Abstract
A magnetic sensor arrangement, comprising: a magnet assembly and a magnetic sensor; the magnet assembly forming a magnetic field having at least two magnetic field components with different angular periodicities at the location of the magnetic sensor and the magnetic sensor including means for sensing the different magnetic field components to produce at least a first and a second sensor element signal; and a computing element for receiving the at least first and second sensor element signals and combining them to produce a unique angular position of the magnet relative to the sensor. A method of determining a unique angular position is also provided.
