Two long coaxial solenoids of the same length L, have inner and outer coils with diameters $D_1$ and $D_2$ and number of turns $N_1$ and $N_2$, respectively. What will be the ratio of the self-inductance of the inner solenoid to the mutual inductance of both the solenoids? |
$N_1\,{N_2}^{-1}$ $N_2\,{N_1}^{-1}$ $(N_2\,{D_2}^2)/(N_1\,{D_1}^2)$ $(N_2\, D_2)/(N_1\, D_1)$ |
$N_1\,{N_2}^{-1}$ |
The correct answer is Option (1) → $N_1\,{N_2}^{-1}$ |
