In one of NASA’s space tether experiments, a 20.0 km-long conducting wire was deployed by the space shuttle as it orbited at 7.86 x 103 m/s around Earth and across Earth’s magnetic field lines. The resulting motional emf was used as a power source. If the component of Earth’s magnetic field perpendicular to the tether was 1.65 x 10T, determine the maximum possible potential difference (in V) between the two ends of the tether. HINT
