Hello! today I have a question regarding the most efficient way to generate electricity by moving a magnet across a coil. The theoretical magnet would be moving in a circular motion fixed to the outer circumference of a driver wheel like in many simple generators, how does the physical torque and speed(rpm) of the flywheel affect the voltage and amperage of the outputting electricity? From what I can gather it seems the only important factors in generating current is the speed of fluctuations in the magnetic field (directly caused by the velocity of the wheel) and the number of windings in the coil. if torque power has no relation to magnetic fields theoretically could you not create a step-down gear ratio system making the output wheel spin much faster than the driving wheel at the cost of non-relevant torque which would increase the wattage/ efficiency overall? or am I missing something?? The only other outcomes I imagine is that torque somehow directly relates to outputting amperage so by improving the one you sacrifice the other making no difference in total power like a transformer? Or perhaps if the torque is too low and the rpm too high the resulting eddy currents generated will create enough friction to overcome the speedy but weak mechanical motion of the output wheel forcing it to halt. If anyone can give me a clean answer it would be much appreciated. I apologize if I was confusing or non-technical with my wording. Thank you for reading!
