Metric magnet wire (enameled copper wire to you) is usually specced in diameter, rather than cross sectional area.

durable; the other is a cheaper thing, but the moths get into it."

"About 12 gauge" is hardly an engineering statement. Didn't they use a micrometer?
Possibly 2mm diameter.
(maybe slightly
#12 wire is 2.053mm dia. #10 is 2.588.
Best practice would be to wind for the same number of amp-turns as before.
From wire tables, changing from #12 to #10 wire,the resistance of the same number of turns will decrease by a factor of approximately 0.6. The current will correspondingly increase by a factor of approximately 1.6, hence so will the amp-turns, assuming the supply voltage stays constant. How much the strength of the magnet will increase depends upon the magnetic properties of the magnet iron. If the magnet was originally operated close to saturation, the increase in pulling strength may not be very much.
The power dissipated in the copper is proportional to current squared, hence 1.6 for the same voltage. The coil will run hotter.
There's also the issue of supply regulation. Will the transformer supply the increased current without significant voltage drop?
Why did they rewind it using #10? Didn't they have any #12? I'm surprised they didn't have metric sizes, there are a lot of Japanese and European motors around.

Now you're just teasing the donkey, who can only count to four that way...

You're wayyyy off base...

No, my position is pretty safe.

The USA is 'supposed' to be metricated. hy you choose to be so backward never fails to amaze me. Any given wire gauge covers a wide range of cross-sectional areas. At least you know what you're getting with mm2.

It is indeed. AWG does not specify an explicit conductor CSA.
TOTALLY universal except for the USA, Liberia and Burma / Myanmar, both somewhat backward countries you have chosen to retain compatability with. Some might say the USA is rather backward too. The high level of belief in religion is one pointer to that.
understand
Conversion is a waste of time and a source of errors. There is only ONE system of units I need for engineering.
And what did you get from going to the Moon ?
Furthermore we have ESA
It knocks spots off GPS.

Oh dear ! Is that how it was specified ? At what temperature btw ?

What an absurd comment. Do you have 12 fingers so you can count in inches to the foot ?

LOL ! Give me a thou over a 'mil' anyday. Only the Americans could confuse a metric prefix with an old unit.
Not to mention that if you use the word 'mil' in the UK it means a millimetre.

I didn't go bonkers at all. I just picked an easy target to stir you up.
We can convert too, you know. Thankfully only an issue for you lot.
Why don't you use it ?

Yes, we use the binary way!

AWG does not specify conductors. It specifies *wires*. There are other types of wire than electrical.
