Q177 / 180 · COMEDK 2014 · Physics

Electromagnets are made of soft iron because soft iron has

A
low susceptibility and low retentivity
Correct answer
B
high susceptibility and low retentivity
C
high susceptibility and high retentivity
D
low susceptibility and high retentivity

Solution

Electromagnets are made of soft iron because soft iron has a very high value of susceptibility and low retentitivity.

Hence, the correct answer is option: 'B'.
