An astronaut is connected to her spacecraft by a 25-m-long conducting wire tether cord as she and the spacecraft orbit earth in a circular path at a speed of 3.0 x 103 m/s. At one instant the voltage measured between the ends of the wire embedded in the cord is measured to be 0.50V. Assume (worst-case) that the tether cord is perpendicular to the vertical component of Earth’s magnetic field at that location which is the peak ∆V measurement. (a) What is the magnitude of the Earth’s B-field at that instant? (b) Does the measured voltage change as the system moves from one location to another, and why? (c) What could you do to mitigate the problem?
