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.
