An apparatus for magnetizing selected portions of a shaft in a substantially
circumferential
direction includes a fixture mounted onto the apparatus adapted to receive a shaft
to be magnetized, at least one magnetization head, the magnetization head being
mounted moveably on the apparatus such that the magnetization head can be moved
radially relative to the fixture, a plurality of brushes mounted onto the magnetization
head, each brush having a distal end defining an internal diameter sized to circumferentially
contact the shaft, the brushes being spring-loaded such that when the magnetization
head is moved toward the fixture, each brush engages the shaft with proper pre-load
force, and a buss bar, wherein the brushes are electrically connected to the buss
bar for even distribution of electrical current to the brushes.
