Faraday’s law states that the magnitude of the induced emf in a circuit is equal to the time rate of change of magnetic flux through the circuit. Lenz’s law states that the polarity of induced emf is such that it tends to produce a current which opposes the change in magnetic flux that produced in it.Since the rod is moving to the right, more magnetic field lines will be coming out of the loop and induces a current in the clockwise direction in the loop. So, the direction of the induced current on the bar is down. Therefore, option (b) is the correct answer.
