Abstract: The disclosure relates to a coil and an electrical system including the same.

Abstract: The present disclosure relates to a coil assembly. According to a first embodiment of the present disclosure, there is provided a coil assembly including a coil including a multilayer film which is extended between a first longitudinal end and a second longitudinal end of the multilayer film, which are opposite to each other, and which is wound to form a plurality of loops which are substantially concentric, wherein the multilayer film includes: cut edges which are extended between the first longitudinal end and the second longitudinal end, and are opposite to each other and are substantially parallel to each other; a metal layer; and a magnetic layer disposed on the metal layer, wherein, at one or more of the first longitudinal end and the second longitudinal end of the multilayer film, the metal layer is electrically connected to a conductive terminal.

Abstract: The disclosure relates to a coil, a planar coil, and a method for making a coil. Specifically, according to an embodiment of the disclosure, a coil includes: main coil surfaces which are opposite each other and are substantially planar; and a multilayer film which is wound to form a plurality of loops which are substantially concentric, and the plurality of loops include an innermost loop including a first longitudinal direction end of the coil, and an outermost loop including a second longitudinal direction end of the coil, and the multilayer film includes a plurality of first electro-conductive layers which alternate with each other, and one or more second electrical insulation layer.
