Abstract:
A continuous conductive coil element comprising a continuous conductive strip including:a first terminal; a second terminal; a conductive path between the first and the second terminal, wherein the conductive path comprises an arrangement of conductive regions linked together in series by a connector region between each conductive region, and wherein: if the conductive region has a single turn, the turn in that conductive region is connected to an adjacent conductive region in the series by a connector region, and if the conductive region has two turns, the turns in that conductive region are connected to each other by a foldable hinge region; and wherein if two adjacent turns in the series are connected by a connector region, a current travels around each turn in the same direction, and if two adjacent turns in the series are connected by a foldable hinge region, a current entering the two-turn conductive region travels in opposite directions in a turn on each side of the foldable hinge region.
