Question

Write a brief note on Hysteresis effect.

Answer 1

The magnetization of ferromagnetic substances due to a varying magnetic field lags behind the field. This effect is called hysteresis, and the term is used to describe any system in whose response depends not only on its current state, but also upon its past history. The loss of energy per magnetization cycle per volume is given by Steinmetz's equation.
