NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Hard-Class 12
Consider a long solenoid S1 with a secondary solenoid S2 placed inside it, both having a large number of turns. Which parameter does NOT affect the mutual inductance between S1 and S2?
A
Length of solenoid S1
B
Number of turns in solenoid S1
C
Radius of solenoid S1
D
Current in solenoid S1
Correct Answer
Option D
Detailed Explanation
Mutual inductance M12 between two solenoids depends on the number of turns, the length, and the radius of solenoid S1 as shown in equation M12 = μ0 n1 n2 π r²1 l. The current in solenoid S1 does not affect the mutual inductance.
