    • A temperature stabilized flux-gate magnetometer including a core (12), preferably of ferromagnetic material, having a non-linear magnetization curve, an excitation winding (14) operatively associated with the core (12), an oscillator providing an AC excitation signal to the excitation winding (14) and a signal winding (16,18) operatively associated with the core (12) and providing an AC output signal generally proportional to the ambient magnetic field at the location of the core (12). The flux-gate magnetometer also includes apparatus for extracting from the AC output signal a magnetic field dependent DC signal, apparatus for feeding back the magnetic field dependent signal to the signal winding (16,18) in order to generate at the core (12) a magnetic field substantially opposite in sense and substantially equal in magnitude to the ambient magnetic field and apparatus for sensing a characteristic of the magnetic field dependent signal to provide an output indication of the ambient magnetic field at the core (12).
