To manufacture a solenoid of length ' $l$ ' and inductance ' $L$ ', the length of the thin wire required is (Diameter of the solenoid is very less than length, $\mu_0=$ permeability of free space)

$\left[\frac{4 \pi l L}{\mu_0}\right]^{\frac{1}{2}}$

$\left[\frac{2 \pi l}{\mu_0 \mathrm{~L}}\right]^{\frac{1}{2}}$

$\left[\frac{4 \pi \mu_0}{l \mathrm{~L}}\right]^{\frac{1}{2}}$

$\left[\frac{2 \pi \mu_0 \mathrm{~L}}{l}\right]^{\frac{1}{2}}$
