I can't get it imy head why are electrons set in motion in magnet fild - that changes, or why do they move in not strait motion in stady magnetic fild. I know about Lorentz force, but i dont know why, and why that specific direction? I've tryed to correlate it to electrons magnetic fild and spin, but i haven't ended with conclusion, i just need an explanation. Plus to me, moving through magnetic fild (conducter like in generators), do not seems same as standing still, and changing magnetic fild ? p.s. what is particle that carries magnetic fild ? Photon maybe, but it can't be it goes in non starit lines (certainly not photon i'm seening when i'm looking in this screen :) ) p.s.s. does gravitation attratcts magnetic field ?
