What is "magnet wire"? I have a test procedure I am trying to follow and it calls for "two strands of twisted magnet wire." I know it is referring to something like this: http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXHZW4&P=FR I know the transmission line characteristics of twisted wire and why one would do this when making a measurement but my question is: What makes "magnet wire" different from common insulated solid copper wire? This is the first time I ever saw this magnet wire term. I looked at this page: http://en.wikipedia.org/wiki/Magnet_wire And it seems like this is just a colloquial term for insulated solid copper wire because people often use this wire type when making various inductive devices despite all the details in the wikipage. Is this right or am I missing something important? If so, I get the abbreviation because insulated solid copper wire is a mouth full and repeatedly typing it kind of sucks too.
