Physics-Self & Mutual Induction

NEET Physics Self & Mutual Induction Assertion Reason Question

Type: Assertion Reason-assertion-Easy-Class 12

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.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false but R is true.

Correct Answer

Option A

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.
