Does anyone know how to make a mini generator run by mice going around in a wheel? Im hoping that the generator will be able to charge a battery. I'm in 7th grade, and this is for my science fair, so just an fyi: im not someone who usually does this stuff.Does anyone know how to make a mini generator run by mice going around in a wheel?If you get a little permanent magnet motor, it will work as a generator if you spin the shaft. You won't get much power out of it. It would take a long time to charge any battery. Especially using small animals like mice. Maybe you could just hook a meter to it to indicate electrical generation.
