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.

Magnetic circuit with wound magnetic core

An electric current sensor having a housing, magnetic circuit with a magnetic core, and a magnetic field detector with a detection cell, positioned in an air gap between ends of the core. The core is made of a non-laminated magnetic material, and the magnetic circuit has a strap made of non-magnetic material welded to the core at each side of the air gap. The magnetic field detector has a support plate on which the detection cell is mounted. The plate has a recess, opposition the detection cell, which houses one end of the magnetic circuit.
