Imagine a satellite (Pioneer 10) in an orbit around Ganymede (Jupiter's moon). You want to generate electricity by attaching a conducting cable 10km long. If the speed of the satellite is 7 km/s and the magnetic field of Ganymede is 60 nT how much emf will be generated? (Hint1: assume that magnetic field is perpendicular to the plane which contains the cable. Hint2: you can think of it as motional emf) Is it possible to produce electricity this way forever? Explain your answer.
