Re: How does voltage rise

Original poster: jdwarshui@xxxxxxxxx

Hi: chip

Yes you can make fully enclosed primaries, but you will find (as we
have) that they behave no differently then a localized primary.

If you feel for heat from a cylindrical primary you will find that
there is localized warming at the geometric center. If you mismatch
this geometric center with the geometric center of a half wave
secondary you will find a quick drop in performance. Also you can feel
for heat on the secondary and you will find that it is also at the
geometric center. Thus primary location is a part of boundary
conditions, it is a focal point for the nucleation and transfer of the
EM waves from primart to secondary.

Clearly there is a concentration of magnetic flux where the
(conduction) current is greatest, and the (conduction) current will be
the greatest where the localized heating is found, as the heat is a
manifestation of  I sqrd R loss.

Loosely coupled standing wave resonant transformers are not at all
like ordinary iron core type transformers the turn ratios have no real
meaning here. Voltage rise is instead a product of resonance.
Magnifiers and some solid state systems have very tight coupling, turn
ratios may have some significance for these devices

The classic series LC circuit shares the same mathematical solutions
as a mass spring arrangement so we can view an inductor as a mass and
a capacitor as a spring, but this is only a mathematical game. The
transfer of energy across an inductor does not depend on the flow of
electrons but on q,  dq/dt and d2q/d2t. (acceleration in the mass
spring world is directly analogous to the second derivative of

If you want a realistic view of how standing wave resonance works you
can read about rope resonance. This will give you a good understanding
of how waves transfer energy and what impedance means.
