Abstract

This method of compensation in the measurement of a magnetic field comprises: the determining of a position and of a magnetic moment of an image of the source situated on the other side of the magnetic disturber using one or more measurements of the emitted magnetic field, performed by at least one magnetic sensor whose position and orientation relatively to the source are known, and the subtraction of the magnetic field emitted by this image from the measurement of the magnetic field made by the sensor in the presence of the magnetic disturber to obtain compensation in this measurement.
