Question

define the term hysteresis​

Answer 1

Explanation:

$\huge{\boxed{\boxed{\red{\ulcorner{\mid{\overline{\underline{\bf{hysteresis}}}}}\mid}}}}$

The magnetization of the core is repeatedly reversed by the alternating magnetic field.The resulting expenditure of energy in the core appears as heat and is kept to a minimum by using a magnetic material which has a low hysteresis loss.

Answer 2

Answer:

The phenomenon in which the value of a physical property lags behind changes in the effect causing it, as for instance when magnetic induction lags behind the magnetizing force.
