Which of the following is referred to as mutual inductance?
A) Two unconnected inductors have their coils wound in the same pattern.
B) Two solenoids have the same inductance.
C) The changing flux from one inductor produces an emf in another inductor.
D) The numerical value of one inductance is the reciprocal of another inductance in the same circuit.

Mutual inductance refers to the phenomenon where the changing magnetic field from one inductor induces an electromotive force (emf) in another nearby inductor. This can be used in applications such as transformers and inductive coupling. Option A refers to inductors having the same winding pattern, but this may or may not result in mutual inductance. Option B refers to inductors having the same inductance, but this does not necessarily result in mutual inductance. Option D refers to inductances being inversely proportional, but this does not suggest mutual inductance.
