Two coils are placed close to each other. The mutual inductance of the pair of coils depends upon:

  1. A
    the rates at which current are changing in the two coils
  2. B
    relative position and orientation of the two coils
  3. C
    the materials of the wires of the coils
  4. D
    the currents in the two coils

Solution & Step-by-step Explanation

Mutual inductance is a geometric property. It depends on the number of turns, area, separation, and relative orientation of the coils, as well as the permeability of the core material. It does not depend on the current or its rate of change.
