A) the rates at which currents are changing in the two coils
B) relative position and orientation of the two coils
C) time for which current is flown
D) the currents in the two coils
Correct Answer: B
Solution :
[b] Mutual inductance of the pair of coils depends on distance between two coils and geometry of two coils. \[(\because M={{\mu }_{0}}{{n}_{1}}{{n}_{2}}\pi r_{1}^{2}l)\]
