NEET Physics Self & Mutual Induction Assertion Reason Question
Assertion (A): The mutual inductance of two coaxial solenoids depends on the medium between them. | Reason (R): The mutual inductance is proportional to the relative permeability of the medium between the solenoids.
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 mutual inductance M of two solenoids depends on the medium between them, as it is given by M = μ_r μ_0 n_1 n_2 π r_1^2 / l, where μ_r is the relative permeability of the medium.
