摘要： A magnetic detecting circuit has a magneto resistance element which converts a change of magnetism detected into a signal. A plurality of these magneto resistive elements are provided on a plane, and are oriented on the plane in two opposite directions having angles, relative to a bias direction, having substantially equal absolute values. The placement in opposite directions allows the resistance values from the elements to change in approximately the same direction as the object moves, to allow a monotonic change in the bias magnetic field. The change of the bias magnetic field can be detected from the change of resistance values of the magneto resistive elements.
