Understanding Mutual Inductance
Mutual inductance is a phenomenon where a change in current in one coil induces an electromotive force (EMF) in another coil. Several factors influence mutual inductance, but one of them is independent of the others.
Factors Affecting Mutual Inductance
- Relative Separation: The distance between the coils significantly affects mutual inductance. As the coils are moved farther apart, the mutual inductance decreases.
- Relative Orientation of the Two Coils: The angle and alignment of the coils relative to each other can influence the magnetic coupling, hence affecting mutual inductance.
- Permeability of the Core Material: The type of material between the coils affects the magnetic field strength and, consequently, the mutual inductance. Higher permeability materials enhance mutual inductance.
Factor Not Affecting Mutual Inductance
- Reciprocity: This principle states that the mutual inductance between two coils is the same regardless of which coil is considered as the source or the induced coil. This means that if coil A induces a current in coil B, the same mutual inductance value applies when considering coil B inducing a current in coil A.
Conclusion
Thus, while relative separation, orientation, and core material permeability have direct effects on mutual inductance, reciprocity remains a fundamental property that does not depend on the physical arrangement or characteristics of the coils. This makes option 'C' the correct answer.

The mutual inductance of two coils is the property of their combination. It does not matter which one of them functions as the primary or the secondary coil. Hence, mutual inductance does not depend on reciprocity.
