The mutual inductance of a pair of solenoid depends :
(A) on their separation
(B) on their relative orientation
(C) on the current flowing
(D) on the number of turns in the solenoids
Choose the correct answer from the options given below :
Answer & explanation
Correct answer: option 4
Mutual inductance between two coils depends on permeability of core, the number of their turns and cross sectional area of the common core. Mutual inductance of the coils also depends on their separation as well as their relative orientation
