Abstract
An arrangement is provided for measuring the field strength of a magnetic field, or measuring field, by an angle sensor. The angle sensor is aligned with the field lines of the measuring field at the position of the field strength of the measuring field, or measuring position. A device for generating a magnetic auxiliary field at the measuring position is also included. The angle sensor can be impressed with the magnetic auxiliary field in a predeterminable field strength and in a direction deviating from that of the field lines of the measuring field at the measuring position, forming a resultant magnetic field with a field line direction. The field line direction is measured by the angle sensor as a measure of the field strength of the measuring field. The arrangement is reliable, suitable for measuring high magnetic field strengths, has no reactive effects, and permits measurements with magnetoresistive angle sensors.
