A total field fluxgate magnetometer

Abstract

A fluxgate magnetometer capable of giving a continuous total-field profile has been developed using a three-axis instrument which does not involve moving parts. A simple method is presented for measuring the three relative angles of the fluxgates when they are not mutually orthogonal, and a procedure is described for transforming the outputs of the fluxgates into orthogonal components and into a value for the total magnetic field.
