Question by bellinda jessica c: How does a magnetic motor just keep producing energy?
I’m doing a research paper on motors which use magnets (like the one shown here http://www.magniwork.com/?hop=gbancrig) now, my question is how the motor just keeps producing energy. i mean, isn’t it supposed to be that energy can’t be created or destroyed?

Magnets do eventually lose power as they use it up. So called permanent magnets will last about 400-450 years depending on how fast they expend their magnetism maybe even less. Nothing is created or destroyed, it is just used up very slowly compared to other forms of fuel, in this case the fuel being the magnets themselves.
