Abstract
Methods and apparatus for a magnetic sensor including an elliptical magnet to generate substantially circular concentric zones of similar flux density in a plane over and parallel to a surface of the magnet. The sensor can include a sensing element disposed a selected distance from the magnet and a substrate containing circuitry to process a signal from the sensing element to provide a sensor output.
