Abstract

The innovative concept described herein relates to a magnetic angle sensor system having a rotatable shaft, a permanent magnet coupled to the rotatable shaft, and a magnetic field sensor arranged opposite the permanent magnet, wherein the magnetic field sensor is configured to detect a magnetic field prevailing in its detection region. The magnetic angle sensor system comprises means for reducing and/or compensating for an inhomogeneous stray field component of a per se homogeneous external magnetic stray field.
