SUMMARY

The discussion centers on the application of Faraday's Law of Electromagnetic Induction in the context of building a mini electric generator. The formula V=-N*(ΔBA)/(Δt) is used to calculate the generated voltage, where N represents the number of turns of the coil. The user inquires whether wrapping a copper coil 200 times around a single ring would produce more voltage than wrapping it around four smaller rings, each with a diameter of 1/4 that of the single ring, in a figure-eight motion. The total area of the four smaller rings is less than that of the single larger ring, impacting the magnetic flux and thus the voltage generated.

Hey guys. I'm building a mini electric generator and I would like some clarification on Faraday's Law.

So his law states that:

V=-N*(ΔBA)/(Δt)
Where voltage generated equals the number of turns times the negative rate of magnetic flux.

So my question regards the number of turns part. So my hypothetical situations involve one with a single ring and another with four rings of 1/4 the diameter of the one ring. If I wrapped copper coil around the one ring 200 times would the voltage generated be greater than if I wrapped the copper wire around the four rings 200 times? Wrapping the wire around the four rings would be in a figure eight kind of motion.

Thanks for your input! Sorry I didn't have a picture, I couldn't find one or couldn't figure out a good way to illustrate it.

How does the total area of the four rings compare to the area of the single ring?
