But that’s true of gravitational forces too, otherwise satellites wouldn’t have constant speed. It’s silly and misleading to say that magnetic forces do no work. If I turn an electromagnet on next to a spoon, the spoon will move and the magnetic force did some work.
It’s the magnets, doing work!
I suspect I’m using a naive macro model and inaccurate terminology whereas you’re using a micro model and accurate terminology.
Is there even such a thing as magnetic force? Reading up a bit, it only talks about magnetic fields.
