释义	coercivity co·er·civ·i·ty C0455950 (kō′ər-sĭv′ĭ-tē)n. The magnetic field intensity needed to reduce the magnetization of a ferromagnetic material from complete saturation to zero, usually measured in teslas. coercivity (ˌkəʊɜːˈsɪvɪtɪ) n (General Physics) the magnetic-field strength necessary to demagnetize a ferromagnetic material that is magnetized to saturation. It is measured in amperes per metre. Compare coercive force co•er•civ•i•ty (ˌkoʊ ərˈsɪv ɪ ti) n. the magnetic intensity needed to reduce to zero the magnetic flux density of a fully magnetized magnetic specimen or to demagnetize a magnet. [1895–1900] coercivity coercivity [‚kō·ər′siv·əd·ē] (electromagnetism) The coercive force of a magnetic material in a hysteresis loop whose maximum induction approximates the saturation induction. coercivity On magnetic media, the amount of electrical energy required to change the polarization of a bit. The coercivity of hard disks ranges from 500 to 2,000 Oersted. On magneto-optic media, it takes between 5,000 to 10,000 Oersted. See Oersted. MedicalSeeoersted
