A bar of length 1.5 meters moves to the left at 4.6 m/s along a set of conducting rails. The rails and bar have a net resistance of 10 Ohms. A magnetic field of 2 Tesla points out of the page.
a.) In which direction does the current flow in this circuit?
b.) Determine the induced electromotive force.
c.) Find the current.
d.) How hard do you have to push to maintain the speed of 4.6m/s?
