2) (challenge) In the picture to the right, the loop A has the following currents running through it as a function of time: A B t = 0 s: No current t = 1 s: A little current, clockwise viewed from the right t = 2 s: Lots of current, clockwise viewed from the right t = 3 s: A little current, clockwise viewed from the right t = 4 s: No current Specify the currents as viewed from the right: a) Does the magnetic flux through loop B change between t = 0 s and t = 1 s? What about between t = 1 s and t = 2 s, t = 2 s and t = 3 s, or t = 3 s and t = 4 s? In what direction is each of these changes, if any? b) Based on a), is there a current in loop B between t = 0 s and t = 1 s, t = 1 s and t = 2 s, t = 2 s and t = 3 s, or t = 3 s and t = 4 s? In what direction does the current flow in each case? c) Graph the current in loop A and the current in loop B as a function of time on the same graph. How are the two curves ( IA and IB ) related? Define positive current as clockwise and negative as counterclockwise (as viewed from the right). d) Do your graphs agree with the mathematical description of Lenz' Law
