The current in this video travels through the LED to charge the capacitor, it dosen't "Dead End" there like MH implies: The opposite field change from the inductor collapse is graphically depicted at 5:20 in the video.

"The inductor changes the directions of electrons, the capacitor does not. Lets say the capacitor has just given all its energy to the inductor and it is the positive peck. Now the inductor has the energy and now the magnetic field starts to collapse, the electrons change in direction, but the potential is still positive for awhile but it is going negative.

At the positive peck and the negative peck is when collapsing magnetic changes the electron flow, not the potential right away. It is like pumping water up hill through a pipe into a tank. Then the water is allowed to run out of the tank back though the pipe in the opposite direction. It takes awhile for the energy in the tank to change (potential), but the water (electrons) changed direction right away. And that is why it is call a Tank Circuit".

I suggested to Conradelektro that he try and build this simple reed switch bemf feedback to source spinner to test my "Synchro coil". I plan to try it when I get home. The idea includes a bifilar power coil with one loop for output in series with a second fast switching diode and electrolytic capacitor, and of course a stack of coupled diametric magnets inserted into the coil core for the additional Lenz free "Magnet pumping" type power.

I have found similarly that coil field collapse can happen in forward direction 'or' backwards.

From what is known, when we switch on dc to a coil then switch off, the field collapse causes more forward current from the coil. But what I had found a couple years ago was that if there is no where for that forward collapse current to go in the forward direction, then the field collapse charges the coils self capacitance to peak, and that stored voltage bounces back through the coil causing a reverse current and field.

I call it field collapse because Back/Reverse emf doesnt really apply during initial field collapse because the resulting current is forward and has nothing to do with a field collapsing on the coil that made it. BEMF has everything to do with impedance of a coil. The gradual field building of an inductor is due to Reverse emf due to currents building in the coils windings, which all the windings are inducing all the others at the same time and the induced windings want to push current in the opposite direction.

The only thing I can figure about how coils do what they do is because of resistance. Due to resistance, the voltage/current applied to the coil will always supercede the back/reverse emf and the input will eventually win the battle of fighting the bemf till the bemf does not exist and current from the input gets to its maximum due to resistance.

Soo, if the coil were super conducting, zero resistance, I believe the coil would not pass current at all as the bemf should be equal to the input, like the magnet floating on a super cooled super conductor.

I see Igor is using a single cell battery voltage of 1.3v.  That is key to what he is doing. If the input is higher, then there is a chance that the voltage potential developed by the coil collapse could be high enough to breach the gap in the read switch(spark). Reeds are pretty good at fast switching mechanically. Quick to close and open the distance between contacts. So the quicker the reed springs to its fully open position, the less chance of the collapse current from jumping the contacts.

On can easily get higher than input voltages from a coil collapse into a cap using a diode, WITH THE DIODE IN EITHER DIRECTION.      In one direction, when the reed is closed sending power to the coil, the diode does not conduct until the coil collapse. With the diode in the other direction, source current does flow to the cap and coil, but when the coil collapses, the cap gets just about as much HV as it did with the diode the traditional way.  This was when I discovered that the collapse can develop currents in either direction, depending on a way out for those currents. If there is no way out, then the collapse currents will die off within the coil in the form of oscillation within the coils LC. This isolated oscillation within the coil is at its resonant freq, whether it be 4mhz or 100hz depending on the coil and its self capacitance.


Possibly this is what Tesla switching is all about. Using a high speed rotor, the closing of the contacts, then the opening and creating distance very quickly and collapse currents dont have a chance to breach the gap. Just thoughts.

"The inductor changes the directions of electrons, the capacitor does not. Lets say the capacitor has just given all its energy to the inductor and it is the positive peck. Now the inductor has the energy and now the magnetic field starts to collapse, the electrons change in direction, but the potential is still positive for awhile but it is going negative.

The gentleman that makes those clips is very smart and really knows his electronics.  It's wonderful to see how he restores old radios.  So it's strange how in that clip he makes a very basic fundamental mistake.  He says when the capacitor in the LC tank circuit has discharged all its energy then all of the energy is in the inductor.  Then he says the inductor's magnetic field starts to collapse and the current changes direction.

The reality is that when the capacitor is fully discharged and the inductor is fully charged, yes the inductor starts to discharge, but the current does not reverse direction at this point.  The point in time where the capacitor is fully discharged is the point where the current flow though the inductor is at a maximum.  As the inductor starts to discharge the current flow keeps going in the same direction but the capacitor voltage changes direction.

It was just one of those funny moments where he made a mistake, but all in all the guy is great.
