Abstract
A system and method for magnetizing a ferromagnetic element is disclosed. Electrodes are positioned on opposite surfaces of the ferromagnetic element and a current is applied to the electrodes, resulting in the formation of a magnetically conditioned region on the ferromagnetic element. Magnetic field sensors may be placed proximate the magnetically conditioned region. Output signals from the magnetic field sensors may be indicative of a load or torque applied to the ferromagnetic element.
