Hi. In class we are currently studying electromagnetism. The unit we are currently doing is on generators and motors using faradays law of induced emf. While reading, i had a random thought: If a generator is set up, such that its output current is directed to a motor, which creates rotation, which in turn is used to turn the generator coil, will the system continue to operate forever, assuming resistance free wires. Ofcourse, the generator will have to be given an initial 'push' to get the current flowing. Now, im sure there must be some flaw in what ive said, or some physical problem with the setup, since as far as i am aware, perpetual motion is impossible. Ive just posted this really for the sake of curiosity, so if anybody is able to comment on what ive said, id be greatly appreciative :) Thanks, Dan.
