Ferromagnetic materials are those magnets that shows spontaneous
magnetization. If these materials are brought closer to a magnet they
will be strongly attracted towards it regardless of orientation. Some of
the ferromagnetic Materials along with their curie temperature are: Co,
Fe, FeOFe2O3, MnBi, Ni, MnSb, Gd, Dy, EuO etc.
Diamagnetic materials are those materials that exhibits magnetism in
the presence of an externally applied magnetic field. When the orbital
motion of electrons of any element changes it result in diamagnetism.
When the magnetic field is applied the force generated by the field
results in the speeding up or slowing down of electrons. This result in
the changing of the magnetic moment of the orbital in a direction
opposing the external field. Diamagnetic materials repel the magnetic
Paramagnetic materials exhibit magnetism when the external magnetic
field is applied. Paramagnetic materials loose magnetization in the
absence of an externally applied magnetic field. These materials are
weakly attracted towards magnetic field.
