Paul, The florists wire I have here is galvanised steel.That explains the magnetic attraction and reluctance to rust. It also explains why it will allow many bends without fatigue like pure aluminium.
Of course there may be numerous types of florists wire, I suspect I know about as much about this, as the average florist knows about magnetic induction.

I had reason to build a couple of small induction coils, and I ran out of the 16 iron wire I usually use for the cores. While in a craft store I found packaged length of wire made for artificial floral arrangements. It was 18 gauge, so that was OK. I tested the wire with a small magnet and it stuck, so I bought some. At home now I'm not sure what I've got.It's white metal, and rather soft. Seems like aluminum, but it is attracted by magnets. I left a short piece wrapped up in soggy paper towels for a day or two, but it didn't rust. If it weren't for the magnetic response, I'd swear it's aluminum. Some alloy, I guess, what is this stuff?PS I made a core out of it; it works, but the magnetic field is weaker than when I use iron wire . . .PBT _______________________________________________ Tesla mailing list Tesla@xxxxxxxxxx http://www.pupman.com/mailman/listinfo/tesla
