Introduction of magnetization curve
The magnetic material in the magnetically neutral state will increase with the increase of the magnetic field strength H under the action of the magnetic field, and finally reach the saturation magnetization value Ms at a certain saturation magnetic field strength Hs. At this time, the material inside Atomic magnetic moments have basically been oriented along the magnetic field, and then increase the magnetic field strength, the magnetization value will not increase significantly. The corresponding curve drawn on the M-H diagram with the change of the magnetization intensity with the magnetic field intensity is called the magnetization curve, also called the initial magnetization curve. Correspondingly, the curve of the magnetic induction intensity B of the magnetic material changing with the magnetic field intensity H is called B-H magnetization curve.
