Coercivity meaning

kōər-sĭvĭ-tē
The magnetic field intensity needed to reduce the magnetization of a ferromagnetic material from complete saturation to zero, usually measured in teslas.
noun
The magnetic intensity, usually measured in oersteds, needed to completely demagnetize a substance that has been fully magnetized.
noun
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.
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.
(uncountable) The quality of being coercive.
