Re: [TCML] Flat Spiral Primary

[Mike Thompson <mthompson14@xxxxxxxxx>]

Well the question pretty much came out of my trip to Lowes last night. I walked around a bit to look for materials. I noticed that I could get 20 feet of 1/4 inch copper tubing for 17 dollars or 50 feet of 9 gauge galvenized wire for 8 dollars.
 
I did not see any bare 10 or 12 gauge copper wire in my travels (Guess I'll look at Home depo instead).
 
Would the iron wire being ferrous have any affects on the wire's DC resistance? How about inductance values?

I was wondering what some of the draw backs of using 9 gauge galvenized fencing wire would be. It is cheaper and I get twice as much wire for half the price of copper.

What about using AWG 10 or AWG 12 bare copper wire?  Galvanized iron wire is pretty high resistance.  But you can do the calculations and see.
