Abstract (en)
[origin: WO2004013645A1] Disclosed is a magnetic field sensor for measuring at least one component of a magnetic field, comprising a ferromagnetic core (4) used as a magnetic field concentrator, an excitation coil (3), and a readout sensor (5). Preferably, the readout sensor (5) is provided with two sensors that are arranged near the outer edge of the ferromagnetic core (4) and measures the at least one component of the magnetic field. The ferromagnetic core (4) is ring-shaped. The excitation coil (3) is temporarily impinged upon by a current when the magnetic field sensor is operated in order to bring the ferromagnetic core (4) into a state of predetermined magnetization.
