A sensor for detecting the direction of a magnetic field in a plane, the direction of which is defined by a polar angle phi, has a number n of magnetic field sensors. A measuring axis is assigned to each magnetic field sensor in such a way that the absolute value of the output signal of the magnetic field sensor is at its greatest when the magnetic field runs parallel to the measuring axis. All measuring axes intersect at a common point. The number k of measuring axes amounts to at least three and an operating mode is foreseen with which for calculation of the angle phi two magnetic field sensors are selected that belong to different measuring axes and the output signals of which in terms of value are less than the output signals of the magnetic field sensors that belong to other measuring axes.
