摘要

Pair of a first and second flat-type electric coil modules manufactured on a generally flat substrate (21) preferably by means of printed circuit techniques, each of said first and second modules presenting a first distribution (20) of spiral-shaped conductive material constituting a first electrical conductor with an input terminal (26) disposed on one side of said substrate (21), and a second spiral-shaped distribution (20¿) of conductive material constituting a second electrical conductor with an output terminal (27) disposed on the opposite side of said substrate, and said first and second conductors of each of said modules being connected by means of an electrical connection (22) through the substrate (21), so that an electrical voltage connected between the input and output terminals (26, 27) of a coil module will drive a current from a terminal (26) through the first co electrical nductor on one side of the substrate by means of the connection (22) through the substrate and the second electrical conductor on the other side of the substrate to the other terminal (27), characterized in that the first distribution (20) of conductive material in said first electric coil module constitutes a specularly symmetrical version of the first distribution (20) of conductive material in said second electric coil module, the second distribution (20¿) of conductive material in said first electric coil module constitutes a specularly version symmetric of the second distribution (20) of conductive material in said second module of electric coil.
