Sparks,
Maybe you are the person who can explain this to me.

Where on the hysteresis curve is "choked"

thank you,

jeanna

    Not sure if I can answer that question.  What choked means to me is that the CHANGE in voltage at the supply is not passed through the circuit.  The impedance of the circuit is such that the selfinductance of the coil core combination  results in no  current passing from one terminal of the supply to the other.  The change in voltage at the supply is completely absorbed in changing the magnetic field density within the core of the coil.  The counteremf is equal to the forward emf.  The magnetic field density changes though.  This creates a magnetic circuit that in ferrite does not result in setting up magnetic domains and retaintence and hysterisis  but causes a precession of the atomic magnetic moments.  It just makes the atoms wobble instead of roll into alignment.  This magnetic precession is fast and allows the ambient magnetic field to realign the magnetic field of the ferrite upon cessation of the magnetic current within the core material.

i'll also see if i can get a picture of my high voltage circuit lighting up an incandescent bulb with one wire and no spark gap...
OOO wilby I really want to see that, please!

@Sparks,
thanks.
It helps a little.

will

more .!

show what ever you like !

i would love to see your pics! 

im still ripping junk apart ... 

you all never seen so many special caps and inductors and tuned coils ... i garentee it ...  and all i do to make some scary crap ...  wind a jt on the tuned coils ...  find a sweet spot lol 


ist!

i found SOME SPECIAL 1000V CAPS ...  : )   LITTLE RED ONES ...
To understand the action of the local condenser E in fig.2 let a single discharge be first considered. the discharge has 2 paths offered~~ one to the condenser E the other through the part L of the working circuit C. The part L  however  by virtue of its self induction  offers a strong opposition to such a sudden discharge  wile the condenser on the other hand offers no such opposition ......TESLA..

THE !STORE IS UP AND RUNNING ...  WE ARE TAKEING ORDERS ..  NOW ..   ISTEAM.CA   AND WE CAN AND WILL BUILD CUSTOM COILS ...  OF   LARGER  OUTPUT ...

CAN YOU SAY GOOD BYE TO YESTERDAY?!?!?!?!
