Compensation method for differential voltage deviations with varying alignment of a sensor rod of magnetometers in the earth's magnetic field and magnetometer

摘要

For the automatic compensation of differential voltage deviations of magnetic inductors (2,2'), in a magnetometer (1), the deviation is determined by a temporary and variable auxiliary electrical magnetic field at the inductor receiver coils (5) corresponding with the external constant field changes. The auxiliary magnetic fields are generated by a coil (4) at the inductors.
