(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A solenoid is wound with a single layer of copper wire of radius 0.38 cm. The solenoid is 4.5 cm in diameter and 3 m long. What is the inductance of the solenoid per unit length? Assume that adjacent wires touch each other and that insulation thickness is negligible.

radius of copper wire = 0.0038 m

length of solenoid = 3 m

diameter of solenoid = 0.045 m

2. Relevant equations

L = ([tex]\mu[/tex] * N^2 * A)/l

where L = inductance

[tex]\mu[/tex] = 4*PI*e-7 (perm. of free space)

N = number of turns

A = cross sectional area

l = length of the solenoid

3. The attempt at a solution

by working backwards, i figured the number of turns = 3/2*[tex]\Pi[/tex]*0.0038, but its not working out any help?
