Magnetism & Electricity (2 magnets - Field)

declanka

I am trying to calculate the output voltage for 1 coil in an axial generator/altenator

I have 2 magnets with Br Max 13200 Gauss on opposing sides of the rotor (N-S facing), The coil is between them on stator. Using faradays equations what is the effective Br (Gauss/Tesla) that should be used.

Thanks

... should be used to achieve what aim?

Oh you mean, what approximate value should you use for B in Faraday's Law?
That will depend on the exact geometry of your setup - which determines the field characteristics - and the tolerances you want to work with (which determines how much hand-waving you get to use.)

You could, I guess, use a pole model for the magnets to predict the actual field through the loop at each angle?
