Richard Feynman Magnets

Richard Phillips Feynman was an American physicist known for the path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the super fluidity of super cooled liquid helium, as well as work in particle physics (he proposed the Parton model). For his contributions to the development of quantum electrodynamics, Feynman was a joint recipient of the Nobel Prize in Physics in 1965, together with Julian Schwinger and Sin-Itiro Tomonaga. Feynman developed a widely used pictorial representation scheme for the mathematical expressions governing the behavior of subatomic particles, which later became known as Feynman diagrams. During his lifetime and after his death, Feynman became one of the most publicly known scientists in the world.

If you aren't a physics student, as he explained, you won't understand any more detailed explanation than he gave (yes he did give one, you just didn't listen).

[tbayley6]

His main point (3:23) is that explanation has limits and ultimately there is no more satisfactory explanation than 'it is so' (6:00). So there is a point at which you have to be satisfied with what you have - you can hope for better understanding in the future but you can't assume you will get it. This is a massive teaching. It negates 99% of the self-important argumentation on YouTube.

Google "fucking magnets"

[Ethan Silver]

Bloody crude explanation:

There are a stream of tiny particles that are pinging between the magnets, conversation of momentum means the magnets are pushed in opposite directions, thus repulsion

Cheating but imagine two people standing on ice throwing a ball to one another and sliding away from eachother

It turns out electrical current generates magnetic fields. When you put the current into a loop it "focuses" the magnetic field in one direction.

fucking magic!

Anyone else here from the ICP video?

[jonny curtis]

When you make an electromagnet like in school, you always form a coil shape. Is that because that shape means that when a current passes through, the electrons move through it in a similar way to the magnet he described in the video?

[Bloodsaberxy]

I like how you didn't answer his question but only directed him to watch a video where in the end Feynman himself doesn't know how magnets 'work' other than the physical formulations and the standard model
