Derive expression for the coefficient of mutual inductance between two long solenoids.

Explanation

Mutual induction : See Very Short Answer Type Question No. 17 (1 Mark) Coelficien! of mutual induction : See Short Answer Type Question No. 3 (3 Marks) SI unit of coefficient of mutual induction is Henry (H). One Heny: The coef+icient of mutual induction is said to be one henry if the rate of change of curent of one ampere per second through one coil induces an emfof one volt in the neighbouring coil.
