Hi,
I have a coil that is wound on a 1.125 inch diameter form and 3 inches
long space wound with 25 turns of 11 gauge aluminum wire...
I am trying to duplicate this coil only instead of using 11 gauge wire
I am using 12 gauge aluminum wire.
I was wondering if somebody could help me out and make sure my math is
right since I am unsure of how to go about making sure I match the
inductance.

I had this figured out once but mistakenly had the wrong wire
gauges...

Any help is greatly appreciated
Thank You
