Imagine that we constrain a rectangular loop to move through a square region where the magnetic field 
is uniform and downward (in the -z direction), as shown below. Assume that 
outside that region. We can divide the loop’s motion up into five phases: For each of the five phases, which of the following is true? The loop has not yet entered the magnetic field.
A. Current flows clockwise in the loop.
B. Current flows counterclockwise in the loop.
C. Current does not flow in the loop.
C. Current does not flow in the loop.
