In one embodiment, an integrated magnetometer has a deformable, electrically conducting beam that is mounted on a substrate and adapted to oscillate with respect to the substrate. When the oscillating beam is exposed to a magnetic field, the magnetic field induces an oscillating electromotive force that generates an oscillating electrical signal along the beam. The magnetometer has a detection circuit that detects this oscillating electrical signal and, based on the results of this detection, determines the magnetic-field strength and/or the magnetic-field gradient.
