Coercive Magnetic Force Automatic Measuring Instrument

Coercive force refers to the magnetic induction intensity B of a magnetic material that does not return to zero when the external magnetic field returns to zero after saturation magnetization. Only by adding a magnetic field of a certain size in the opposite direction of the original magnetizing field can the magnetic induction intensity return to zero. This magnetic field is called the coercive magnetic field, also known as the coercive force.
