Question

Electromagnets are made of soft iron because soft iron have : (A) low retentivity and high susceptibility (B) low retentivity and low susceptibility (C) high retentivity and high susceptibility (D) high retentivity and low susceptibility

Tardigrade Admin · Accepted Answer

Soft iron have low retentivity and high susceptibility, due to low retentivity when current starts to flow then immediately it becomes magnet and as current is off, its magnetism vanishes.
