<p>A fluxgate magnetometer sensor for simultaneously measuring, at the same point in space, the three mutually orthogonal components of a magnetic field comprises a ring core 1 of magnetizable material, with a drive winding wound toroidally around the core. A first secondary winding 3 is wound circumferentially surrounding the core. A second secondary winding 4 is wound toroidally over a portion of the core, and a third secondary winding 5 is wound toroidal]y over another portion of the core, preferably at 90 DEG to the second secondary winding. Windings 4, 5 are each split into two sections wound in opposition toroidally over opposite segments of the core. Alternatively 4, 5 may be wound completely and diametrically around the outside of the core (Fig. 2) or the core may be positioned in a non-magnetic cube with windings 3, 4, 5 wound on the outside of the cube (Fig 3). <IMAGE></p> |
