After carefully reading textbooks, research papers and a lot of forums, I find myself more confused than ever regarding the composition of magnetic fields. So please let me ask some (hopefully) very simple questions:
(1) Do we or do we not know exactly how magnetic fields arise and dissipate?
(2) If we do, I want to confirm that they are composed solely of photons as stated by many erudite authors. What distinguishes magnetic photons from other photons? Is it just wavelength/energy or are there other differences between magnetic photons and, say, light photons.
(3) The reason for my inquiry is that I am trying to understand the behavior of magnetic fields. So maybe that can be accomplished even without knowing the answers to the above questions. Apparently, like other photons, magnetic photons exhibit momentum. So if we were to reproduce the old children's toy (a four paddle spinning pinwheel suspended on a needle in a vacuum with one side of each paddle painted black and the other white) using non-magnetic materials, would we be able to see it spinning as well?
(4) In the magnetic field of a bar magnet, do the photons circulating within the field all originate from within the magnet?
(5) If we were to "sink" the north pole of such a magnet, by sticking it onto a very large ferromagnetic surface, like the hull of a ship, would all the photons that enter the south end of the magnet also originate within the magnet, or would other magnetic photons from the Earth's magnetic field flow into the south end of the magnet?
(6) How exactly do magnetic fields interact? If we were to image the magnetic field of a bar magnet, and then place the north end of a second bar magnet in proximity to the north end of the first magnet, would we be able to observe distortions in the field?
(7) Last, can you refer me to a good textbook or other source of knowledge that I can study to get a better understanding of magnetic field interactions?
Thank you all very much in advance for the effort I know you will have to expend in answering these questions. I am grateful.
