Abstract
A receiving device for receiving a magnetic field and producing electric energy by magnetic induction. The receiving device includes at least one coil of an electric line. The magnetic field induces an electric voltage in the coil during operation. The coil has an inductance. The receiving device and the coil are adapted to receive the magnetic field from a receiving side. The receiving device includes a case enclosing the at least one coil and further components of the receiving device. The receiving device includes at least one capacitor. The capacitor is electrically connected to the coil or to at least one of the coils so as to form an electric circuit having a resonance frequency according to the inductance(s) of the coil(s) and to the capacitance(s) of the capacitor(s).
