a magnetic field generated with the aid of second induction coil 135 also changes with the alignment of the second induction coil fig3 shows another direction control system 300 for charging device 100 from fig1 as with charging device 200 from fig2 charging device 300 from fig3 is configured to provide an alternative attachment of second induction coil 235 to first carrier 140 of charging device 100 from fig1 and to simultaneously permit a change in the alignment of magnetic field 130 which may be generated by second induction coil 135 a specified cartesian coordinate system corresponds to the coordinate systems in fig1 and 2 direction control system 300 includes a platform 305 similar to platform 205 platform 305 however having a rigid design subcoils 310 through 320 whose alignments differ from each other are situated on the upper side of platform 305 in the illustrated specific embodiment the three subcoils 310 through 320 are inclined toward each other in such a way that axes each of which runs perpendicularly through individual subcoils 310 through 320 intersect above platform 305 at a point on the z axis in other specific embodiments subcoils 310 through 320 may also have other relative alignments or arrangements each of subcoils 310 through 320 is configured to generate a magnetic subfield the generated subfields being superimposed on each other to form magnetic field 130 in the area of coupling surface 110 which is not illustrated above platform 305 depending on the relative alignment of subcoils 310.
