@MarkE,

Take a close look at this JLN test:

JLN's sliding the coil down an iron core. He gets the "Lenz Delay" at 30mm. My question to you is;
What effect would placing a magnet at the end of the core have on the distance for the DLE effect?
Would it shorten the length increase the length or have no effect on the length?

The explanation is that the experiment does not evaluate what it claims.  When transferring energy or continuous power between a source and a load, the impedance matching of the source and the load determine what percentage of the available power from the source flows to the load.  Under circumstances where there is a large mismatch then the larger impedance of the two dominates.  This is the case for example with the electrical loads in your home connected to the power utility.

By moving the shorted coil around over the iron rod, JLN changes the coupling impedance and efficiency.  What he doesn't do is get is an effect where induction is delayed.  Induction delays development of force in the direction of motion, which is as I previously described, always against the direction of motion and therefore always a braking effect.

This experiment is likened by JLN to some of Thane Heins experiments as well it should.  Thane Heins has done a number of experiments where by biasing magnetic materials he reduces the BEMF / torque constants of various motors.  Driven by a fixed voltage supply and lightly loaded by only bearing friction and windage, the result is to increase the free running speed of those motors while reducing their torque at any current.  The effect is similar to what happens when one winds a motor with fewer turns of wire.

F=MA, Force equals mass times acceleration. When the rotor speeds up the force increases.

Look at JLN's 2sGen. We see magnets, a coil wraped nano perm toroid and an output coil. Look at the output interval compared to the pulse width on the scope shot. It's 7 or 8 times as long. The DPDT relay needs the same ratio of output to pulse lag time to recover all the power from the demagnetization of the magnetite core in the GAP power coil of kEhYo. The demagnetization output is generated on the quanta plane through an atomic reordering process. JLN calculates a COP of 8 x OU from that scope shot. This is simple to achieve by reducing the rotor magnets to 2, and leaving the DPDT relay normally closed to output to the storage for 180 degrees. 

Here's the link to the GAP motor video. kEhYo has a Hall effect sensor and mosfet powering one strand of a bifilar coil, the other strand gathers output from the pole reversal. My design calls for a single wire coil and a DPDT Reed Relay. The relay wires to the battery for the neutralization pulse, then goes normally open to a storage capacitor.

The Reed Relay has eight pins. Two of the pins are for mounting and are inert. The GAP motor would have the two neutralization coils in series, leaving two leads which would solder to the center pins. The battery in series with a potentiometer would attach to the normally open pins on one end, and the storage capacitor in series with a fast switching diode would attach to the normally closed set of pins on the other end. The Reed Relay triggers from one pole and that's the pole you want to face out from the monopole rotor. You can easily test the relay for the closed side with a battery and 12 volt light bulb. Also the trigger pole polarity.

Synchro1 I plotted the V*T area of both the on pulse and the flyback pulse and they match as expected.  Energy only comes out of the coil when the voltage is above the supply (red in the picture).  Energy goes into the coil when the voltage is below the supply (green).  The oscillations represent energy sloshing back and forth between the inductance and parasitic capacitance of the circuit.  The rest of the time the coil is neither taking energy from the power supply nor taking it from the load.  This is acting like an ordinary voltage boost converter.

If you are happy with mechanical contacts that is fine.  Personally, I would wire up transistors in order to close down the timing variability and problems with contact bounce.
I've watched that video before and found nothing out of the ordinary.

As the rotor magnet approaches the output coil, a

changing

magnetic field appears in  

cuts

the coil that opposes the passage of the passing magnet.

induces a  voltage and resulting current that opposes the change in magnetic field that created it.

   Positioning the output coil 30mm down a iron core

results in eddy currents in the rod that do the same thing, and while the eddy currents flow reduce the magnitude of the field that cuts through the coil creating the apparent delay.

delays the formation of the opposing field in the coil. This has nothing to do with current. The delay is in the output field development.

This apparent delay is an ordinary consequence of Faraday induction and Lenz' Law acting on the iron rod.

  The propulsion is a consequence of the field appearing late behind TDC resulting in a shove instead early in opposition causing drag.

This is claimed propulsion that the experiment does not actually demonstrate.

Lenz force can be positive or negative. Reversed it imparts a power pulse while still generating current in the output windings. This results in net gain.

Absolutely not.  Lenz' Law defines the direction of an induced voltage and it defines it in such a way that is consistent with Conservation of Energy.
