All material can be classified into ferromagnetism, ferrimagnetism, paramagnetism, diamagnetism, and anti-ferromagnetism according to their magnetism behavior and bulk magnetic susceptibility. Ferromagnetic and ferrimagnetic material can form permanent magnet or be attracted to magnets. Paramagnetic materials are weakly attracted to the permanent magnet. Paramagnetic materials can become very weak magnets under the action of magnetic field and its attractive force can merely detect by sensitive instruments. Diamagnetic materials also exhibit no visible reaction to the external magnetic field. Anti-ferromagnetic solid materials show abnormal behavior under applied magnetic field being dependent upon the ambient temperature. Solid material exhibits no response to the magnetic field at very low temperature, then generate weak magnetism after reached the Néel temperature.
