Write an expression for mutual inductance of two co-axial solenoids.

Define the term 'mutual inductance' between the two coils. Obtain the expression for mutual inductance of a pair of long coaxial solenoids each of I and radii r_(1) and r_(2)(r_(2)gt gt r_(1)) . Total number of solenoids are N_(1) and N_(2) respectively.
