In the production of electricity, permanent magnets are found at the heart of generators. Despite their ubiquity, however, magnets themselves have not kept pace with demands of higher performance, lighter weight machines. In fact, it has been more than 30 years since the last new magnetic material (NdFeB) became commercially available.

What Is the Difference Between a Permanent Magnet and a ...

Permanent magnets differ from temporary magnets by their ability to remain magnetized without the influence of a nearby external magnetic field. Typically, permanent magnets are made from "hard" magnetic materials where "hard" refers to a material''s ability to become magnetized and remain magnetized. Steel is an example of a hard magnetic material.

Magnetism Wikipedia

Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetized to become permanent magnets ...
