Patent ID: 8203329

Claim:
A calibratable magnetic field sensor for sensing a first and a second spatial component of a magnetic field in a reference point, wherein the magnetic field comprises a first and a second measurement field component and/or a first and a second calibration field component, comprising: a first sensor element arrangement comprising at least a first and a second sensor element for sensing the first magnetic field component, which comprises a first measurement field component and/or a first calibration field component, with respect to a first spatial axis in the reference point; a second sensor element arrangement for sensing the second magnetic field component, which comprises a second measurement field component and/or a second calibration field component, with respect to a second spatial axis in the reference point, wherein the two spatial axes pass along linearly independent position vectors; an excitation line arranged with respect to the first sensor element arrangement so that, when impressing a default current into the excitation line, a pair of different asymmetrical default calibration field components in the first sensor element and in the second sensor element is generated with respect to the first spatial axis.
