- the magnetic intensity needed to reduce to zero the magnetic flux density of a fully magnetized magnetic specimen or to demagnetize a magnet.

- a measure of the magnetization of a ferromagnetic material as expressed by the external magnetic field strength necessary to demagnetize it. Measured in amperes per metreCompare coercivity
- the magnetic-field strength necessary to demagnetize a ferromagnetic material that is magnetized to saturation. It is measured in amperes per metreCompare coercive force
