Homework Statement
Calculate the self inductance of a solenoid that is tightly wound with a wire of diameter .1 cm , has a cross sectional area of .9 cm2 and is 40 cm long?
Homework Equations
The Attempt at a Solution
the formula L=u0n2V where V=volume and n=number of turns per unit length is valid when we assume the wire of solenoid is very thin. Now if the wire is so thick that it is not negligible hen how to find the self inductance?
