Question # 1

Define Saturation and Remanence of Hysteresis Loop.

  • Ans 1: Saturation: The material is said is reduced to magnetically saturated when magnetic flux density reaches a maximum value.
    Remanence: When the current is reduced to zero,the material still remains strongly magnetize.It is due to the tendency of domains to stay partly in line,once they have been aligned,It is called remanence or relativity.

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.
