Diamagnetic, Paramagnetic, and Ferromagnetic Materials. When a material is placed within a magnetic field, the magnetic forces of the material''s electrons will be affected. This effect is known as Faraday''s Law of Magnetic Induction. However, materials can react quite differently to the presence of an external magnetic field.

If you wish to create a permanent magnet you should use a material with a very fat hysteresis loop (figure 5.7a). Such materials, once magnetised, are very difficult to demagnetise and when the magnetising force is removed a substantial magnetic flux density remains. These materials are known as hard magnetic materials.
