coercivity

How strongly a magnetic material keeps its magnetism when a magnetic field tries to change it
  • noun
  • /koʊˈɜːrsɪvɪti/
  • Specialized
: coercitividad
  • (Coercivity is the strength of the applied magnetic field needed to permanently change the direction of the magnetization of a material.)

Examples

  • That approach offers a better combination of coercivity, grain size, and thermal stability than can be achieved with single-layer media; it thus allows higher-density recording.

    Academic text (2002)
  • The coercivity of a magneto-optic material remains high until it has almost reached the Curie temperature.

    Academic text (1996)
  • This may adversely affect the recording performance from low coercivity and poor signal-to-noise ratio.

    Academic text (1996)
  • In short, HMR works by leveraging high coercivity media and localised plasmonic heating.

  • The magnetic film, a cobalt alloy with chromium and coercivity-controlling elements such as platinum or tantalum, is sputtered next.

    Academic text (1996)
  • The coercivity of certain magnetic materials enhances their stability in electronic devices under varying conditions.

  • Engineers test the coercivity of magnets to ensure they maintain their magnetization in strong external fields.

  • High coercivity materials are essential for developing reliable data storage systems that withstand magnetic interference.

Morphology

coercivity = coercive (opaque) = coerce + ive + ity

The noun is regularly formed from the adjective 'coercive' by adding the abstract-noun suffix '-ity'.

Etymology

The word coercivity comes from coerce, which means 'to force', and the ending -ivity that names a quality. Think of a magnet as stubborn when someone tries to make it change, so coercivity is the magnet's power to resist being forced to change its magnetic state.
