coercivity

[ koh-er-siv-i-tee ]

noun

, Electricity.

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

coercivity

/ ˌkəʊɜːˈsɪvɪtɪ /

noun

1. 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

coercivity

/ kō′ər-sĭv′ĭ-tē /

1. 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.
2. Compare remanence

Word History and Origins

Origin of coercivity¹

First recorded in 1895–1900; coercive + -ity

Example Sentences

If required for permanent magnet making, it should have the highest possible coercivity combined with a high retentivity.
