The inductance of an air core solenoid is given by:
\(L={\mu _oN^2A\over l}\)
where, L = Inductance
N = No. of turns
A = Area
l = Length
Calculation
Given, N = 200 turns
A = \(\rm \left(\frac{2}{\pi}\right)m^2\)
l = 400 cm = 4 m
\(L={4\pi\times 10^{-7}\times (200)^2\times {2\over \pi}\over 4}\)
L = 8 mH
