Does atomic structure require a magnetic force? I understand that in the world of people it is most appreciated, however, it doesn't seem to have a purpose in the atomic structure.
I am not sure what you mean by "require". However, it is true that atomic structure exhibits the effects of magnetic interactions which imply the existence of magnetic forces within an atom. Some examples of these are spin-orbit coupling and the magnetic hyperfine interaction.
I mean does the absence of the magnet force effect the atomic/chemical structure. Would atoms exist without it? It seems to be a product of other forces(if that's the correct term)
