Abstract

A device for detecting a position of a position indicator includes an electrical magnetic field source, a sensor and an evaluator. The electrical magnetic field source is configured to generate a magnetic field when an electrical current flows through the electrical magnetic field source. The sensor is configured to detect the magnetic field and provide sensor signals based on the magnetic field detected, the sensor having at least two sensors each of which is configured to detect a spatial direction component of the magnetic field and output a signal corresponding to the spatial direction component. The evaluator is configured to receive the sensor signals and determine the position of a position indicator based on the sensor signals when the magnetic field in the surroundings of the electrical magnetic field source is influenced by the position indicator.
