It is not a toroidal coil, the wire is wrapped on like fishing line is wrapped on. If I am interpreting you correctly, the magnets do slide around like you describe. They rotate on a pivot that is perpendicular to the plane of the "circle:" the wire is wrapped on.

1" diameter 1/4" thick N52 grade neodymium magnets, with a surface field of 3309 Gauss. They are both attached 1.68" from the very center of the coil. How would I go about deriving such a formula?

What other information is needed? Edit: I know of the formula ε=NABω sin ωt , but I do not know what unit B is, other than that it is the B field. This equation doesn't seem to make sense in the context of a stationary coil, however. I also know the formula ε=-N(ΔΦB/Δt) , where Φ≡BA cos θ...

A 4.5" tube that's 1/2" thick, with 1,000 wraps of 30 gauge magnet wire around that. Two neodymium disk magnets spin inside of the tube (magnetized on the face, less than 2/5" from the center of the magnet to the inside of the tube.

I'm making an AC generator with a stationary coil and rotating magnets. What would be the correct formula to find induced voltage at a certain rotation speed (along with the units)? All sources I've found are either non-applicable or do not explain what units to use. Thank you for the help.
