Abstract
Apparatus for polarizing a multipole permanent magnet having a main surface is disclosed. The apparatus includes a support member for supporting the magnet; and conductive tubular elements in the form of a coil, the tubular elements being mounted on the support member in relation to the magnet so that the tubular elements produce a magnetizing field across the surface of the magnet to polarize such magnet when the tubular elements are energized. The apparatus further includes circuitry for energizing the tubular elements to produce the magnetizing field to polarize the magnet, and a structure for circulating coolant through the tubular elements to limit the heat build-up of the tubular elements when the tubular elements are energized.
