From what I understand about generators, is that the higher the electrical load that is placed on the gen, the more power is required to maintain the rpm. This is because the magnets in the rotor will create a voltage in the coils, which in turn produce an opposing magnetic field which slows down the rotor. So what would happen if you wound the coils in the other direction? Would the electrons still flow in the same direction? Is the generated opposing magnetic field dependent upon the polarity of the passing permanent magnet on the rotor or the direction that the coils were wound in?
 
So what would happen if you wound the coils in the other direction?
The polarity of the generated voltage and opposing field would be reversed, so you'd be no better off.
 
Njguy, have you seen this site? A lot of information there. **broken link removed**

the magnetic field generated is dependent on BOTH the polarity of the magnet, the direction the coil is wound AND also the direction the coil is passed underneath. The coil passing through the magnetic field generates a current. This current, flowing, produces another magnetic filed that ALWAYS opposes the generating field, just by the nature of the way it is generated. Therefore, it doesn't matter which way you wind the coils, you will get an opposing field generated. If you reverse the coil, you get the opposite current flow and thus the opposing field. If you change the magnet polarity, you get the opposite current flow and thus an opposing field. If you change the direction of travel through the field, etc...

This is basically the same principle inductors work on, and why they resist a changing current... and it doesn't matter the polarity of that change, or the step direction of the voltage.
