Question

3. A very long wire is along the z -­‐ axis and carries current I in the positive z direction. A wire segment of length L is parallel to the long wire and is initially a distance x 0 away from it along the positive x -­‐ axis. The midpoint of the wire segment is on the x -­‐ axis. At time t = 0, t he wire segment begins moving away from the long wire with constant velocity € v = v 0 ˆ i in the positive x direction. The wire segment remains parallel to the long wire as it moves. Find the magnitude of the induced voltage difference between the top and bottom of the wire segment as a function of time. Also determine which end, top or bottom is at the higher voltage.
