Abstract
A bi level electrical inductance coil wherein flat, thin conductors are formed and supported on both sides of a flexible dielectric substrate such that the center line of the conductors on one side overlays the space between the conductors on the other side and such that both ends of each conductor are formed so as to be interdigitated; the ends on one side of the substrate interdigitated with the ends on the other side of the substrate; the substrate and conductors bent so that the conductor ends contact adjacent conductor ends to form continuous turns thus forming a relatively thin flat coil with overlapping conductors to provide a uniform magnetic field particularly useful in bubble memories.
