Two coils A and B placed in a circuit. When current in the coil A changes by 0.8 A the magnetic flux in coil B changes by 0.16 Wb. The mutual inductance between the coils is

Answer: (D)

Solution

The flux linked with coil B due to current in coil A is , so for changes . Therefore \dfrac{Δφ_B}{Δ I_A}$ =
