In situ magnetization of isotropic permanent magnets
IEEE Transactions on Magnetics, 2002Summary form only given. Proper magnetization of isotropic permanent magnets is key for their application in motors and other devices. To simplify assembly, it is often preferable to pulse magnetize "in-situ" in a fully or partially assembled device.

The Cycloid Permanent Magnetic Gear
IEEE Transactions on Industry Applications, 2006This paper presents a new permanent-magnet gear based on the cycloid gearing principle. which normally is characterized by an extreme torque density and a very high gearing ratio. An initial design of the proposed magnetic gear was designed, analyzed, and optimized with an analytical model regarding torque density.

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.

Intermetallics for permanent magnets
IEEE Transactions on Magnetics, 1993Going back as far as 1931, it is shown by the examples MnAl, Fe-Nd, Fe-Nd-B, and Fe(-Ti)-Sm how the history of permanent magnet materials might have evolved differently if hints had been heeded that were discernible long before a particular magnet development actually began.

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.
