What many people ignore about magnetism, is that you can use special relativity to transform any situation involving only a magnetic field into a situation involving only an electric field, simply by changing how you look at it.

Feynman:

We have found that we get the same physical result whether we analyze the motion of a particle moving along a wire in a coordinate system at rest with respect to the wire, or in a system at rest with respect to the particle. In the first instance, the force was purely “magnetic,” in the second, it was purely “electric.”

Yeah that's the thing, he's not entirely wrong here. Not nobody, but most people don't know what magnets really are.

I recall some other Feynman interview, where they asked him to give a layman's explanation as to what magnetic fields really are, and the greatest science explainer of the last century basically said like nah, I literally can't, you actually have to know the math to understand it and I can't explain it in any way that would make sense otherwise.

Yes, exactly. Even if Trump being not totally wrong is a weird coincidence.
