reluctivity

reluctivity

9.9
A measure of how hard it is for a magnetic field to form inside a material
  • noun
  • /rɪˈlʌktɪvɪti/
  • Specialized
translation icon : reluctividad
  • Soft iron has a low reluctivity, making it ideal for transformer cores.

Examples

  • The reluctivity of non-magnetic materials is relatively high compared to ferromagnetic ones.

  • Higher reluctivity indicates greater resistance to magnetic fields.

  • In designing an electromagnet, the reluctivity of each component must be taken into account.

  • The reluctivity of the material affects its magnetic properties.

Surface Forms

reluctivity singular
reluctivities plural

Morphology

reluctivity = reluctance (opaque) = reluct + ivity

Although formally related to 'reluctance', the technical physics meaning ('magnetic resistance') is specialized and not derivable from the everyday sense of 'reluctance'.

Etymology

Reluctivity comes from the same root as reluctant; the old Latin part luct meant 'struggle', so the word gives the idea of 'resist'. In physics, reluctivity measures how much a material 'resists' a magnetic field entering it, so the name fits.
