Soft iron is used in making an electromagnet because (a) It has low permeability (b) It has high coercivity (c) It has high retentivity (d) It has low retentivity

Answer: (d). An electromagnet must lose its magnetism as soon as the current is switched off. Soft iron has low retentivity, low coercivity and high permeability, so it does this well. So the answer is (d) it has low retentivity.
