A circular coil lies flat on a horizontal surface. A bar magnet is held fixed above the center of the coil with its north pole pointing downward. What is the direction of the induced current in the coil

Explanation:

If the magnet is dropped from this position, then the direction of the induced current in the coil would be anticlockwise. Lenz's law allows us to predict the direction of the induced current in a circuit. It is also known as the Right hand rule. It states that the current that is being induced in a particular circuit is as a result of the change in the magnetic field in order to oppose the change in the magnetic flux and also to apply an mechanical force that is opposing the motion. Because of this, the current is pointed to the direction of  the pole, to oppose this the induced current should be directed anticlockwise.
