ABSTRACT:
An electromagnetic induction apparatus having an even number of coaxially disposed flat coils each having a main winding conductor and tap winding conductors wound in parallel along at least a portion of the main winding conductor to form together a flat coil. The main winding conductors are connected together by connecting the inner end of the main winding conductor of each odd-numbered one of the even number of flat coils to the inner end of the main winding conductor of the adjacent even-numbered flat coil, and connecting the outer end of the main winding conductor of the even-numbered flat coil to the outer end of the main winding conductor of the succeeding odd-numbered flat coil. The tap winding conductors are connected together by connecting the inner end of each of the tap winding conductors of each odd-numbered one of the even number of flat coils to the inner end of the corresponding tap winding conductor of the adjacent even-numbered flat coil, and connecting the outer end of each of the tap winding conductors of the even-numbered flat coil to the outer end of the corresponding tap winding conductor of the succeeding even-numbered flat coil. Upright lead portions are formed on each of the outer ends of both the main winding conductors and the tap winding conductors of flat coils which are located at opposite ends of the even number of flat coils.
