    Soft iron usually as it has properties:- (1) The material should have low retentivity so that it gets demagnetised easily. (2) For the electromagnet to be very strong, it should have a high value of saturation magnetisation. (3) It should have low coercivity . (4) Hysteresis loss should be small. It should not be heated up during magnetisation and demagnetisation. The above-mentioned properties are reasonably met with soft iron and so soft iron is usually preferred for an electromagnet.
