NEET Physics Lenz's Law MCQ Question
Consider a circular loop oriented in a plane perpendicular to the page. A bar magnet is moved towards the loop with its North pole facing the loop, as depicted in Figure 6.1. According to Lenz's Law, what is the correct direction of the induced current in the loop?
Clockwise, to oppose the approaching magnetic field
Counterclockwise, to oppose the approaching magnetic field
Clockwise, to assist the approaching magnetic field
Counterclockwise, to assist the approaching magnetic field
Correct Answer
Detailed Explanation
Lenz's Law states that the induced current will flow in a direction that opposes the change in magnetic flux. As the North pole of the magnet approaches, the magnetic flux increases, causing a counterclockwise current in the loop to oppose this increase.
