Abstract
Magnetic field compensation device having a first bar-shaped flux concentrator and a second bar-shaped flux concentrator, wherein the first flux concentrator and the second flux concentrator are separated from one another in a y-direction, and the longitudinal axis of the first flux concentrator and the longitudinal axis of the second flux concentrator are arranged to be substantially parallel to one another. A control unit is in an operative electrical connection with the magnetic field sensor and the compensating coil, and the control unit is equipped to control the compensating current through the compensating coil using a measured signal from the magnetic field sensor in such a manner that, for an external magnetic field formed in the x-direction at the location of the magnetic field sensor, the magnetic field is substantially compensated.
