Bifilar wire

[z.monkey]

Howdy Prometei,

I have never experimented with winding wire on a wire.  Usually the core is composed of a ferrous substance and the wire is not.  In the case of a guitar string, the inner and outer wires are shorted together, so it would probably act as a single conductor.  With the bifilar windings, the two connections are on one end of the coil, and on the other end the two wires are connected together.  The coil in my notes will work better than then the bifilar coil with a ferrous core because there is no bucking in the core.  If you use an air core then the bifilar coil will work better.  I'll send my notes tonight after work...

hello folks

So electron spin is an important factor to take into consideration when dealing with coils, how about the cables that connect the batteries to the circuit?

I got rid of the alligator clip leads and made me some DIY cables with gator clips, I've used regular household 230V power cable.



Do you think it would be better if I separate the positive and negative leads?


p.s. z.monkey thanks for your email, I did not read the notes yet, maybe they would answer my question.....

Howdy,
The electron spin considerations only come into play when you are dealing with inductors.  When you are dealing with wire that travels in straight lines, such as power supply cables you don't have to worry about that.  When you are trying to magnetize a core the orientation, and placement of the wire is more important.  Having good power connections is important.  You are using alligator clips there.  You can buy crimp terminals that fit the battery connectors perfectly so you don't have to worry about that connection.  Then use a switch to connect and disconnect the battery.

That's a good looking setup there Prometei.  I can't quite see the rotor but it looks like there is a resin wheel with magnets embedded in it.  Kind of looks like a one cylinder Bedini setup.  Does it run yet? 

Looks cool...

Good Work...

Hey tanks. Well my leads have kroko clips on one end and crimp terminals on the other. And ye the motor runs. Here is the topic I've started with more info and pics

I have begun building my own spool spinner for in-house manufacturing of twisted pair stainless fine enamel coated wire to be wound according to Stan Meyers VIC bobbin core. I've added a description, more photos and videos to the link above. I hope to break this barrier and make twisted pair capability available to hobbyists like myself, also a retired NASA contractor. Thanks, Ron
