![]() Examples include ferrites made of magnesium, zinc, and iron. Some materials might entirely lose their ferromagnetism upon heating. These substances emerge when magnetic moments are aligned in both directions (parallel and antiparallel), but in unequal proportions. The examples of such substances include MnO, V 2O 3 etc. This is because their dipole moments are arranged in a compensatory manner. These substances have a net zero magnetic moment. All the electrons in these substances are unpaired and aligned in the same direction. Examples of ferromagnetic solids include cobalt, nickel etc. In an electromagnetic environment, these domains organize and align themselves with the magnetic field. Ferromagnetic substances have distinct groups of metal ions known as "domains." Every domain is comparable to a little magnet. It means they can maintain their magnetic properties even in the absence of external magnetic fields. These solids become permanently magnetized when they are subjected to an external magnetic field. Ferromagneticįerromagnetic substances are strongly attracted by the magnetic fields. Diamagnetic substances behave like an insulator. This is why their atoms have zero magnetic moments. In diamagnetic substances, all of the electrons in the orbital are completely filled and are paired. They do so because the magnetic property that has settled inside of them runs counter to the magnetic fields. ![]() ![]() ![]() Diamagneticĭiamagnetic substances are the substances that are weakly repelled by the magnetic fields. Paramagnetism is created when the magnetic field magnetizes at least one pair of mismatched electrons in their orbit shell. Such substances are weakly attracted by magnetic fields. If a paramagnetic substance is taken out of the magnetic field, it loses its magnetic properties. These compounds exhibit weak magnetization in the presence of an external magnetic field. Based on their magnetic properties, solids are divided into five classes: Paramagnetic Spinning of electrons along their own axis the + and - signs denote the direction of the spin.īecause of these constant movements, the electrons are surrounded by an electric field that resembles a current loop and thus generates magnetic moment.Electrons revolving around its nucleus. ![]()
