I have the length of the first coil, the number of turns in both, the current through the first coil and the cross-sectional area of the coil inside. I want to find the induced voltage. I know I should use Faraday's law, but I'm not sure exactly how. I think I've over-thought it and confused myself!
I tried finding the magnetic field of both then summing them together, but this doesn't really help. I've considered flux, but I can't see how I would use this to get an answer. I just don't quite understand how the coils interact with each other in this orientation.
