# Thread: Building a Windmill Electromagnetic Generator

1. Hi guys, I tried making a windmill electromagnetic generator and even used the electromagnetic called "Ultra-simple Electric Generator" made by William Beaty but it didn't work. I believe his site is http://www.eskimo.com/~billb/amateur/coilgen.html

Since this generator had failed me, I was hoping if anyone know any other ones that I can make or if you know how to make one. I have been having trouble making one for my physics project. Can someone possibly indicate some sources or sites that you may know of telling you how to design one? I looked over many websites and still couldn't find a generator.

Basically the generator I want to make is a windmill that generates electricity to a light bulb... I may need help designing one and if you can, please help me out.

3. I don't know what exactly isn't working for you. I would suggest checking the arrangements of the magnets. I believe you need all of the poles facing one way in order to get an AC Current. This might be wrong so then try halfing 2 souths with 2 norths, although it seems to me that would be DC current.

Let me know if that isn't it. I would bet that your voltage or current aren't strong enough. Whats the rating on the bulb if its only given in watts the equation is

P=IV=(V^2)/R or (I^2)R

Rearrange accordingly.

5. then hopefully someone else here has a suggestion.

too difficult, need something simple

8. I can see how, with a wire connected to a greased probe, one can regulate the voltage to a continuous and useful amount.

9. Since this generator had failed me
How did it fail?
