Assembly Instructions

Instructions
Two flat wound coils are hung from a hinged support parallel to each other, and are connected to AC or DC through a reversing switch. Set the HVDC at nearly full; set the reversing switch in one position and then close the series switch momentarily, and the coils will attract or repel. Changing the position of the reversing switch will cause the coils to reverse their directions. Open the series switch. The low voltage AC or DC supply works well at about 15 amperes.
