Solution

The correct option is A High susceptibility and low retentivity
Electromagnetic are made of soft iron because soft iron has High susceptibility and low retentivity.
Electromagnets are made of soft iron because: Soft iron has high retentivity- When the magnetising field is reduced to zero, soft iron retains magnetisation. and Low coercive force-To demagnetise the soft iron, a small force is required
