%X There are two well known brands of vertical force fluxgate magnetometers presently in use in Australia. Both are manufactured in the northern hemisphere and the circuitry is designed to give positive anomalies over normally magnetised rock units in the northern hemisphere. This follows the convention that magnetic inclination is positive in the downward direction.
