Physics-Lenz's Law
NEET Physics Lenz's Law Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): When the North-pole of a bar magnet is pushed towards a coil, the induced current flows in a direction that opposes the motion of the magnet. | Reason (R): According to Lenz's law, the induced emf generates a current that opposes the change in magnetic flux that caused it.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false but R is true.
Correct Answer
Option A
Detailed Explanation
Lenz's law states that the induced emf produces a current that opposes the change in magnetic flux, explaining why the induced current opposes the motion of the magnet.
