NEET Physics Self & Mutual Induction MCQ Question
A diagram shows two concentric circular coils with radii r1 and r2, where r1 << r2, placed co-axially with centers coinciding. Which factor most directly affects the mutual inductance of this arrangement?
The relative permeability of the medium between the coils
The voltage applied to the coils
The material of the coil wire
The number of turns in the smaller coil
Correct Answer
Detailed Explanation
The mutual inductance depends on factors such as the relative permeability of the medium, as mentioned in the NCERT context. The other options do not directly affect the mutual inductance.
