Hi, this may sound pretty basic, but I've read books all the way up to RF communications so I'm not ignorant
about conventional theory, but I do like to revisit basic concepts from time to time to see if anything is being
missed.
So the notion is that a transformer can step up or down current or voltage based upon turns ratio between
primary & secondary, and of course we know this is true, however:
Radio theory presumes (and devices prove) that magnetic fields radiate off into space for quite some distance.
We can consider magnetic fields as individual closed loops that excite electron movement in the wires they cross.
I prefer to use RF coil in this example vs. a closed-loop iron core transformer.
Imagine a hollow plastic core tube upon which a coil of wire is wound, and through which RF energy will be pulsed.
Imagine also, a secondary winding of same wire thickness and number of turns. Then imagine a third, fourth and
fifth... winding, similar to the secondary, all layered over the primary. Imagine then all of these secondary coils,
each of equal number of turns as the primary, wired in PARALLEL, such that when the primary winding is energized,
all the field lines cross ALL of the secondary coil(s) windings.
Now in terms of a single secondary, we would assume energy in primary = energy out secondary (with minor losses),
however with multiple secondaries in parallel, I'd like to know why the expanding and collapsing field lines wouldn't
be additive, i.e. the energy manifested in the first secondary would appear in equal magnitude in all secondaries.
In other words, the energy input into primary 'z would equate to 'z times (N), where (N) is the number of secondary
coils, again assuming they are of roughly same dimensions, turns, wire thickness, and concentrically wound, so that
primary field lines cut all secondary coil(s) windings. Since the primary and secondary windings of equal turns, 'see'
the same voltage, why wouldn't current be amplifed by and within the sheer greater surface area of the secondaries?
I'm assuming that field lines don't weaken just for cutting more copper.
