How to design a coil for a specific inductance that you need, including how to calculate the inductance and where to find an online inductance calculator. This goes through all the parameters: number of turns, area, length and relative permeability as well as mentioning some other factors like capacitance, frequency and coupling.

The webpage with the inductance calculator is here:
