Dave states regarding Rossi: “One thing is obvious, he likes to keep us guessing.”
I hope so… if he didn’t, we’d be really bored!

A steady state magnetic field will penetrate the stainless steel. A time changing one will be attenuated as eddy currents induced within the metal generate a reverse field that counters the source field to an extent that depends upon the rate of change of that field. The metal thickness is also crucial to the ultimate level of shielding. Mark, as you say the changes in the PWM waveform that occur at a slow rate will find their way inside. I am not confident that this is a mechanism that Rossi uses, but it might have some effect. It appears strange that Rossi does not wish to reveal the resistor drive waveforms. Perhaps he is using a moderate frequency drive signal for some reason that we are unaware of, only he knows. One thing is obvious, he likes to keep us guessing. Dave
