come down to "they just do."

Now, if you want to talk about how and why magnets work at a macroscopic scale, we can have a long and interesting chat about long range ordering and phase transitions, but I'll leave that for now :)

This reminded me of Richard Feynman talking about this very topic. Always enjoy rewatching it.

I love watching Feynman prove icp right.
