According to Faraday's law of electromagnetic induction, a changing magnetic field induces an electric current in a nearby conductor. The direction of the induced current can be determined by Lenz's law, which states that the current will flow in a direction that opposes the change in magnetic flux that produced it. In this case, the decreasing magnetic field in the coil will produce an induced current in the opposite direction to try to maintain the original magnetic flux. Therefore, the induced current will flow counterclockwise as viewed from the top.

The Magnetic Field in the Coil Is Upward and Decreasing
