Explanation
The magnetic field value at the intersection of the saturation magnetic hysteresis (B-H loop) of ferromagnetism and ferrimagnetism materials and the abscissa. The intersection point on the M-H loop is called the intrinsic coercive force, and its unit is A/m. Its physical meaning is that when the material is saturation magnetization, its magnetic induction intensity is not zero after the external magnetic field is removed due to hysteresis, and the reverse magnetic field required to completely demagnetize the material (B=0 or M=0).
