A receiving device for receiving a magnetic field and for producing electric energy by magnetic induction. The receiving device includes at least one coil of at least one electric line. The magnetic field induces an electric voltage in the at least one coil during operation. The receiving device and the at least one coil are adapted to receive the magnetic field from a receiving side of the receiving device. The receiving device includes a field shaping arrangement including magnetizable material adapted to shape magnetic field lines of the magnetic field. The field shaping arrangement is placed behind the at least one coil. A depth of the field shaping arrangement varies. A method of manufacturing a receiving device and an arrangement including the receiving device.
