1. A magnetometer comprising:

  • a resonant sensor for sensing a magnetic field, said sensor generating an output signal having a signal characteristic that varies in response to the sensed magnetic field;

    an excitation circuit coupled to said resonant sensor for supplying an excitation signal thereto, said excitation circuit limits the amplitude of the excitation signal to prevent significant saturation of the response of said resonant sensor to the excitation signal; and

    a processor coupled to receive the output signal from said sensor, said processor determines the magnetic field component sensed by said sensor.
