Abstract
A magnetometer is provided for detecting the intensity of a present magnetic field. The magnetometer includes a sample having a known resonance frequency response. A first source is provided for applying a first oscillating magnetic field having a first frequency to the sample. A second source is provided for applying a second oscillating magnetic field having a second frequency to the sample in a direction substantially transverse to the first oscillating magnetic field. A receiver is provided for detecting a frequency response output from the sample which is dependent upon the intensity of a present magnetic field so as to measure the intensity of the present magnetic field.
