What are the different types of magnetism?
Magnetism:
A physical phenomenon caused by magnetic fields. A force that might also attract or repel items that have magnetic properties, such as iron, is known as magnetism.
Types of magnetism:
There are five types of magnetism are follows:
1. Diamagnetism - A magnetism characterized by materials that correspond at right angles toward a non-uniform distribution magnetic field and partially expel the magnetic field in which they have been positioned from their interiors. A diamagnetic substance is one whose atoms have no permanent magnetic dipole moment.
Consider the figure shown above. We have a diamagnetic substance placed in an external magnetic field. We see that the field lines get repelled by the material and the field inside the material is reduced. If we place this substance in a non-uniform magnetic field, it tends to move from the point of a high electric field to that of a low electric field.
2. Paramagnetism - Paramagnetism is the magnetic state of an atom with one or even more unpaired electrons. In a paramagnet, magnetic moments tend to be randomly orientated due to thermal fluctuations when no magnetic field exists. In an applied magnetic field these moments start to align parallel to the field such that the magnetization of the material is proportional to the applied field. This can be illustrated in the diagram below.
3. Ferromagnetism - Ferromagnetism is a physical phenomenon whereby some materials, such as iron, attract one other aggressively. The magnetic moments in a ferromagnet have the tendency to become aligned parallel to each other under the influence of a magnetic field. However, unlike the moments in a paramagnet, these moments will then remain parallel when a magnetic field is not applied. This can be illustrated in the diagram below.
4. Anti-ferromagnetism - Anti-ferromagnetism is a kind of magnetism wherein the magnetic moments of adjacent atoms are antiparallel. Adjacent magnetic moments from the magnetic ions tend to align anti-parallel to each other without an applied field. In the simplest case, adjacent magnetic moments are equal in magnitude and opposite therefore there is no overall magnetization. This can be illustrated in the diagram below.
5. Ferrimagnetism - Magnetism in which magnetic moments possess oppositional moments, akin to anti-ferromagnetism is called ferrimagnetism. The aligned magnetic moments are not of the same size; there is more than one type of magnetic ion. An overall magnetization is produced but not all the magnetic moments may give a positive contribution to the overall magnetization. This can be illustrated in the diagram below.
