Question

The $B-H$ curve $\left(i\right)$ and $\left(ii\right)$ shown in the figure is associated with

• A. (i) diamagnetic and (ii) paramagnetic substance
• B. (i) paramagnetic and (ii) ferromagnetic substance
• C. (i) soft iron and (ii) steel respectively
• D. (i) steel and (ii) soft iron respectively

Answer 1

Answer: (C)

From the hysteresis curve of soft iron we know Soft iron has high retentivity and low coercive force therefore the loop (i) is for soft iron and the loop (ii) is for steel.
