Patent ID: 7508200

Claim:
A magnetic sensor (MS) for sensing a magnetic stray field (SF) generated by a magnetizable object (SPB) when magnetized and for generating an electrical object signal (U OB ) which depends on the sensed magnetic stray field (SF), comprising a magnetic field generator (WR 1 , WR 2 ) for generating a magnetic main field (H) for magnetizing the magnetizable object (SPB), and cross-talk reduction means for reducing the effect of a cross-talk signal component in the electrical object signal (U OB ) caused by magnetic cross-talk between the magnetic main field (H) and the magnetic stray field (SF), wherein the cross-talk reduction means is arranged for distinguishing a signal property between the cross-talk signal component and the remaining part of the electrical object signal (U OB ) and for generating an electrical output signal (U 0 ).
