Assertion: When two coils are wound on each other, the mutual induction between the coils is maximum. Reason: Mutual induction does not depend on the orientation of the coils.

1. If both assertion and reason are true and the reason is the correct explanation of the assertion.
2. If both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. If assertion is true but reason is false.
4. If the assertion and reason both are false.

Correct answer: If assertion is true but reason is false.

Solution

When two coils are wound on each other, the flux linkage is maximum, so mutual inductance is maximum. However, mutual induction does depend on the orientation of the coils, so the reason is false.
