Vedclass · Answer

(C) An electromagnet requires a material that can be easily magnetized and demagnetized. $1$. High retentivity allows the material to acquire a strong magnetic field when current flows through the coil. $2$. Low coercivity ensures that the material loses its magnetism quickly when the current is switched off,allowing for efficient control. Therefore,materials like soft iron are ideal for electromagnets because they possess high retentivity and low coercivity.
