The Master Of Magnetics "Steven Mark"

Hello  I have some questions for the group

Why did SM use bailing wire in his first device?
Was it the core of his output coils?
or was the bailing wire part of the current path?

I have seen the video with the coil being sawed open, they cut out a pie shaped section of a medium size TPU. You can see two coil ends with what looks like a wood section in between and the output coils wraped around toroidaly.
The scroll saw used to cut the unit open cuts through pretty easily so any metal used in the device must be soft.

Could someone give an idea of how the coils might be configured in a schematic type drawing?

Thank you
Mike

Who is performing the experiment in this picture?

It is from George Woynar?s group, who are also trying to replicate the
Methernitha Testatika.

Where did you see this video? I've been unable to find it. Stefan used to have it in the old harti.com/coil site, but it's not moved over here yet.

Here are still a few more videos:

Bob,
Try a hot soldering iron!
You will be amased!

I have, of course, already tried a hot soldering iron otherwise I wouldn't be using sandpaper!!
I have an 80watt variable power supply weller so plenty of juice their.
I got the wire from an army surplus store a few years ago so possibly has some high temperature coating.

I'll try my gas cooker to burn it off.

You use a lighter and hold the wire in a wet towel so that only the end is burned. After burning that you clean the ends with alcohol and a cotton-wool tip.

perhaps it is also possible to remove the lacquer with acetone!?

Hi,

Though it was a long time ago I did the following to clean the end(s) of Litz wire:

-Use a lighter and burn the end of the Litz till the textil is burnt and the wires get red hot (a few seconds)

-While red hot, suddenly put/dip it into spirits (denatured alcohol) you provided in advance in a very small dish near to you  (if you have no denatured alcohol I think normal +90% alcohol will do)  Be very careful not to light the alcohol in the small dish!

-Now use (multicore) solder wire (which includes resin) and the tiny wire ends should get nicely tinned by using your normal soldering iron.
