Magnetically Coupled 3 Phase Idea

[The Flavored Coffee Guy]

I was looking into magnetically coupled plasmas, and really don't like
the obstruction that a coil presents to viewing the plasma. Honestly,
I rather break out the welding goggles, and look.

But, I got the idea from the Tesla's Columbus Egg, and 3 phase
electric motors, as well as super position, and destructive
interference. Basically, the three phase forces the magnetic lines to
loop outside of a toroid core. Allot like a solar flare produces a
magnetic loop except, you can't see it. That's superposition within
the magnetic core.

I figure, you could take advantage of that, and wind two RF toroid
cores to handle 3 phase AC. You could easily use a Johnson Counter to
produce AC at any real frequency, so long as the data latches you
choose can handle the clock frequency/oscillator frequency.

Powering up to toroid cores, with 6 windings each would allow the
direction of winding to place opposite poles in superposition ejecting
magnetic lines of opposite polarity. Just like the egg would rotate,
currents inside the quartz tube would rotate and reverse. A plasma
would serve as an eddy current's short circuit path. Managing the
average temperature of the plasma would be easier at lower frequencies
due to the three phase power always maintaining a certain number of
magnetic lines through the medium.

Heating would look more like the ripple voltage from a 3 phase
rectifier.

Heating takes place no matter which direction current flow takes
place, so the average temperature at lower frequencies should be
closer to constant below the ripple. It should be about as close as
you can get to using DC for heating a plasma while still using true
AC.

The real difference is that the quartz tube would be fitted through
the center of two toroids with a 3 phase winding arrangement.

It's just an experiment, but may prove functional in diamond
incubation chambers. Single phase microwaves don't lend time between
cycles for the plasma to cool, whereas you might be able to get away
with 60 Hz using a 3 phase system.
