Thane Heins BI-TOROID TRANSFORMER

Blue one is half a Ferrite toroid, black one is a whole MetGlas toroid.

The original idea came from Paul Lawrence.
He calls it his HUE device.

Below picture represents my own build, under investigation right now.
There is another winding on the other side of the MetGlas core.

Hi teslaalset,

Can you measure the coils inductances? I am curious...

Thanks,  Gyula

Measured with a Voltcraft LCR-9063 multimeter, I got:

5 mH for the coil with the ferrite core
50 mH for the MetGlas core ones

But, remember you can't just measure coil values assuming those values are fixed.
They vary as a function of current fed through the coils, changing the H value.

Thanks. 
Yes I am aware of changing inductances when driven over certain excitation levels.  Especially if you pulse them (switch DC voltage source across the coil by a controlled switch). 

Will you drive it with sinusoidal AC or with pulses I wonder.

Gyula,
I will try both.
To get the best out of the device, it's best to use both positive and negative currents, or at least vary magnetic flux in both directions of the cores passing the H_c values of the coils.
Only then the maximum values of mhu's can be optimally used.

Ok, I agree, thanks.
