摘要
A bipolar magnet as used in magnetic disk drives is characterized by measuring field strength of the magnet along a plurality of radii using a Hall effect sensor which is incrementally indexed across the magnet by a stepper motor. The gap field strength, pole transitions, and null zone can be determined from combinations of the measurements along the plurality of radii.
