Abstract
A method for compensating mechanical stresses in measuring the magnetic field strength by Hall sensors is disclosed. It is proceeded in a manner that the electric resistance and/or a measuring quantity proportional to the electric resistance of the Hall sensor is determined in at least two different directions, that the mean value of the determined resistances and/or measuring quantities proportional thereto is calculated, and that the current conducted through the Hall sensor is chosen to be proportional to the mean value calculated.
