Vedclass · Answer

(A) Electromagnets require materials that can be easily magnetized and demagnetized. Soft iron has high permeability and low retentivity,which makes it easy to magnetize. Additionally,soft iron has low coercivity,meaning it can be demagnetized easily by a small reverse magnetic field. Therefore,both the assertion and the reason are true,and the reason correctly explains why soft iron is preferred for electromagnets.

Assertion $(A)$: Electromagnets are made of soft iron.
Reason $(R)$: Coercivity is small for soft iron.
