Vedclass · Answer

(C) Electromagnets are designed to be easily magnetized and demagnetized. Soft iron is chosen for the core of electromagnets because it possesses low retentivity and low coercivity. Low retentivity ensures that the material does not retain significant magnetism when the current is switched off. Low coercivity ensures that the material can be easily demagnetized by a small reverse magnetic field. Thus,soft iron is an ideal soft magnetic material for this purpose.
