A coil arrangement with three windings arranged coaxially, where the outer coils are connected in series. The inductances of the outer coils are of equal magnitude and their magnetic fields have opposing polarities. The center winding induces currents in the series circuit of the outer windings which cancel each other out. The outer windings with their stray inductances form a coil which is separated from the center one and can be applied for other purposes.
