Abstract
A magnetometer with a set/reset coil having portions that cross portions of sensing strips at an angle in order to create a magnetic field in the sensing strip that is at an angle with respect to the easy axis of magnetization of the sensing strip. Each sensing strip may have a portion having a magnetic field created therein that is different from a magnetic field created in another portion of the same sensing strip. As a result, a lower set/reset coil current is needed to initialize the magnetometer.
