Step 3 Paramagnetic substances are magnetized in the magnetic field and their magnetism disappears as the magnetic field is removed so it is not stable. … : 458. paramagnetic, ferromagnetic … Ferromagnetic materials retain some … Diamagnetic, Paramagnetic, and Ferromagnetic Materials. They can retain a magnetic field in the absence of a magnetic field as long as they were once in contact with a magnetic field. (i) Susceptibility - Diamagnetic substances have a susceptibility of a low negative value and it is independent of temperature. Asked by: abraham j a Answer ... Ferromagnetic materials will respond mechanically to an impressed magnetic field, changing length slightly in the direction of the applied field. The effects of diamagnetic and paramagnetic are negligibly small so that materials possessing these weak phenomena are said to be non-magnetic. For example, if a magnet adheres to a steel shelf, the shelf is said to be ferromagnetic. Ferromagnetic materials are the three metals that are always magnetic, like iron. Based on their behavior in a magnetizing field, materials are classified as diamagnetic, paramagnetic, and ferromagnetic substances. If paramagnetic gas is introduced between pole pieces of magnet, it spreads in the direction of the magnetic field. Ferromagnetic Materials: - These are materials in which magnetic dipoles interact in such a manner that they tend to line up in parallel. This effect is known as Faraday's Law of Magnetic Induction. Paramagnetic materials have at least one unpaired electron in the system, but diamagnetic materials have all their electrons paired. Thanks, Decai. In a ferromagnetic material, the individual atoms possess a dipole moment, similar to a paramagnetic material. Ferromagnetic materials have a large, positive susceptibility to an external magnetic field. Ferromagnetism can be explained on the basis of domain theory. Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets.In physics, several different types of magnetism are distinguished. paramagnetic and diamagnetic.
