Question # 1
What is meant by hysteresis loss?
- Ans 1: The area of the loop is the measure of the energy needed to magnetize and demagnetize the specimen during each cycle of the magnetizing current.This is energy required to do work against internal friction of the domains,this work is dissipated as heat.It is called hysteresis loss.
