Abstract
A permanently magnetized magnet associated with the bearing provides a magnetic field which is detected by a detector in the bearing. The relative rotation of one part of the bearing, such as a rotatable shaft or rotatable race, with respect to a second part of the bearing, such as a race, is indicated by the detector.
