Claim One:
1. A magnetic field sensor device for determining two or three components of a magnetic field, comprising at least one Wheatstone bridge with two half-bridges, each half bridge comprising at least two bridge resistors and at least one of the two bridge resistors being a magnetic field-sensitive resistor with regard to a magnetic field component located in an X/Y magnetic field sensor plane, a ferromagnetic flux concentration element being arranged symmetrically between the two magnetic field-sensitive bridge resistors which, with regard to a Z magnetic field component oriented perpendicular to the X/Y magnetic field sensor plane, generates antisymmetric magnetic field components located in the X/Y magnetic field sensor plane, wherein the circuit arrangement of the bridge resistors or the supply voltage of at least one half-bridge is individually switchable and/or at least one of the magnetic field-sensitive bridge resistors have a switchable resistance characteristic curve, so as to enable switching of at least one resistance characteristic curve, in particular switching in pairs of the resistance characteristic curves of mutually associated magnetic field-sensitive resistors of the two half-bridges or switching of the circuit arrangement of the bridge resistors in at least one half-bridge, wherein in a first state n X/Y-located magnetic field component is measurable and in a second state a magnetic field component located in the Z direction is measurable.
