I've got a question that's been bugging me for a while. Is there a "best" way to position a magnet and wire coil inside a generator? I saw a "how-to" on how to build a wind power plant and they had the windings laying down on a flat plane, positioned around a center point. From the center point of the plane a shaft poked out perpendicular to it and some arms reached out off the shaft that had magnets that passed really close to each coil. An alternative way would be to attach the magnets directly to the shaft and wrap the coil around the magnet+shaft combo.
Would one way be better than the other?
