I see it like an amplification device,
Its a kind of LC having on the L side an air core transformer... so the LC circuit has a load which is the low mass electrons material since this is a short circuit it will load the primary.
When you get a short circuit in a transformer, the current flowing in the secondary has reverse direction to that current flowing in the primary so it creates a counter magnetic field, this is responsible to lower the inductance of the primary if the secondary is shorted,
But the point is: If the secondary has a lose coupling to the primary and this are air core one coil inside the other with a certain empty space between them (a gap), and then inside this secondary there is another coil but this very well coupled to the secondary than if the secondary has a counter magnetic field any induction in this output coil will have a non opposing magnetic field to the primary...
I guess the amplifier coil serves like a faraday cage since its shorted such that it has greater coupling to the primary than the output coil siting inside of the amplifier coil (secondary).
Actually i don't know why this should not work without this low mass electrons...
But the idea is the following
the ampere was determined using the electric current of 1 ampere and coils to create a force and ... this way they stabilished the magnetic field
But this was done using copper, the problem is copper has normal mass electrons and as such behave like other metals so the electron when have normal mass irradiate a certain amount of magnetic field...
If you think about what he says, the magnetic field increases when the coil has smaller turn diameter, why?
because this imply greater centripetal (acceleration)...thus more radiation of inductive photons...
But when this mass is not respected the electrons are allowed to have greater (acceleration) and according to lamour it will increase the magnetic field irradiated from it with the square of the diference in mass
so if the amplifier coil is acting as a shield as a load and as a primary
The primary acts as primary and L of LC network
The output coil serves as output and feedback coil to maintain it self sustaining oscillation.
