[TCML] Bifilar Winding

["Phil Tuck" <follies@xxxxxxxxxxxx>]

Hello.

If a primary on a transformer was wound with 100 turns of bifilar magnet
wire, would you need to replace it with 200 turns of single magnet wire or
100 turns, to get the same volts per turn in the secondary (leaving aside
inductance & resistance issues)

Each conductor is surrounded by its own magnetic field, but if it is a
bifilar conductor is it surrounded by two?  

I have read that transformers use this arrangement to get better coupling,
but if 'better coupling' is the same as increasing the number of turns, why
not go down that route initially. You could get a larger gauge single
conductor offering the same lower resistance value, but taking up less
physical space on the former.

I've done some googleing on this but can't seem to find a definitive answer
solely for transformers. Most of the uses for bifilar windings are
inductance related. Such as resistors that are wound to cancel inductance
out, or else Tesla secondary's where inductance, self capacitance and
magnetism all come into play.

As transformers are concerned primarily with just magnetic lines of force,
the situation may be different to Tesla usage.
