Abstract
A magnetic sensor is provided with a permanent magnet that has a beveled surface at one end of the magnet. The beveled surface intersects a first pole face at a preselected angle. The permanent magnet is associated with a magnetically sensitive component that comprises first and second magnetoresistive elements. Both of the magnetoresistive elements comprise two magnetoresistors. The four magnetoresistors are connected in electrical communication with each other to form a Wheatstone bridge that provides an output signal representative of the magnetic field strength in the sensing plane of the magnetically sensitive component. The beveled magnet provides a magnetic field which relates to a magnetically sensitive component in such a way that the position of a magnetic null in the sensing plane is advantageously affected.
