Abstract
The disclosure relates to a magnetometer in which direction of the Earth's magnetic field is determined on the basis of time variant differences in the inductance of a sensor coil of the digital compass which is a function of the orientation of the sensor coil with respect to the Earth's magnetic field. The magnetometer includes a sensing coil, a feedback resistor, and a comparator.
