Abstract
Abstract This coil comprises an annular core surrounded by a plurality of layers of electrically conductive wire windings separated from each other by at least one layer of metal foil, and at least one layer of elastic dielectric material. By selective connection of the wire windings and the intervening foil layers in electric circuits, the coil may be made to function selectively as a choke, filter, signal delay, or as a storage device or absorber for impulse energy. By adding axially extending metal strips to the coil between its layers of windings, the coil is suitable for use in an electric current generator of the magnetomotive variety.
