PERMANENT MAGNETS used in apparatus often are subjected to demagnetization by current surges or stray fields. This weakens the magnet and changes the adjustment. Magnets usually are stabilized against such demagnetizing forces by partial demagnetization.

Permanent magnet materials recently have been developed with characteristics radically different from those of previous materials, the carbon, cobalt, and chromium steels. In this paper, the essential properties of these new materials are discussed and are compared with the corresponding properties of the older materials.

Abstract In the last few decades, as the energy density of permanent magnets has improved, there has been a large increase in the use of permanent-magnet materials in many nontraditional devices and also in energy-conversion systems such as motors and generators.

An outline is given of the state of the art in permanent magnet technology with a brief discussion of the future perspectives opened up by the new materials. There is a growing demand for better performances associated with the expansion of applications and reduction in prices. The general principles that govern permanent magnet behaviour are discussed
