Steve,

You will find a Ferrite rod in old radios. The ones that have the short wave band.
The problem today IS to find an old radio.

Hi All,

I must thank you all for your interest and your eager desire to start replication of Thane's more advanced Toroidal transformer. However before you all start taking your ceiling fans down for parts in search of the perfect core   please give me a day or so to give you more information.

Thane was going to meet Steven and I this morning with his toroid coil so we could take pictures, video and get up to date on what not do that he has already tried and does not work. However we had a big snow storm this morning and he could not make it into town since he lives outside the city of Ottawa. He has now invited Steven and I to go to his home in Almont to see the toroidal coils he has built allready and he is even ready to let us take them back to our home for testing.

Thane has been keeping an eye on this tread and sees we are a very dedicated group and wishes to help us succeed. So I will soon have much more information on Thanes toroidal transformer.

Hi Luc,

Your comments are dead on. His current devices will shed more light than sunshine.
Hope the weather improves!

Anxiously awaiting your info.

Thanks for your great efforts, Larry

@Steven: Thanks for the info -- looking forward to learning more.

Ok, I have confusion about the torroidal transformer too.  Most of my problem is due to the fact that my education is in Chemisty and IT.  Other than an EM101 and EM102 course taken several years ago I don't have experience with electronic systems.

Am I understanding correctly that the goal of the torroidal transformer with a primary coil on a higher reluctance core coupled to two secondaries on a lower reluctance torroidal core is to show that the back EMFs of the secondaries cancel each other out and do not affect the primary?

If so:
- What is the practical outcome of this design expected to achieve?  Reduce ineffeciencies of the transformer?  I looked at the wikipedia entry for transformers and it states that transformers are one of the most efficient electrical machines that exist--up to 99.75% efficient...  So would negating the secondaries back EMF and isolating it from the primary really make much difference in the transformers efficiency?
- In what ways would a toroidal transformer which has the back EMF of the secondaries cancel out and/or not affect the primary coil differ from or be superior to a regular transformer?

When I remember correctly Jean Louis Naudin
and also Mr. Frolov had on their websites a few years back devices simular
to a MEG or pulse motor or magnetic amplifier ( can?t find it now)
that also showed
decreasing input  when the output coils were shorted,
but this also was only impedance matching
as with open output coils the input power for
creating the magnetic flux was higher, as when the
output coils were shorted.
But never the output power was higher than the input power.

So the only thing the shortening of the output coils did
was to set a better impedance, so the input power decreased.

Maybe we have the same case over here ?

As long as the total input power is still bigger
than the drawable output power I don?t trust these circuits
although they are pretty interesting in their design.
