Magnetic Field Solenoid Calculator
The magnetic field generated by the coil is given by its inductance (geometry of the coil) and flowing current. For the solenoid coil, the inductance is given by:
$$ L = μ{\frac{N^{2}S}{l}} $$
where µ is the permeability of the environment inside of the coil (could be air or yoke to increase the magnetic field generated by the coil), N is the number of windings, S is the cross-section area of the coil and l is its length.

Then magnetic field generated by the current I flowing through the coil is:
\[ B = {\frac{L.I}{NS}} \]
