New ac wind gen has no output. Coil has become slightly magnatized. Is this my problem or have I missed something else?

did u make the ac generator or buy it I think there is no change in magnetic flux done by the coil your voltage depends on the number of turns and change in flux according to faraday
E = N (change in flux / change in time)
so if the coil rotation is greater it means that rate of change in flux is greater so more is the voltage and in your case I think the wind is not enough to rotate the coil. Please give the feecback to my e mail [email protected] if this helps u thanku.

This is new... if it was a purchaced item didn't it come with any form of warranty?

Is it running at rated speed,check the AVR.
