Much airborne magnetic surveying was carried out using fluxgate detectors between 1945 and 1985, and hand-held portable devices were used for making vertical-component ground measurements between 1965 and 1985. A schematic of the fluxgate magnetometer is shown below.

The fluxgate magnetometer was originally designed and developed during World War II. It was built for use as a submarine detection from low-flying aircraft. Today it is used in conducting magnetic surveys from aircraft and for making borehole measurements. ... A schematic of the fluxgate magnetometer is shown below.
