    Welcome to EP.
    Here you have a guide and calculator (there are many others on the web).
    You can also buy ready made standard coils.

    An example:

    iron core, μ=100
    diameter 1 cm
    length 10 cm
    No of trurns=100

    You get 0.99mH (put the values in the calc. and check).
    Note:
    1. the wire is 10/100=1mm thick.
    2. you can play with the diameter,length and turns to get the same results in other sizes.
