Abstract
A system includes a magnet, a first magneto-resistive sensing element, and a second magneto-resistive sensing element. The magnet is configured to provide a magnetic field having a substantially non-diverging magnetic field line and diverging magnetic field lines. The first magneto-resistive sensing element is situated in the magnetic field. The second magneto-resistive sensing element is situated in the magnetic field. The first magneto-resistive sensing element is intersected at a centerline of the first magneto-resistive sensing element by the substantially non-diverging magnetic field line. The second magneto-resistive sensing element is intersected by only the diverging magnetic field lines of the magnetic field.
