NEET Physics Lenz's Law MCQ Question
A circular loop is moving into a region of a uniform magnetic field of 0.5 T directed into the page, increasing the magnetic flux through the loop. If the loop induces a current of 2 A in order to oppose this change, what is the direction of the induced current as observed from above?
Clockwise
Counterclockwise
Towards the observer
Away from the observer
Correct Answer
Detailed Explanation
According to Lenz's law, the induced current will oppose the increase in magnetic flux by creating its own magnetic field out of the page, which requires a counterclockwise current.
