a) Give a counterexample to show that the following statement is false: "When the magnetic field through a loop changes, currents run in the loop in such a way as to make a new magnetic field in the opposite direction to the original one."

(b) Two metal rings lie side by side on a table. Current in the left ring runs clockwise and is increasing with time. This induces a current to run in the right ring. Does this induced current run clockwise or counterclockwise? Explain, using a diagram.
