Thanks for the help. For some reason, I thought that if you could rotate a secondary out of phase, it would lead or lag, Instead, i hit me that it would decrease the amplitude...
Vout=Vsec*cosθ, where θ is the relative angle that you rotate the secondary.
The only way it would be possible without using moving parts would be to use 2 pieces of ferromagnetic material which are timed correctly behind and forward in the space-time continuum... or something like that
