It has its own magnetic moment due to presence of unpaired electrons. | It has its own magnetic moment due to presence of unpaired electrons. | All the electron are paired so there is no permanent net magnetic moment per atom. |
Paramagnetic materials have a small, positive susceptibility to magnetic fields. Paramagnetic materials include magnesium, molybdenum, lithium, and tantalum. | Ferromagnetic materials have a large, positive susceptibility to an external magnetic field. Iron, nickel, and cobalt are examples of ferromagnetic materials. | Diamagnetic materials have a weak, negative susceptibility to magnetic fields. Copper, silver, and gold, are diamagnetic. |
