Think of this you have a primary and a secondary...
the primary is applied a pulse... the secondary has connected to it a choke and a dc source..
(air core)
the primary lets say sends a north to the secondary and the secondary is already polarized with north agains the primary north.
The primary wants to induce a voltage that is going to increase the north already in the coil like increasing the repelling force intentionally, because supposedly its going to make the induced voltage or current output in this coil to be greater...
It becomes very obvious to me that something is strange about the polarity of the coils stanley meyer used,, maybe he was exploring this effect.. .
