A fluxgate magnetometer drive circuit includes a fluxgate inductor that is driven through magnetic saturation by altering voltage pulses. Following each drive pulse, the spurred magnetic energy in the fluxgate is allowed to dissipate by connecting a fluxgate across a fixed reverse voltage. The time for the fluxgate current to decay to zero is measured and is indicative of a magnetic field induced in the torque transducer.
