Abstract
A method is disclosed for equalizing the electrical resistance of two or more magnetoresistor sensor elements positioned on a permanent magnet in a sensor assembly. The method may utilize a laser to reduce the magnetic field of the portion of the permanent magnet underlying the sensor with the higher electrical resistance.
