coercivity
[ koh-er-siv-i-tee ]
noun
- 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
- 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 /
- 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

Example Sentences
In response, Apple says: "Smartphones and other items contain magnets or components that may have a risk of demagnetizing low coercivity cards. To prevent this from happening, users should keep these cards stored separately."

Such simulations have shed light on microstructural features that hinder the coercivity, which quantifies a magnet's resistance to demagnetization in opposing magnetic fields.
Micromagnetic simulations on the tomography-based models reproduced the coercivity of ultrafine-grained Nd-Fe-B magnets and explained its mechanism.
The microstructural features relevant to the coercivity and nucleation of magnetization reversal were revealed.
