Portable Generator For Sale

How do i calculate the power of an electric generator?

I am trying to find a formula to calculate the power of an electric generator, based on are of coils, dimeter of wire (if it matters), rotational speed and so on. I am building one to hook up to a bike and i would like to be able to have a formula to predict voltage given all the parameters.

1. my goodness... I once was in school and had to learn this it where lessons of 4 hours a week and then for half a year I can tell you its alot alot of parameters 50 ~ 100 forget it.
2. The maximum EMF of a coil spinning in a magnetic field is Emax = NBAω where N = # of coils, B = field strength, A = area of coil and ω = rotational velocity. Good luck
