[Lowfer] 8 ft Square Loop

[Michael Silvers]

Hi Lewis & Group,

It probably an Iron Core -26 Material 75�o
Yellow/White in color, typical inductor material for
power supplies.  See
http://www.micrometals.com/materials_index.html for
more data, like Al values, etc.

I suggest picking up a ferrite core -43, -77, -F, or
-J(75) material. �o of 850, 2000, 3000, 5000,
respectively.  The are grey or colorless.  Try
