The intrinsic coercivity (Hcj) single λ is Oe or A / m (A / m)
The reverse magnetic field strength required to reduce the magnetization of the magnet to zero, which we call intrinsic coercivity. Intrinsic coercivity is a physical quantity that measures the anti-demagnetization capability of the magnet, and it indicates the coercivity that the magnetization M in the material retreats to zero. In the use of magnets, the higher the coercivity of the magnet, the better the temperature stability.
