Method of stabilising a magnetometer signal and stabilised magnetometers

摘要

The magnetometer includes a magnetic core (1) with at least one branch (2, 3), at least one exciting coil (4, 5) and one take-up coil (10) sensitive to ambient fields thanks to the excitation field (B). An additional magnetic field, to advantage perpendicular to the previous ones, is added to eliminate very low frequency noises, without it being measured.
