摘要： A magnetic device having height includes a magnetic core, a first foil winding, and a second foil winding. The magnetic core includes first and second inner posts separated from each other in the height direction by a first inner gap and first and second outer elements separated from each other in the height direction by a first outer gap. The first foil winding is wound around the first inner post without extending along a height of the first inner gap and without extending along a height of the first outer gap. The second foil winding is wound around the second inner post without extending along the height of the first inner gap and without extending along the height of the first outer gap.

摘要： A coating (626) comprising a ferroelectric, lossy dielectric, ferromagnetic or semiconductor material is disposed near an object (620). AC current flows through an electrical conductor (624), creating an electromagnetic field. The coating (626) absorbs energy from the electromagnetic field, thereby generating heat, which melts snow and ice on the object (620).
