How to make a generator more efficient?

Question

I was wondering... you know how generators usually have a bunch of copper wire basically wrapped around over and over the area where the magnet will be rotating....

I was wondering if you got a larger ammount of copper if it would produce more power? like for example if instead of a bunch of wire wound up it will be basically a copper donut with a rotating magnet in the middle to produce power....

Would the coper donut produce more power than a bunch of coper wire wrapped into a donut shape?

Answer 1

no

Read up on generator and motor design, you will see that your idea will not work.

Answer 2

More conductors cutting the same number of magnetic lines of force OR the same number of conductors cutting a greater number of magnetic lines of force would increase output.

The shape of the copper coils also affects output.

To increase efficiency, reduce friction in the generator.
