Hey everyone, I'm new to the forums, this my first post.

 

I'm working on building an electric power generator using rotating magnets. I'm trying to work every thing out on paper before I start building, but I'm struggling with the equations. Say I have a three magnets of arbitray strength rotating within a solenoid with arbitrary length and amount of coils. What equations specifically would I use to calculate the amount of electricity this system could produce? I assume the speed at which the magnets are rotating matters, as well as what material the wire in the solenoid is made of, say I'll use copper.

 

I know this has something to do with Faraday's Law, and magnetic field strength, but I can't seem to boil down the equations to something simple enough to work with. Any advice or referrals to informational websites would be greatly appreciated!

IIRC, Faraday's Law can be written as:

[math]V={\Phi}N[/math] Where V is voltage, [math]\Phi[/math] is magnetic flux, and N is the rotational speed.
