Perhaps I misunderstood. Are you suggesting using the magnets from
a magnetron in place of an output torroid?

Just in case this is the idea, I have a few concerns. First, the output
torroid of a TC is supposed to be a capacitive load on the circuit.
Capacitance is directly proportional to area, which a mag magnet doesn't
have much of. Second, a mag magnet has a strong magnetic field which
will defifinately influence the E-field of the resonant circuit.
I can't say that this will not work. I can only say that you would be
going against several of the accepted parameters of an output torroid.
This might possibly work better than anything anyone has ever tried. I
look forward to reading of your results, should you decide to try it.

Good Luck!
