how to make a 10mH choke coil at home !!!!!!!!!!

Use magnet wire and possibly a core. Depends on the specification.

Try to use this calculator:

:D

First decide what current is supposed to pass through it and then select an enamelled copper wire for the same. Then start winding on a core and measure with a L meter at regular intervals. Example : May be if you stop at 20 turns and you get 1Mh, it means by 200 turns, you'll recah 10Mh.
