| coercivity (ˌkəʊɜːˈsɪvɪtɪ) | |
| —n | |
| Compare coercive force the magnetic-field strength necessary to demagnetize a ferromagnetic material that is magnetized to saturation. It is measured in amperes per metre | |
| coercivity (kō'ər-sĭv'ĭ-tē) Pronunciation Key
The magnetic flux density needed to reduce the magnetization of a material (especially a ferromagnetic material) from complete saturation to zero. Coercivity is measured in teslas. Compare remanence. |
