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.
