I agree. We could in the early days.

Here is a tip.
If you are replying to many things you can use the quote button, but you kind of need to watch the tags or the whole thing will be incomprehensible.

I like to push the button that opens the link in a new page. that way I just need to move the current page out of the way to read the thing I am replying to. Sometimes it can get nuts. tonight I have been posting on 4 threads. nuts.
Are you using firefox?

From Wikipedia:

Magnet wire or enameled copper wire is a copper or aluminum wire covered with thin insulation. It is used in the construction of transformers, inductors, motors, headphones, loudspeakers, hard drive head positioners, potentiometers, and electromagnets, among other applications. However, it is not usually magnetic itself.
The wire itself is most often fully annealed, electrolytically refined copper. Aluminum magnet wire is sometimes used for large transformers and motors. However, because of its lower electrical conductivity, an aluminum wire must have 1.6 times the cross sectional area as a copper wire to achieve comparable DC resistance. Smaller diameter magnet wire usually has a round cross section. Thicker magnet wire is often square or rectangular (with rounded corners) to permit more efficient use of available winding space. Older insulation materials consisted of cotton, paper, or silk and were only useful for lower temperature applications (up to 105°C).


Hope this helps.  Don't feel bad at all.  I have learned so much here AND I also learn something new at least once/day.

Bill;
I DO feel bad.  I feel like an IN-complete idiot!  I have ALWAYS thought all copper was magnetic!  Now I see it is NOT.  I also just looked up the meaning of the word and it says:
magnetic wire definition
a fine wire of a ferromagnetic alloy, used as a storage medium for magnetic recording

ferromagnetic definition
ferro·mag·netic (-mag net'ik)

adjective

designating a material, as iron, nickel, or cobalt, having a high magnetic permeability which varies with the magnetizing force

So now I need to look for the real stuff before winding any more secondaries.  Thanks for the info and for not laughing at me.  (you didn't laugh at me, did you???)

I should have gone to bed hours ago, but then I wouldn't be having all this fun!!  And besides, I am learning...big time now. ha ha.
Okay, so SOME copper wire is magnetic wire...some aint (aint...means "is not")

Here is some info I just located on magnetic wire.
Copper mag wire is used in OIL IMMERSED TRANSFORMERS AND OIL FILLED MOTORS.

Aluminum mag wire is used in HIGH FREQUENCY TRANSFORMERS, COILS AND INDUCTORS.

So, even though some copper wire is mag wire....we had better use the alum mag (or even iron mag if there is such a thing) if we want our COIL to work properly.

Maybe my ignorance will be showing here but, what the heck.  My understanding is that it is called Magnet Wire, not Magnetic Wire.  It does not have anything to do with being magnetic.  I have no real idea why it is called this but, it is.  Copper is never magnetic under any conditions I have ever heard about.

Forget magnet wire...just think of it as (like the Wiki thing said) enameled coated copper wire.
