The unit of coercivity is either Oe or A/m, with 1A/m=79.6Oe. Coercivity is divided into magnetic induced coercivity (Hcb) and intrinsic coercivity (Hcj).
1. Magnetically induced coercivity
When an electromagnetic field is magnetized in the opposite direction, the value of the magnetic induction intensity in the opposite direction required to reduce the magnetic induction intensity to zero is called magnetic coercivity. But at this time, the magnetization of the electromagnetic field is not zero, but the strength of the applied reverse magnetic field and the magnetization of the electromagnetic field complement each other. When the external magnetic induction intensity is zero, if the external electromagnetic field is removed, the electromagnetic field still has certain magnetic properties.
2. Intrinsic coercivity
The reverse magnetic induction required to reduce the magnetization of the magnet to zero is called intrinsic coercivity. The intrinsic coercivity is a physical quantity that measures the ability of electromagnetic field to resist demagnetization, and it is the coercivity that indicates that the magnetization M in the raw material recedes to zero. In the use of electromagnetic fields, the greater the coercive force of the electromagnetic field, the better the environmental temperature stability.
