NEET Physics Lenz's Law MCQ Question
Type: MCQ-diagram based-Hard-Class 12
Consider a rectangular loop moving into a region with a uniform magnetic field directed normal to the plane of the loop away from the reader. According to Lenz's Law, which of the following correctly describes the direction of the induced current?
A
Clockwise, to oppose the increase in magnetic flux.
B
Counterclockwise, to oppose the increase in magnetic flux.
C
Clockwise, to align with the increasing magnetic flux.
D
Counterclockwise, to align with the increasing magnetic flux.
Correct Answer
Option A
Detailed Explanation
Lenz's Law states that the induced current will flow in a direction that opposes the change in magnetic flux. As the loop enters the magnetic field, the flux increases, and the induced current flows clockwise to oppose this increase.
