Steel is preferred for making permanent ...

Steel is preferred for making permanent magnets whereas soft iron is preferred for making electromagnets. Explain.

Text Solution

Verified by Experts

Steel is preferred for making permanent magnets on account of its high permeability and high coercivity. Soft iron is preferred for making electromagnets on account of low retentivity, low coercivity and low hysteresis loss.
