Magnet coil cores, demagnetization power and Lenz delay.

You also need to remove the coil altogether,and then do another RPM reading. I think you will find that the RPM will also go up without the coil and core there at all.

Right, very good point! Everyone knows how important positioning a power coil precisely is and the large difference a small correction can make. After the power coil's positioned, rotor acceleration depends on the amount of power delivered to the coil. A shorted output coil has no way to vary any power to itself, but pushing it in more closely towards the magnet rotor has the same effect as adding power to a drive coil.

Hob Nire has all his coils positioned at the same distance from his magnet rotor. What happens to the rotor speed when he shorts a second output coil? Nothing! The reason is the maximum propulsion strength has already been achieved by the first coil at that distance. Imagine the output coils staggered in distance from the rotor like a Pan Flute. First we short the furthest, we achieve a few hundred RPM'S in acceleration; Then we short the next closest coil. What can we expect from that one? Additional accelration! The point is we have nothing to gain from multiple shorted coils.

All Hob Nire's output coils in faned sequence would only work as well as one shorted coil on an adjustable worm gear.

I'm returning after a brief diversion to Gotoluc's "Lenz Delay Thread". Milehigh has falsely tutored a group of contributors including Tinman, MarkE, Farmhand, etc. They all parrot MH's "No Lenz Delay" non-theory based on imaginary instrument error and other kinds of stupid arguements. Luc has clearly demomstrated the validity of the theory with his most recent test. Luc's output coil is not shorted, but wired to a high value resistive load. This proves the effect is dependent on a heavy load or a dead short acting as an infinate load or an infinite capacitor.

Luc's ferrite core extends past the Wall of his output, and passes through the entire bore hole. A magnet wave is produced at the tip of the core by the passing magnet pole that travels through the ferrite with a Barkhausen effect resembling falling dominos as the magnetic domains flip in groups. When this wave reaches the shorted coil, it's reflected back towards the spinning rotor magnet. The reflected wave is either lagging or in advance of TDC causing either drag or propulsión depending on the distance the shorted coil is from the end of the ferrite core. The conditions require that a mínimum threshold RPM be achieved by the rotor, and the the coil impedence match the rotor field strength. A slow rotor or weak coil won't get the "Lenz Reversal Effect".

I discovered that after the initial speed up, that the new RPM changes the core viscosity slightly, and causes the refleted wave to lag enough to stall the acceleration. Gotoluc can't test for this repositioing effect because his Dremel driver is already at top speed. The important point I make is that the acceleration advances in "Barkhausen Leaps" not linearly when the new wave reflection position of the shorted coil is reached!

There is no such thing as a "Lenz delay".    "Lenz delay" is an invented term used by some to describe current that is out of phase with the inducing current.   Reactive networks and/or transmission delay mechanisms can store and return energy.  On a cycle by cycle basis the amount of returned energy is never quite equal nor greater than the energy imparted.  That means that one can enjoy all kinds of entertainment by "releasing the (induced current) brake" in an electrodynamic machine by introducing reactive elements and or a transmission delay network that reflects at the far end.  One can readily demonstrate by manipulating such networks that loading on the source  can be reduced.  It can never be reduced to zero or set-up for a gain.  As the load goes to zero so to goes the energy that can perform useful work on or through the load.

@MarkE,

"Lenz Delay Effect" as proved by Gotoluc involves the reflection of a "Magnet Wave" in a ferrite ore and is a "Core Effect"! I know you guys are too busy uploading comments all the time to do any meaningfull research on your own, and it would be too much trouble to ask you to  study JLN'S video series on the effect.
