This section describes the magnetic moment and its use in determining the properties of magnetic materials. The magnetic moment (which is based on a current loop) can be used to model the field around a permanent magnet. Correlations for approximately the magnetic field distribution for a magnetic moment and for a current loop are also presented in this section.
The properties of a magnetic material are described based on magnetization curves, which can be presented in a number of different ways, as listed here. These properties and their relationship to the atomic magnetic moment (Bohr magneton) are explained in this section.
