Abstract
A magnetometer that senses low level currents flowing in a conductor or wire includes two cores with excitation windings on each core that are connected in series but which are wound in opposite orientations. A periodic alternating current drives the windings. Since the windings are in series but oppositely wound, the current flowing through the windings will produce equal but opposite flux flows in the two cores. A sensing winding is wound around both cores to provide flux profiles. A digital processor analyzes a quiescent flux profile, which is generated when no sense current is flowing through the dual cores, and distorted flux profiles when sense currents are flowing through the dual cores to measure a sense current flowing through the dual cores.
