The B-H curve in an Inductor - Charges in Caps
Here are some thoughts on inductors and capacitors.
The equations people use in electronics for resonance and reactance are for the steady-state - linear situation only.
There is no accounting for START UP phenomenon. Nor is there a concern
about mutual induction -- which makes the calculus a bit nasty.
re: Inductors.
If they have a ferromagnetic material in them, they will
not be linear but will rather have a larger inductance
subject to the material's B-H curve. That curve, however,
is gotten again in a very steady-state, closed-system sort of way.
The B-H curve is useless when MUTUAL induction is in the picture.
If the inductor is subject to other flux fields from other magnetic
field altering devices out there, your coil's inductance is a bit
tricky to determine.
MagAmp designers knew how to do this -- a lost art.
Interestingly, when inductance increases, the resonance frequency
changes as well (going lower). The power output is altered depending upon
the input frequency. So in this way one can have a GAIN or a LOSS
depending upon the flux set up in the coil from outside influences.
With two COILs (or more), the mutual inductance can make things
quite complicated ... almost like a chaos system with initial conditions
resulting in bounded chaos.
re: Capacitance
C = Q/V
Who is to say that a capacitor device MUST get its Q (charge)
from ONLY the circuit. If C is to be held at a constant,
if something outside the capacitor (and outside the circuit)
was able to inject into the capacitor additional charge,
the V value would need to rise proportional to Q to maintain a constant
C. The capacitor has a physical limit as to how much charge
it can hold -- a function of its geometry -- which will dictate how
high the voltage can go (or how many Joules can be held in storage).
One could imagine a capacitor that has the plate connections for the circuit, but also interfaces with a source of charge arriving to it from OUTSIDE the circuit -- charging it.
If you have a large enough surface area, the particles from space will gradually charge your capacitor. This is well known.
If you had a magnetic vortex that focused charges down to your plate, like a magnetic tornado, your capacitor should charge up faster.
Enter the Coilpacitor
Why not have the capacitor be INSIDE the coil?
The coil is a nice source of spinning magnetic fields when operating.
The capacitor can have plates that are exposed to these fields.
These two devices seem made for each other and should be married.
A coilpacitor would be a non-linear device. The more current you
put in your coil, the larger the magnetic field, which could convey
a larger charge into the capacitor.
If they are used as a traditional tank circuit, the collection of
charges by the capacitor, given to the coil, can help with the
collection of more charges, and so on up to some equilibrium point.
LRC
If such a coilpacitor tank circuit could be constructed with a very small resistance (superconductivity?), it would do more than RING forever.
Its power would BUILD, regeneratively,
because all charges collected would be added
to the resonant wave -- building it in amplitude, larger and larger.
Resistance is the LOSS of charges in the system due
to heat or mechanical vibration or other energy expressions such
as mutual inductive drag. If the charges entering the coilpacitor
can be balanced with those being taken away to run a load
and due to losses, the system reaches equilibrium w/o violating
any laws of physics.
Someone analyzing a circuit with a coilpacitor or other complex mutual inductances & charging in their system might conclude they have so called "negative resistance" -- as they try to think of the system using
the MATH that assumes a more simpler-linear-steady-state system.
