if electromagnetism is mediated by photons, what do photons have to do with magnetic fields?
more specifically, what is a magnetic field "made" of? surely there aren't photons released by an ordinary household magnet? i have a vague understanding that magnetic attraction has something to do with spin, can anyone explain this to me?
