Vedclass · Answer

(A) The core of an electromagnet is designed to concentrate the magnetic flux produced by the current-carrying coil. To achieve this efficiently,the material must have high magnetic permeability,allowing it to be easily magnetized. Additionally,it must have low retentivity so that the magnetism disappears quickly when the electric current is switched off. Therefore,soft iron is commonly used for this purpose because it possesses high permeability and low retentivity.
