The magnetic moment of a system measures the strength and the direction of its magnetism. The term itself usually refers to the magnetic dipole moment. Anything that is magnetic, like a bar magnet or a loop of electric current, has a magnetic moment. A magnetic moment is a vector quantity, with a magnitude and a direction.

The interesting thing though, is the body isn't really magnetic. Hence, the magnetic fields don't really see the body as much, and hence aren't affected like the electric fields are. And because the loop antenna is somewhat the "dual" of the dipole as discussed earlier, the magnetic fields are strong in the near field of the loop antenna.

The most important class of magnetic materials is the ferromagnets: iron, nickel, cobalt and manganese, or their compounds (and a few more exotic ones as well). The magnetization curve looks very different to that of a diamagnetic or paramagnetic material.

theory: magnetic monopoles of same sign repel, opposite signs attract. • Dipole created by two poles of opposite sign and separated by distance l. • If you are close to one of the poles, the field can be though of as originating from a monopole. • Magnetic body can be though of as composed of a bunch of little magnets, or dipoles.

This type of geometry gives the impression of two poles at work; thus, a magnet is a dipole. On the other hand, electric charges that radiate in rippling electric fields are known as monopoles. So, a spinning electron giving rise to a magnetic field can be perceived as an enactment of a magnetic dipole.

Paramagnetic substance are attracted by a magnet very feebly. In a sample of a paramagnetic material, the atomic dipole moments initially are randomly oriented in space. When an external field is applied, the dipoles rotate into alignment with field as shown. The vector sum of the individual dipole moments is no longer zero.

Magnetism is a property of matter and it occurs in different forms and degrees in various Earth materials that act as conductors and insulators. For example, at low temperatures, metallic systems exhibit either superconducting or magnetic order. The degree of magnetism of a substance is due to the intrinsic magnetic dipole moment of its electrons.

Dec 27, 2013· These materials when placed in a magnetic field, becomes weakly magnetized in the direction opposite to that of the applied field. There is no permanent dipole moment in each atom. The induced magnetic moment produced in these materials during the application of the external magnetic field decreases the magnetic induction present in the specimen.

In electromagnetism, permeability is the measure of the ability of a material to support the formation of a magnetic field within itself, otherwise known as distributed inductance in transmission line, it is the degree of magnetization that a material obtains in response to an applied magnetic field. Magnetic permeability is typically represented by the (italicized) Greek letter μ.
