ENERGY AMPLIFICATION

"Measure the distance in centimeters between the electrodes in the spark gap with the ruler. For a spark plug, slide the gapping tool into the gap until it fits snugly, then read the gap distance on the tool.

Key in the number of centimeters into the calculator. Press the multiply key. Enter 30,000. Press the equals key. The result is the voltage required to produce a spark in the gap. For example, if you measure 1 millimeter, first convert to centimeters. At ten millimeters per centimeter, you'll have .1 centimeter. Multiply .1 by 30,000 to get 3,000 volts".

It looks like Magluvin's setup is generating "Stun Gun" mega range voltage! I bought a solid state 12 volt to 500,000 volt transformer from China that works that way.

The limitation to this circuit is the lengthy charge rate of the primary capacitor and the low frequency of operation. My transformer operates at or below one 1 Hertz frequency. The "Gray Tube" predicament.

In my vids I used a capacitor bell ringer config on the relay to create a purposeful time delay so for each spark event we could see that there were multiple sparks in the conventional points circuit, using an actual points condenser to enable the coil to oscillate as an LC once the points open. I can change the timing for much faster spark events but the pics and vid would show it more like a stream wandering around the spark terminals. The large inductor as long as there is periodic (points closed) current, it basically keeps conducting in the same direction throughout the  operation period at faster switch losing speeds. The large inductor is not like 5kohm. The one in the vid is 46ohm compared to 1ohm spark coil primary. So once the circuit is going, the inductor loads up the caps pretty quick.  Its a .2uf ignition condenser used for the standard points circuit and the Igniter circuit. At these freq shown would be very low rpms compared to an actual spark timing event on an engine, so the inductor is charging the cap to full potential before the spark event occurs. When it gets up in freq, the inductor is conducting more continuously. Without the condenser in the standard circuit, the spark is 1 thin pip only sometimes.  So possibly many guys that just go with electronic ign modules in place of points may not know that the condenser was bad. Both the original point system with a good condenser and the Igniter circuit produce real multiple spark ign due to resonance of the LC in each case. The main difference is the 46ohms of the large inductor in series with the 1ohm spark coil primary.  So that reduction in current compared to the standard points circuit that holds 12v batt across the spark coil primary at 1ohm for a longer period that the points are open is big. So calculate the input power for each case and that is where you see the advantage of the igniter circuit. In my measurements the cap in the standard circuit reaches near 100vac when in oscillation with the primary when the points open. So the igniter circuit, you find a large inductor that will charge the cap to near 100v then when the points close, that charged cap is across the spark primary giving virtually the same conditions to produce the nearly same oscillations and spark, but for a small fraction of the input in comparison.

a magnet in the core of the large inductor should amplify the flyback charge to the capacitor like brad's magnet core coils.

a magnet in the core of the large inductor should amplify the flyback charge to the capacitor like brad's magnet core coils.

Using a magnet to bias a coil makes the coil act differently depending on the direction of current. If the current creates an opposing field compared to the bias magnet, the coil will have to produce more field strength before reaching saturation. If the current is in the other direction where the coils field is in attraction to the bias magnet, the coil will reach max current sooner. Sort of a say soft rectification action.  There are magnet biased cores(example Hitachi) that the magnet added allows the coil to store more energy with a smaller core. Like a simple boost converter switching supply. There is no extra energy by adding the magnet. It takes more input to reach that new upper level of energy stored, same as with a larger core. When the magnet is biased in attraction with the coils field, the coil sees a much quicker saturation due to the 'added' magnet flux that already exists..

"The use of permanent magnets for introducing bias magnetization in DC inductors is a known technique for extending the saturation current limit and accordingly reducing the required inductor´s size".

So the flyback is amplified because the coil stores more power with the magnet, and we pay for the amplification with additional input.

Nevertheless, the magnet should add power to the spark!

Have you thought about coupling the Igniter with a "Gray Tube"?
