Abstract
A magnetic field sensor array includes a plurality of sensor segments, each including a plurality of magnetic field sensors. A magnetizing current conductor is situated so as to run in the area of the magnetic field sensors in such a way that elements of the magnetic field sensors may be magnetized. A plurality of parallel-connected half-bridges, each including a high switch pand a low switch n, each include a center tap connection situated between the switches. The magnetizing current conductor is connected to each center tap connection, by means of which the magnetizing current conductor is divided into separately activatable magnetizing segments. Elements of a sensor segment are magnetized in that two switches nand phaving different electrical potentials, or alternatively pand n, of two directly adjacent half-bridges are closed simultaneously. At least one further switch nor por alternatively por nis closed.
