40. The north pole of a magnet is moved toward a copper loop, as shown in figure below. If you are looking at the loop from above the loop, what will you say about the induced current? The induced current in the loop is circulating clockwise due to Lenz's law. The induced current in the loop alters from clockwise to counter-clockwise due to Lenz's law. O The induced current in the loop is circulating counter-clockwise due to Lenz's law. O There is no current in the loop because there is no battery or any other source of voltage.
