John, from your circuit, if you change the direction of current in the
coaxial conductor through the ferrite ring, nothing happens. Why
should it?

The only thing worthy of consideration is your determined persistence.

As I have said before, as may be gleaned from other contributors, you
are in good company.

Beware, the amount of effort the old wives are putting into it might
give you the impression it's worth while making a patent application.

On the other hand, what with the state of expertise in the Patent
Office, you may possibly succeed. But you will never get rich enough
to recover your legal expenses.
