Two coaxial solenoids are made by winding thin insulated wire over a pipe of cross sectional area A = 10 cm2 and length = 20 cm. If one of the solenoids has 300 turns and the other 400 turns, their mutual inductance is \(\left[\mu_{M}=4 \pi \times 10^{-7} \mathrm{Tm} \mathrm{~mA}^{-1}\right]\)
- 2.4\(\pi\) x 10-5 H
- 4.8\(\pi\) x 10-4 H
- 4.8\(\pi\) x 10-5 H
- 2.4\(\pi\) x 10-4 H
Answer
(D) 2.4 x 10 -4 H
