Vedclass · Answer

(D) For a material to be suitable for a permanent magnet,it must retain its magnetism even after the external magnetic field is removed. $1$. High Retentivity: This ensures that the material remains strongly magnetized after the removal of the magnetizing field. $2$. High Coercivity: This ensures that the magnetization is not easily destroyed by stray magnetic fields,temperature fluctuations,or minor mechanical impacts. Therefore,materials for permanent magnets must have both high retentivity and high coercivity.
