8. There is a square loop of wire with side length L moving to the right at a speed of v. The resistance in the wire is R. To the right of it is a region with a magnetic field with field strength B into the page. Find the current in the wire loop (a) before the loop reaches the magnetic field, (b) while the loop is entering the field, (c) while the loop is entirely within the field, (d) while the loop is exiting the field, and (e) after the loop leaves the field. Be sure to include the direction of the curret (i. e. clockwise or counter-clockwise). All your answers will be in terms of L, v, B, and R.
