The aerial versions of these magnetometers suffer from relatively high background noise. The type of magnetometer discussed in this paper has solved the two problems of discontinuity of measurements and reduced sensitivity due to background noise. Comparative texts with an established flux‐gate apparatus have given significant and convincing results., UL https://www.earthdoc.org/content/journals/10.1111/j.1365-2478.1965.tb01921.x
