Ferromagnetism are atoms that produce a magnet or magnetism
ferromagnetism form a fixed flux and a magnetic field
Err kinda.
What it is to do with is the spin of electrons.
As you know when electrons flow through wire they produce a magentic field (Why? well you need to get a Phd in Chem/Physics for that)
Now if you look at the atomic structure of elements they have electron orbits. in these orbits the electrons spin (it is this spin that is used in Quantum computing). BUT in almost all elements the number of clockwise spins equal the number of anti-clockwise spin
Thus the net field is ZERO or extreamly small.
Iron is different, it has a major imballance in electron spin, so the majority of electrons spin in a given direction, thus all contributing to a magnetic field
