Inductance of solenoid
$$L = \mu\cdot \mu0\cdot n^{2}\cdot S\cdot l$$
L - inductance
μ - relative magnetic permeability
μ0 - magnetic constant
n - number of turns in a winding per length unit
S - cross-sectional area
l - length of solenoid
μ - relative magnetic permeability
μ0 - magnetic constant
n - number of turns in a winding per length unit
S - cross-sectional area
l - length of solenoid
