of the wings 117 and bounces or otherwise absorb off the rear sides 115 of the wings 117 at the same time magnetic lines of force are formed as the magnets 102 and 104 remain stationary in this aspect an electric current is produced when the coil 118 completes circuit to the scale 136 an embodiment of the present invention comprises coils 118 which are made of copper to produce electricity copper wire is a good conductor of electricity when in motion rotating around a magnet according to faraday 39 s law electricity is produced whenever magnetic lines of force between stationary magnets 102 104 cuts across the copper loop wire 118 which in motion which is part of a complete circuit the winding copper coils 118 in the embodiments are formed by winding a long copper wire in the shape of a spiral the copper coils 118 in fact act like a magnet when the current is turned on what happens is that the copper coil 118 possesses similar magnetic lines of force around it as an ordinary magnet does as mentioned above whenever magnetic lines cut across the winding copper coils 118 in a full circuit based on the revolutions per minute an electric current is generated within the axle or coil spring of the scale 136 or other receiving device referring now.
