A magnetic core for an electromagnetic induction device has a plurality of magnetic core elements (14). Each of the core elements is formed by winding a plurality of layers of uninsulated strip (18) of magnetically permeable material. The core elements are juxtaposed together to form a core stack, the height of which is large relative to the strip width of each element. The core elements are electrically isolated from each other by insulating material (22) interposed between the elements at the region of juxtaposition.read more
