Abstract
A sensor system comprises a magnetic field generator and a sensor device arranged at a distance from said magnetic field generator and adapted for measuring or determining at least one magnetic field component and/or at least one magnetic field gradient component. The magnetic field generator comprises a multi-pole magnet having a number N of pole pairs that are axially magnetized to generate an N-pole magnetic field that is substantially rotationally symmetric around an axis. The magnet comprises a plurality of grooves and/or elongate protrusions that are arranged in a rotationally symmetric pattern around the axis to provide a substantially constant magnetic field gradient in a central region around said axis.
