NEET Physics Self & Mutual Induction Assertion Reason Question
Assertion (A): The self-induced emf in a coil opposes the change in current flowing through it.
Reason (R): The self-inductance of a coil is dependent on its geometry and the permeability of the medium.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The self-induced emf opposes changes in current due to Lenz's law (back emf). The self-inductance depends on geometry and permeability, but this does not explain why emf opposes the change.
