The most recent problem was last week when a research student asked me for some magnet wire. Apparently this in the new name for what I've been calling enameled copper wire. I was then asked is that the same as transformer wire.

They use lots of different coatings including
ones that turn into flux for ease of soldering.

Which is normally called solder.

Or cotton.

constantine perhaps, which was used as resistance wire for making low value resistors usually less than 1 ohm.
we have a reel of that on wood and has been here 40+ years.

Or silk.

for posh people.

Or litz.

for brahms as litz peole aka drunk, I think this is used in headphone cables.

we have another sort which is karna(SP) wire it was used in older computer mainly mainframe for wire wrap connections.




He then asked me (looking at the label on the 35+ year old spool[1] of wire
why don't they put the diameter of the wire on the label and what does 38 swg mean.

Standard Wire Gauge. Next!
