A simple circuit simulator for electric AND magnetic flow. Assemble sources, wires, bulbs, manual switches, electromagnetic solenoid switches and coils into complete circuits. This is THE AgentSheets classic going back to 1990. Electric World was first implemented in Lisp and then in graphical rewrite rules. The Visual AgenTalk generated version restores most of the capabilities of the original. Use the hand tool to operate switches. See what happens then you close the switch below the left coil (feedback). More Information
