Fig. 1 illustrates a cheaply manufactured, easily (programmable) controllable linear induction device for inducing motion into conducting devices, parts, etc. It consists of conventional printed circuit materials, such as fiberglass, copper or various other flexible and rigid plastics with copper. These are labeled as insulator and coils in Fig. 1. The coils are helical copper patterns etched or otherwise produced on the insulating plastic substrate material. The innermost connection to this helical coil is made by solder within a through-hole connecting to copper on the opposite side. The operation is as follows. A current is passed through a coil at time 0. Slightly afterwards (following a small time delay), current is passed through the adjacent coil.
