Mutual inductance of two coils can be increased by

Mutual inductance of two coils can be increased by

Options

  1. Adecreasing the number of turns in the coils
  2. Bincreasing the number of turns in the coils
  3. Cwinding the coils on wooden cores
  4. DNone of these

Correct answer

B. increasing the number of turns in the coils

Step-by-step solution

Mutual inductance of coils, M=μ0μrN1N2Al.\frac{\mu_0 \mu_r N_1 N_2 A}{l} .It is clear that mutual inductance of coils can be increased by increasing the number of turns in the coils.
