Magnetism and matter

Permanent Magnets and Electromagnets

Commonly steel is used to make a permanent magnet because steel has high residual magnetism and high coercivity.

Electromagnets are made of soft iron because area of hysteresis loop for soft iron is small. Therefore energy loss is small for a cycle of magnetisation and demagnetisation.
