Patent ID: 8450900

Claim:
A coil, comprising: a coil former defining a coil axis and having an inner side, a base surface, and a cover surface spaced from the base surface, wherein the base surface and the cover surface extend substantially perpendicular to the coil axis; and a first winding layer formed by wire turns wound on the coil former and extending essentially parallel to the coil inner side, and a second winding layer disposed on the first winding layer and being-shorter along the coil axis than the first winding layer, the second winding layer having a first end proximate to one of the base surface or the cover surface and a second end distal from the base surface or the cover surface, said second winding layer being subdivided along its length into two winding segments separated by a gap, wherein the gap is sized to receive a wire from the first winding layer at a wire jump, with the wire retained in the gap and forming a support turn, wherein the coil is a current-carrying coil having a main magnetic field direction extending parallel to the coil axis.
