Why cannot we make permanent magnets from paramagnetic materials?

for making a permanent magnet after magnetizing the material the magnetization should remain should retain to a large extent even when the magnetic field is removed(retentivity should be large)


Also the magnetization should not be easily destroyed even if the material is exposed to stray magnetic fields(coercive force should be large)


Paramagnetic materials do not retain their magnetization unlike ferromagnetic materials. When they are placed in external magnetic field after getting magnetized, they lose their magnetization easily and hence have low retentivity.


Therefore, paramagnetic materials are not used in making permanent magnets.
