Soft iron is used to manufacture electromagnets because their

magnetic saturation mit is high while retentivity and coercive force are small

retentivity is high but coercive force is small

retentivity is small but coercive force is high

area of hysteresis loop is large.

Verified by Experts

The correct Answer is:

The maderia used for making an electromagnet should possess high retentity and low coercivity. This is satisfied by soft iron.
