Cartoon joke diagram of a wind turbine with a rotor of grey blades on a central hub with a trolling face, driven by red horseshoe magnets; the caption reads Wind turbines do not need wind to function if you use magnets.


Why aren't we using this method?
 
Because of Newtons third law. The magnets pull on the turbine blades, but in turn they themselves are pulled towards the turbine blades resulting in zero motion.
