A solenoid has length 1, area A and number of turns N. If it is filled with material of permeability p then its self inductance is:
A. L = \(\frac{l N^{2} A}{\mu}\)
B. L = \(\frac{\mu \mathrm{N}^{2} \mathrm{~A}}{l}\)
C. L = \(\frac{\mu \mathrm{NA}^{2}}{l}\)
D. L = \(\frac{\mu l^{2} \mathrm{~A}}{\mathrm{~N}}\)
