Abstract
Magnetic circuit comprising a gap bridging element made of a non-magnetic metal and a wound magnetic core comprising a plurality of stacked concentric ring layers of magnetic material having a high magnetic permeability. The magnetic core has a gap extending through a section of the stacked concentric ring layers of magnetic material, wherein the bridging element is welded to a lateral face of the wound magnetic core on either side of the gap. Welding connections between the bridging element and the magnetic core extend across the stacked concentric ring layers.
