Vedclass · Answer

(A) material used for making a permanent magnet must have high retentivity so that it retains a strong magnetic field after the magnetizing field is removed.It must also have high coercivity so that the magnetic field is not easily destroyed by external magnetic fields,temperature fluctuations,or mechanical vibrations.Steel possesses both high retentivity and high coercivity,making it an ideal material for permanent magnets.
