词汇 coercivity
释义

Definition of coercivity in English:

coercivity

noun ˌkəʊəˈsɪvɪtiˌkōərˈsivədē
mass nounPhysics
  • The resistance of a magnetic material to changes in magnetization, equivalent to the field intensity necessary to demagnetize the fully magnetized material.

    Example sentencesExamples
    • Magnetic stripes are defined by coercivity, or how densely the magnetic particles are packed into the stripe.
    • The straightforward remedy is to adopt magnetic materials of higher coercivity, meaning they are harder both to magnetize and to demagnetize.
    • The coercivity of haematite exceeds that of magnetite, and hence this technique is of little use on haematite-dominated magnetizations.
    • A fundamental challenge researchers are facing is that high media coercivity is normally associated with an increased difficulty in writing.
    • To enable increased bit and track densities, media manufacturers have used increasing coercivity for every successive generation of tape products.
