Flat spiral coil
by Alexander V. Frolov
In 1990-1997 author investigated some Tesla's ideas
and it was found possibility for asymmetry in mutual-inductivity between
primary and secondary coils of electromagnetic transformer. When the primary
coil is a solenoid type coil but secondary is a flat spiral coil, there
is very small induction (reaction) from secondary coil. It means the load
can be connected to this flat spiral coil almost without contra-flux and
contra-EMF (electromotive force), i.e. it is almost free of primary source.
Sure, real system allow to get some asymmetry but it is not 100% free load
Power in load is limited and it is depend of magnetic
flux changes and coil parameters. For powerful system it is possible to
design output power value in several times more than input power when it
is the resonance state circuit.
Any proposals for reproduction of this effect
in your laboratory are welcome! Ask me for calculations and design example.
