It is strange that the material magnetization is in linear proportion to external field because I see a positive feedback:
Honestly, I do not distinguish very well between B, H and M but I know that the current applied to a ferrite core polarizes its domains increasing some magnetic field (which of the three?).
The external field orientates the atoms. This increases the magnetic field, and, in turn, the increased field forces more and more atoms to align. The process goes on until saturation - all molecules end up in line. So, which force resists the alignment development ensuring the linearity? I suspect that this force must be elastic like the Hooke's law.
