Mutual inductance is defined as the current induced in a coil in proximity when the flux change is produced by the same coil.
Given: -
Two long co-axial solenoids each of length l. The radius of the inner solenoid S1 by r1 and the number of turns per unit length by n1. The corresponding quantities for the outer solenoid S2 are r2 and n2, respectively. Let N1and N2 be the total number of turns of coils S2 and S2, respectively.
