Very interesting experiment. How were the coils excited? A large primary coil?
A primary for each one? Note that even small differences in the coupling
coefficients or in the resonance frequencies of the coils can cause their output
voltages to be at opposite phases periodically, what explains the sparking in all
combinations.
