Industrial magnets

The most familiar of the C-frame, matrix-type industrial magnetic separators are the Carpco, Eriez, Readings, and Jones devices. The Carpco separator employs steel balls as a matrix, Eriez uses a combination of expanded met matrices, and the Readings and Jones separators have grooved-plate matrices. Capacities for this type of unit are reported to up to 180 t/h (in the case of Brazdian-hematite processing). 

Rare metal easily magnetized and used in the alloy alnico to make industrial magnets its isotope cobalt-60 produces radiation that is a treatment for cancer. 

Sintered magnets based on the Nd2Fei4B phase are the most important material for industrial magnetic applications. The most important applications are voice-coil motors (VCM) for hard disk drives, CD/MD pick-up systems, magnetic resonance imaging (MRI), and more recently motors for the electrical vehicle (EV) (Hirosawa and Kaneko 1998).

If p- is measured in ohm-centimeters and i in amperes per square centimeter, then the power density of resistive losses has the units of watts per cubic centimeter. Values of pj of the order of lOw/cm are encountered in typical industrial magnet designs, Generally speaking, p is independent of current density but may vary with position in the coil for reasons which will be discussed later. Therefore, in the typical case where the current density has the same value throughout the magnet, we have...
