How Magnets Work, The history of magnets, Types of magnets, Uses of Magnets and Electromagnetism
The induced magnetic moment produced in these materials during the application of the external magnetic field decreases the magnetic induction present in the specimen. Origin A material contains a large number of electrons and the orbits of these electrons are randomly oriented in space.
Most permanent magnet devices will use soft magnetic materials to channel flux lines or provide a return path for magnetic fields, e.g. MRI body scanners have large permanent magnets with a yoke of soft magnetic material to prevent self demagnetising fields that would reduce the field in the gap of the scanner.

magnetization is given by the magnetic susceptibility of the material χ m, which is commonly defined by the equation. Magnetic materials may be classified as diamagnetic, paramagnetic, or ferromagnetic on the basis of their susceptibilities.

properties to the extrinsic properties, which describe the technical performance of these magnetic materials. This section provides an overview of the magnetic properties of magnetic materials, and in particular of permanent magnets. First, the intrinsic parameters, accepted as the core of magnetic character, will be introduced.
Magnetism, at its root, arises from two sources: Electric current.; Spin magnetic moments of elementary particles.The magnetic properties of materials are mainly due to the magnetic moments of their atoms' orbital electrons.
The idea of using ironresin composites for soft magnetic applications is not new. It appeared more than 100 years ago but ironresin composites have been rarely used because their properties, the processing technology for making parts and real needs for these materials were not sufficiently developed.
