Vedclass · Answer

(B) An electromagnet must be easily magnetized and demagnetized by the application and removal of an external magnetic field.To achieve this,the material must have low retentivity so that it does not retain magnetism after the current is switched off.Additionally,it must have low coercivity so that it can be easily demagnetized.Therefore,the correct choice is low retentivity and low coercivity.
