Question

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

  1. The rates at which currents are changing in the two coils   
  2. Relative position and orientation of the two coils   
  3. The materials of the wires of the coils   
  4. The currents in the two coils   

The correct answer is: The materials of the wires of the coils


    Mutual inductance of the pair of coils depends on distance between two coils and geometry of two coils.

    There are two solenoids of same length and inductance L but their diameters differ to the extent that one can just fit into the other. They are connected in three different ways in series. (1) They are connected in series but separated by large distance, (2) they are connected in series with one inside the other and senses of the turns coinciding, (3) both are connected in series with one inside the other with senses of the turns opposite as depicted in figures 1, 2 and 3 respectively. The total inductance of the solenoids in each of the case 1, 2 and 3 are respectively
