Question

State whether True or False :

Hysteresis is the number of lines of force per unit area in a magnetic field.

• A. True
• B. False

Answer 1

The correct option is B False

Hysteresis 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.ysteresis is the variation of magnetization with applied field and illustrates the ability of a material to retain its magnetization, even after an applied field is removed.
