really stupid question.
« on: September 25, 2013, 08:49:37 PM »
hello

I'm looking to get some laminated "magnet wire".

The instructions I am trying to follow are using the European metric system - i think.

So, the wire gauge is expressed as a ratio.

Can someone tell me what gauge "4/10 mm magnet wire" is in American AWG?

Thanks

You said    ""4/10 mm magnet wire" "

If that is meant to be 4.10 then it is  6 AWG

You need to know if it is  mm  or  mm2

4.10 mm   is   6 AWG
4.10 mm2 is  11 AWG

I attached two images showing the wire I'm looking for.

Each image has magnets and I give their dimensions as a frame of reference.

Can you tell me the AWG of this magnet wire?

Thank you.

Well that is nowhere near 4 mm so it must be   4 tenths of a mm  or 4 tenths of a mm2

If it is 0.40mm it is     26 AWG
if it is  0.40mm2 it is  21 AWG

it was written as "4/10mm copper wire".

Folks,  4/10 means  4 divided by 10   i.e. 0.4 mm  this is the outside diameter of the enameled copper wire.

from a web awg - mm tablet awg #26 corresponds to the 0.405 mm wire, so you can use #26 enameled copper wire.

PS carlprad:  your sentence in the first post "laminated" magnet wire makes no sense to me.  MAybe you meant enameled??

got it, thanks.

Finally, how do I figure out the right number of windings.

@carlprad
       I tried to count the number of turns next to the round 10mm magnet.   I got 14 or 15.   (The turns appear to be overlapped in at least one place on the toroid.)   Then I looked at an Internet conversion list of AWG diameters against mm in width for diameters.   If 15/10mm =  .66mm, then the wire is 22 ga---but it's not a direct correlation in diameters---my finding to the actual guage measurement.
       But, is the European nomenclature meaning "4/10mm" as equal to .4mm?   If so, the wire is 26 ga., which is an actual correlation.   26 ga. wire is .4 mm in diameter.
 
The wire appears to be that diameter in dimension on the pictured toroid.

Ok, so you agree with gyulasun, its probably 26 AWG?

Thanks

      Visually, on the picture, I'd say, "Yes."   But my question is:  Do the Europeans amongst the Members believe that  '4/10mm' = .4mm?
      I'm familiar with European wiring schematic standards by weight of personal experience.   The written description is something I've never seen, however.

Lastly, what is "0.1mm wire" in AWG?

And, yes, gyulasun you are correct. I meant "enameled".

Hi Lee,

Jean L Naudin has been using fractions for wire diameters for decades now. See here for instance:
http://jnaudin.free.fr/2SGen/indexen.htm 

Maybe the French use it, Germans and others may be not, it is more common to use 0.5 or  .5  formats.

carlprad:

from this link http://www.technick.net/public/code/cp_dpage.php?aiocp_dp=guide_awg_to_metric  0.1 mm wire is equivalent to awg #38
