2 Terms for Magnetic Materials and Components

2.1 Basic Terms
221-01-01 Magnetic field
That component of an electromagnetic field which is characterized by the magnetic field strength vector H and the magnetic flux density B (see IEV Chapter 121). (See 121-11-69)
221-01-02 Elementary magnetic dipole
Magnetic dipole provided with atomic or molecular scale in directed plane current loop.(See 121-11-48)
221-01-03 Magnetic dipole
An entity which, in terms of its magnetic field at all points at distances sufficiently large compared with its dimensions, can be replaced by a plane current loop. (See 121-11-47)
221-01-04 Saturation magnetization
Ms
The maximum obtainable magnetization for a given substance at a given temperature.
221-01-05 Saturation magnetic polarization
Js
The maximum obtainable magnetic polarization for a given substance at a given temperature.
221-01-06 Saturation magnetization (mass) density
Specific saturation magnetization
σs
The saturation magnetization divided by the mass density.
221-01-07 Magnetic dipole moment
js
A vector quantity given by the volume integral of the magnetic polarization for the substance of a region. (See 121-11-55)
