Abstract
In determining an exciter conductor spacing of an exciter conductor of an exciter conductor structure from a sensor element of a calibratable magnetic field sensor, first and second electric currents are impressed into the first and second exciter conductors of the exciter conductor structure to generate first and second magnetic field components in the sensor element of the magnetic field sensor, and a quantity is determined depending on the first and second magnetic field components by means of the sensor element. Further, the exciter conductor spacing of the exciter conductor from the sensor element of the magnetic field sensor is established in dependence on an exciter conductor intermediate spacing between the first exciter conductor and the spaced-apart second exciter conductor and the quantities depending on the first and second magnetic field components.
