The Mutual inductance $M_{12}$ of coil 1 with respect to coil 2- |
Decreases as they are brought nearer. Depends on the current passing through the coils. Increases when one of them is rotated about an axis. is same as $M_{21}$ of coil 2 with respect to coil 1. |
is same as $M_{21}$ of coil 2 with respect to coil 1. |
The correct answer is Option (4) - is same as $M_{21}$ of coil 2 with respect to coil 1. $M_{12}=M_{21}=μ_0n_1n_2\pi r^2$ ∴ Mutual inductance is same in the both coil. |
