Abstract
An overview on the physics of hard magnetic materials is given. The basic considerations leading to hard magnetic properties are discussed. All groups of industrial permanent magnets such as: Al-Ni-Co, ferrites. Sm-Co based, Nd-Fe-B are presented. The most important production methods are described. The advantage and disadvantages of each magnet group is given.
