*I hope that I am not embarrassing myself by posting this question in the wrong category; again*(its about photons)
I am assuming that electromagnetism and magnetism are the same thing. Are they?, if no why are they different?
1) What are magnetic field lines made of?
2) When 2 magnets interact would there be an exchange of photons between them?
3) If there is nothing there to interact with the magnet, (lets say we had placed it in a certain place in space where there is no electromagnetic force or gravity) , will there still be photons surrounding the magnet?
4) And lastly! why we don't see light around a magnet?...
I had posted a similar question earlier , but I got no response
