How do i calculate the power of an electric generator?

Question

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.

Answer 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.

Answer 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
