What does the Magnetic Field really do to a Charged Particle?


Another Very Simple Experiment!
1: Take a Bifilar Coil, Tie both ends of one end of the Bifilar so the Coil effectively has one coil coming back on its self in the opposing direction if the Coil was carrying Current (Non Inductive Mode)
2: Setup and configure a Circuit so you can see the Charge Time of the Coil maybe with a sense resistor. (See below Circuit)
3: Now measure the time to charge the Coil in Bifilar NON Inductive Mode.
4: Note the time down.
5: Now change the Bifilar Coil to Inductive mode series Connected so as to keep the same Resistance of the Wire as in the First Experiment.
6: Use the same Circuit and measure the time to Charge the Coil.
7: Note the Time.

Inductance!
Because the Inductance has changed between the two experiments but not the Resistance we can see a huge difference in time to charge the Coil!

Inductance (Directly Related to the Magnetic Field) has made it possible to charge a Coil that is effectively NON inductive at a Much Faster Rate! This allows the Charges I.E: Current, to move Much Faster!

Conclusion:
The Magnetic Field produced by a Charged Particle is directly proportional to the Rate of Flow (Speed at which it can travel) of the Charged Particle. E.G: the Magnetic Field that is produced by a moving Charge slows down the Charge itself.

All other diagrams show the winding polarity in a "flyback mode" where the maxima and zeros of the currents do not occur simultaneously.

Hi Verpies,

I believe once these Coils are Understood and once the Current and Voltage Measurements are done when in operation, they will prove to be quite different than the picture you posted. There will be a debate on the dot notation and what it actually means for this arrangement.

Its not conventional Transformer theory, not entirely anyway. Phase Angle and so on are not a concern, Pure, raw power. Lets just leave it here for a while before I overstate this whole thing!

All the Best

I believe once these Coils are Understood and once the Current and Voltage Measurements are done when in operation, they will prove to be quite different than the picture you posted.

The schematic you posted is limited to MOSFET's duty cycle from 53% to 100% because the signal at the MOSFET's gate is inverted in relation to the output of the NOR gate inside the TL494.  This also gives the TL494 a ridiculous positive PWM feedback loop.

Think about it - I'd like to know if you still insist that the schematic you posted makes sense.

Anyway, below are two REAL scopeshots with the transformer in Akula's circuit v3 connected in the "normal" transformer mode and in flyback mode (Ch1=Gate voltage, Ch2=L1's current, Ch4=L2's current).

P.S.
I can't open Grumage's rar file but I can see the schematic that he had posted in his first post.

Yes and such bucking/opposing bifilar non-inductive winding has a very high yawn factor with its high di/dt.

After such bucking coil is "charged up" for a short time, it cannot be later reconnected to an aiding mode and be expected to discharge for a long time (low -di/dt), because the bucking mode prevented any magnetic flux buildup in the core in the first place.

(snip)....
In the Picture below, you will be able to see that there is a Polar benefit and Bipolar Switching is not the best with these coils. I was hoping someone would have seen this already.

All the best

It appears that you are using AC-coupling on both channels of your oscilloscope. The little sine wave symbol next to the channel vertical attenuation settings indicates AC-coupled, if I am not mistaken. Is there some reason for that?

Your scopetraces, which are labelled Input Voltage and Input Current.... are only showing the ripple or switching transients which are sitting on top or bottom of the true signal voltages, because the use of AC-coupling has removed any DC or non-varying component of the signal. Hence any math performed on those traces will be incorrect, unless you know and use the value of the DC offset that has been removed by your choice of AC-coupling.

(I'm not challenging your basic conclusion or interpretation.... yet.... I'm just wondering about your scoposcopy.)
