Electromagnets are made of soft iron because soft iron has
(a) low retentivity and high coercive force
(b) high retentivity and high coercive force
(c) low retentivity and low coercive force
(d) high retentivity and low coercive force
Correct option (c) low retentivity and low coercive force
Explanation:
Electromagnets are made of soft iron because soft iron has low retentivity and low coercive force or low coercivity Soft iron is a soft magnetic material.
