I am new to StackExchange and trying my best to stay within the rules. I have invented an efficient mechanism -- a rotating mass magnetically attached inside a closed loop (GB 2517244). I am attempting to apply an EMF (electro-magneto force) system into the mechanism to make an 'at source' electricity generator. The mechanism is based on the Kinetic (Chinese) Wheel yoyo. I am using a 1.5kg flywheel assembly rolling 0.5 m down a 3 degree slope. The mechanism, using a battery, sensors and electromagnets to rock a counter-balanced beam (as the engine), is made to complete an 'orbit' at 1 metre per second @ approximately 1600RPM.
Leaving aside 'start up' considerations and given each GPE (gravitational potential energy) renewal costs two 0.33amps inputs from the electromagnets, can I achieve more electrical output from an EMF arrangement along the transits than is needed to rock the mechanism?
