Abstract
A magnet assembly retained on the rotor of a rotary position sensor such as, for example, the drum of a vehicle pedal. The drum of the vehicle pedal includes a retention pocket for the magnet assembly. In one embodiment, the magnet assembly includes a magnet with a pair of spaced apart legs and a pair of pole pieces abutted against the exterior of the legs. Each of the pole pieces includes a plurality of pointed barbs that are pressed into the material of the retention pocket on the drum of the vehicle pedal to retain the magnet assembly on the vehicle pedal.
