Paramagnetic materials do not retain their magnetization unlike many (but not all) ferromagnetic materials. To make a magnet you must have residual magnetization and that's generally only ferromagnetic materials. read more
Paramagnetic materials do not retain their magnetization unlike many (but not all) ferromagnetic materials. To make a magnet you must have residual magnetization and that’s generally only ferromagnetic materials. An example is liquid oxygen which is paramagnetic - thus it is attracted to magnetic fields and induces magnetization but those effects disappear the moment the external field is removed. read more
The external magnetic field induces in the atoms of a diamagnetic material a current, which produces a magnetic field in the opposite direction (Lenz's law). Because of this effect, the diamagnet is repelled away. read more
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. read more
