Magnetic Coercivity (Hcb) Single λ is Oe or A / m 1A / m = 79.6 Oe


Magnetic reverse magnetization, so that the magnetic induction to zero required strength of the reverse magnetic field called the magnetic coercivity (Hcb). However, the magnetization of the magnet is not zero at this time, but the applied reverse magnetic field and the magnetization of the magnet cancel each other out. (External magnetic induction intensity is zero) At this time if the withdrawal of the external magnetic field, the magnet still has some magnetic properties. NdFeB coercivity is generally 10000Oe above.
