In the figure, a wire loop has been bent so that it has three segments: segment bc (a quarter-circle), ac (a square corner), and ab (straight). Here are three choices for a magnetic field through the loop:
a) Rank the choices according to the work done per unit charge in setting up the induced current, greatest first.
b) Rank the choices according to the induced current, greatest first.
c) For each choice, what is the direction of the induced current in the figure? (clockwise or counterclockwise)
