I decreasing In the figure above, a loop is located near a long wire with current flowing as indicated. 8The original B field penetrating the loop points the page. O If the current in the wire decreases, then the magnetic flux o in the loop 0Therefore, the loop generates an induced B field that points the page. e This induced B field is due to an induced current that flows in the loop.
