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
4.10 it is 6 AWG
i don't understand.
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.

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.
--Lee
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 (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 (http://www.technick.net/public/code/cp_dpage.php?aiocp_dp=guide_awg_to_metric) 0.1 mm wire is equivalent to awg #38
k, thanks so much.

Here is a link to a freely downloadable software to calculate the number of turns, even for an unknown toroidal core. There other online calculators if you search for it like "toroid coil calculator".
Edit: added the link: http://www.dl5swb.de/html/mini_ring_core_calculator.htm

I looked at the Naudin page you posted.
Did you ever try his experiment?
I tested only the Motionless Electromagnetic generator i.e. MEG but never got any extra output higher than the input (I had about 87% efficiency). Naudin used non-linear (carbon based) resistors to load the outputs in the later MEG versions which made no sense whatsoever.
No I have not built the project in the link I posted to his site.
Gyula
I am new to all this and am basically just having some fun learning about all the incredible experiments you are all conducting.
When you say that Naudin used carbon based resistors in the "later MEG", do you mean the 2SGen, or some other MEG?
Thanks
Gyula
can you also repost the link to the toroid calculator, I could not find it.
Thanks
I mean that till MEG version 2.1 he used correct, non inductive resistors see the first half of this link: http://jnaudin.free.fr/meg/megv21.htm (http://jnaudin.free.fr/meg/megv21.htm)
but later on when he referred to his MEG version 3 (in the bottom half of the link) he used a "conditioned" 100 kOhm carbon resistor which has a non-linear property of changing its resistance as the voltage changes across it... or he suggested using a MOV as the load which is also a nonlinear (metal-oxid varistor) component...

yes I inserted now also above, sorry http://www.dl5swb.de/html/mini_ring_core_calculator.htm
oh, I see.
You are not referring to the 2SGen then?
By the way, can you give me the link tot he toroid calculator?
Thanks
got the link, sorry!

@gyulasun
Good to hear from you.
I did see reference to the wire diameter wording in jnaudin's site above. Interesting. Whether or not he's alone in writing wire diameter descriptions that way is open to question. Others in his country may take exception to his wording if they were really unfamiliar with it. Those who research both European and American wiring schematics would immediately see significant differences in component identification symbols. Capacitors are an obvious example to me.
