| Abstract | The widely used 2-magnet, Blackett-type astatic magnetometer cannot be used efficiently for Palaeomagnetic research in laboratories where the ambient magnetic field and its vertical gradient are subject
to constant variations. It is shown that under such conditions, the 3-magnet or "biastatic" magnetometer is theoretically more stable and adequate. Considerations for the design of such an instrument are briefly reviewed and a description is given of
an instrument of this type developed at the Geological Survey of Canada, An important feature of this instrument is that its operation can be carried out automatically. The results obtained in testing the performance of the instrument are
analyzed, |
