One can always count on Naudin making professional videos.

That's because your cores are a lot bigger, and contain ~ 4.5 times more material. I posted the calculation at this forum like last month. If works about the same price per amount of material.

I bought 30 @ a little over $4.00 each.
Just back from week vacation, trying to get over it.

This is a "static" curve (no external magnet moving effect) just the coil and the core.

The "dynamic" curve (with the magnet approaching to the core) is more large because the saturation due to magnet effect.

my feeling is that the saturation curve change is similar to the enclosed picture.

The gain of energy must be find within the change between the two condition "no load=no magnet" and "shorted=with magnet".

Moving anti clockwise between the two curve (having the contribution of the moving magnet) you have OU.

Naudin great men.
It show us the beauty of the symmetry.
Without symmetry the B-H curves have the Y axis shifted on one side and you have easy saturation of the core.
Probably it cannot be compensated by bias current because you reduce the attracting effect.

Hey Bill,

Ok, having a shorted winding on the primary does indeed allow the current to flow, and reduces the need for much voltage at all.  I have just burned up some wires (too much current), no biggie... LOL  But I now must switch from my 12 volt sealed lead acid to a D Cell and see what happens.  Worst case, I put it onto my power supply.  I really want to go with a battery if I can.

Shorted secondary (my green winding) is not connected to anything but itself (shorted)

Bruce,    I noticed Naudin uses a  Booster coil approach.    I wonder which would be best?

Hello all,

Do you know what hides in the sheath blue?
Test JL Naudin : http://jnaudin.free.fr/steorn/html/orboeffecten.htm

Is this the modification for an auto-transformer?


Does somebody have the diagram?

Thank you for the answer.
