Claim Text:
1. A system, comprising: at least one vehicle; a primary conductor system; and a secondary coil for inductive supply of the vehicle from the primary conductor system; wherein the secondary coil includes a coil core, which has at least one main limb having an axis, the secondary coil being made up of a first and second coil, which are formed of windings which enclose a main limb in each case by winding around the axis, wherein the first coil is arranged such that windings are connected in series, and an induction voltage arising at the first coil corresponds to a sum of individual voltages induced at all windings when a magnetic flux enclosed by an individual winding in the main limb always has a same direction; wherein the second coil is composed of a first type of windings and of a second type of windings, the windings connected in series, and an induction voltage arising at the second coil corresponds to a difference of a summation voltage of all individual voltages induced at the windings of the first type, and to a summation voltage of all individual voltages induced at the windings of the second type, when a magnetic flux enclosed by an individual winding in the main limb always has a same direction, wherein the second coil surrounds the first coil, and wherein the first type of windings of the second coil and the second type of windings of the second coil are wound in opposite directions from each other and connected in series with respect to one another.
