The definition of soft magnetic materials starts with this: A soft magnet is not permanent. You can easily magnetize and demagnetize a soft magnet. The magnet you attach to your kid's homework on the fridge is a hard, or permanent magnet. A soft magnet wouldn't work there because it doesn't consistently maintain magnetism.

Magnetic Material. A magnetic material placed in a magnetic field (H) has a magnetic induction (B), measured in teslas (T), expressed by Equation [8.44], where μ0 is the permeability of free space (4π×10−7TmA−1) and the magnetisation, (M=m/V), is the magnetic moment (m) per unit volume (V) of the material (Oberteuf, 1974).

The magnetic properties of materials, worked out on a more advanced level than we have been able to do here, have fascinated physicists of all kinds. In the first place, there are those practical people who love to work out ways of making things in a better way—they love to design better and more interesting magnetic materials.

crystal - crystal - Ferrimagnetic materials: Ferrimagnetism is another type of magnetic ordering. In ferrimagnets the moments are in an antiparallel alignment, but they do not cancel. The best example of a ferrimagnetic mineral is magnetite (Fe3O4). Two iron ions are trivalent, while one is divalent. The two trivalent ions align with opposite moments and cancel one another, so the net moment ...

Magnetic dipoles in these materials are arranged into domains where the arrangements of individual magnetic dipoles are essentially perfect that can produce strong magnetic fields. Normally, these domains are usually randomly arranged and thus the magnetic field of each domain is cancelled by another and the entire material does not show any ...

The magnetics design engineer has three standard words when making the normal design trade-off study: cost, size, and performance. He will be happy to stuff any two into the bag. The magnetics engineer is now designing

Magnetic anisotropy means that the magnetic properties depend on the direction in which they are measured. It strongly affects the shape of the M-H curve. Key phenomenon used in the design of most commercial magnetic materials.

of a sample of material is defined as the total magnetic moment per unit volume. For a homogeneous medium, M is the same everywhere in the sample. Of course, at the edges where the homogeneity is lost, the magnetization will differ from the bulk value. We mentioned the magnetic field or magnetic flux density B above. The unit of B is the tesla (T).
