Do you need special wire for macing inductors?

Exsample:

13 thurns of 22 gauge isolated wire orund...

What is 22 gauge isolated wire?

I think isolated means insulated. It depends on the frequecy that the inductor is being used at. Most inductors are wound with magnet wire, which is solid copper wire with some form of enamel on the wire for insulation. At low RF frequencies Litz wire is used. It consists of very small diameter(large guage number)with many strands in parallel. This helps reduce the self capacitance of the coil. I have used solid hookup wire with insulation, and have used buss bare wire for other applications.
There are times when silver plated wire is used.

So can i use a wire from a motors coil?(for 22)

I can't see how Litz wire can reduce self-capacitance. Litz wire reduces skin effect resistance. This allows inductors to be made with significantly higher "Q" than is possible with single-strand wire. See this site.

Well the guage of the wire will bemthe thickness of the wire. 22 sounds like it is in the American Wire Guage format

I found this site when I first had to use AWG (and all our stuff is in metric)
I have printed this off and stuck it behind our cable rack so all can check when needed

This isolated remark??? Do you mean insulated.
And finally what are you using as a former?

Ron H is correct. The statement I made about Litz wire is incorrect.
"This helps reduce the self capacitance of the coil". I should have said it
increases the "Q"

Its a air core former(round ufcourse).
