Abstract
A fluxgate magnetometer with a linear array of three sensors equi-spaced along a support beam and accurately adjustable into the same spatial orientation for sensing magnetic field anomalies and/or for measuring a single axis component of a magnetic field at two or more points in space. The beam is mounted in an elongate housing provided with pairs of wedges, acting in opposition to one another at opposite ends of the beam, for flexing the beam to adjust the sensors, which have drive windings in containers secured to the beam, the drive windings being rotatably adjustable in their containers relative to sense windings and feedback windings.
