Intrinsic coercivity is a physical quantity to measure the ability of a magnet to resist demagnetization. It is the coercivity of magnetization intensity M in a material to fall to zero.
Different from the coercive force, when the reverse magnetic field H = Bc, although the magnetic induction intensity B of the magnet is 0, the magnet does not show magnetic flux to the outside, but the vector sum of the microscopic magnetic dipole moments inside the magnet is often not 0, and also That is to say, at this time, the magnetic polarization of the magnet tends to maintain a large value in the original direction.
Therefore, Hc is not enough to characterize the intrinsic magnetic properties of the magnet; when the reverse magnetic field H increases to a certain value Hcj, the vector sum of the microscopic magnetic dipole moments inside the magnet is 0, and the reverse magnetic field H is called the value of The intrinsic coercivity Hcj of the material.
Note: The intrinsic coercivity is closely related to the temperature stability of rare earth permanent magnets. The higher the magnet coercivity, the better the temperature stability.
