NEET Physics (general) MCQ Question

Type: MCQ-conceptual-Hard-Class 12

Which of the following statements about mutual inductance and electromagnetic induction is correct?

A

Mutual inductance between two solenoids depends on the product of the number of turns in each solenoid.

B

The induced emf in a coil is independent of the rate of change of magnetic flux through it.

C

Mutual inductance can only occur between coils that are in direct contact with each other.

D

The magnetic field inside a solenoid is uniform only when the solenoid is short and has fewer turns.

Correct Answer

Option A

Detailed Explanation

According to the mutual inductance formula, M12 = μ0 n1 n2 πr^2 l, the mutual inductance is indeed dependent on the number of turns in both solenoids. Other options reflect misconceptions about electromagnetic induction.
