ABSTRACT:
Method and means for coupling an elongated magnetic device such as a "Wiegand" wire to a magnetic circuit comprising the steps of shaping the ends of an elongated magnetic device to provide a high ratio of surface area to volume and a contact surface at each end, and connecting the contact surface of each end of said magnetic device to a conforming portion of a respective one of a pair of spaced ends of a flux conductive means to provide a magnetic path through said conductive means and magnetic device. The ends of the magnetic device are shaped by being compressed to provide flat surfaces on opposite sides and are connected by electric welding, clamping, soldering or adhering same with the flux conductive means. In one form the conductive means is provided with a shunt path for magnetic flux for reducing the reluctance of the coupling means, and controlling the proportion of magnetic flux passing through the elongated magnetic device.
