Conductive devices called electric coils serve as key connections and transmitters within a myriad of circuits. In the most basic construction, a metal wire is wound around a core insulator, and the two ends are made into electrical connection terminals called “taps.” Without these devices, electrical current would not be able to be controlled, directed or transformed in electronics, automotive, medical, computer, appliance, telecommunications and industrial manufacturing applications. To start a car there is needed the spark that induction coils,...
