Iron gets magnetized faster but loses its magnetism as soon as the inducing magnet is removed. Hence soft iron is said to have high susceptibility but lowretentivity. ... Core in the transformer is made up of soft iron material. Steelis slow to be magnetized but retains the acquired magnetism for a long time
