Abstract

A method for determining the position of a sensor element which is used to measure a magnetic alternating field emitted by at least one generator unit. The sensor element receives a signal. Interference fields, which are the fields arising due to eddy currents generated in electrically conductive objects, are calculated. The eddy currents are calculated based on the alternating field. The position can be corrected based on the signal received in the sensor element.
