Claim:
1. A device for determining an external magnetic influence comprising: a component comprised of a ferromagnetic material and having a center axis, the component having a magnetizable region comprising at least three magnetic tracks with adjacent magnetic tracks being magnetized in opposite directions of each other, the at least three magnetic tracks being arranged circumferentially and perpendicular to the component center axis; at least two coils of a first magnetic field sensor for emitting a signal, the first magnetic field sensor coils being arranged axially in relation to the component and radially spaced from the component, and being assignable to the first outer and at least one middle magnetic track, respectively; at least two coils of a second magnetic field sensor for emitting a signal, the second magnetic field sensor coils being arranged axially in relation to the component and radially spaced from the component, and being assignable to the at least one middle and second outer magnetic track, respectively; and wherein the signal of the first sensor is configured to be set in relation to the signal of the second sensor.
