Hi Jared,

I don't mean to change the subject of this thread but
I've noticed that you seem to have quite a bit of
knowledge of different winding types. I wanted to ask
this question to the list but wasn't sure if anyone
would know what I was talking about. I've been curious
lately about bifilar windings. I read a website sometime
ago stating that this topology would create a greater
magnetic flux than a single winding. So I did a little
experiment, I wound two identical nails with two hundred
turns each of #28, one in the bifilar arrangement and the
other just a single winding. I applied 12V to each one
and noted how many paper clips each one would lift.
And as far as I could tell they were identical. Is there
some other quality that I'm over looking? Or did I
do this experiment wrong? The site said that the bifilar
coils were better for motor windings and such, do you
know anything about this? Any input would be helpful.

Thanks.
