Hello i am new to coil,
and i will like to make desired coil inductance if its possible

can somebody help me
thanks

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.

but i dont know, let say inductance of 1mH, how do i have to do?

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.
