I'm developing a realistic sci-fi story in which power for the outer planets is produced from Jupiter's magnetic field. Now from Faraday's law I have V= N * A * (2*∏*RPM/60) B where N is the number of coils, A is the area of each coil, RPM is, well, RPM, and B is the field strength. I've calculated that the orbital period at a Joviostationary (yes it's a made-up word, but it works) orbit would be 600 minutes, giving me an "RPM" of .001667. Using 100 "coils" of 1 square kilometer each, and assuming 1.4 mT field at the poles, I get a paltry 24V. Is this correct, and how would I get the amperage in order to calculate power?
