Question

Define mutual inductance between two long coaxial solenoids. Find out the expression for the mutual inductance of inner solenoid of length l having the radius r1 and the number of turns n1 per unit length due to the second outer solenoid of same length andber of turns per unit length.

Answer 1

efine mutual inductance between two long coaxial solenoids. Find out theexpression for the mutual inductance of inner solenoid of ... per unit length due to the second outer solenoid of same length and n2 ... Two concentric circular coils C1 and C2, radius r1 and r2 (r1<<r2) respectively are kept coaxially.
