Question by somone: How can a magnet make a metal move if it is just massless photons?
Photons are massless, its just light, so how can a magnetic field emitted by a something like a magnet cause a metal e.g. iron to move?
I’m kind of guessing that it is related in some way to solar sails (the hypothesized form of propulsion), if it does could someone please explain how this works too?
Thanks
