soft iron and steel respectively

Vedclass · Answer

(C) The $B-H$ curve (hysteresis loop) for soft iron is narrow,indicating low retentivity and low coercivity,which means it is easily magnetized and demagnetized.In contrast,the $B-H$ curve for steel is wider,indicating higher retentivity and higher coercivity.Looking at the figure,the loop $S_1$ is narrower than the loop $S_2$.Therefore,loop $S_1$ corresponds to soft iron and loop $S_2$ corresponds to steel.

The $B-H$ curves $S_1$ and $S_2$ in the adjoining figure are associated with:
