Confirming the Delayed Lenz Effect

[gotoluc]

Hi everyone,

I will give an update on my tests a la Synchro, using 2 diametric 1/2" x 1" Neo magnets.

One magnet is attached to the prime mover which can turn it from 10k rpm to 35k rpm and the other magnet is used as core of a bi-filar series connected coil.

I played with this arrangement for over 3 hours and have not found anything unusual.

So Synchro, if you feel both DeepCut and I are doing something wrong!  then you need to do a well documented video to demonstrate this speed up effect you're talking about.

@Gotoluc,

I described a pair of diametric magnets coupled end to end, for the coil core! The spinner should be a larger diametric tube. That's a minimum total of 3 tube magnets. My cores were 1/2 inch in diameter (2 end to end), with a 3/4 inch spinner.

The coupled diametric's focus the combined feild away from the ends, and towards the center of the output coil where it acts as a speed bump for the pole shift. It's very important to pay attention to my instructions! Deepcut just got through making the same mistake!

It takes two coupled magnets to block the shift. The field knits into a knot in the center.

I just want to correct myself for this statement:

If you see people using coils like this in video clips driving LEDs, all that means is that the self cancellation is not perfect, and the coil still possesses a small amount of inductance and it can act like a very weak pick-up coil.

Suppose you have a 100-turn clockwise pancake coil.  On top of that you have a 98-turn counter-clockwise pancake coil that is slightly smaller.  So there are two "free" turns on the clockwise pancake coil with no "matching" counter-clockwise turns to cancel them out.

There is a very good chance a coil with this configuration will drive an LED load just as brightly as a regular pancake coil.  That's because all of the magnetic flux of the spinning rotor magnet still passes through the coil, even though it is effectively only two turns.  So experimenters should take note of this.

It's not the number of turns that determines how much power you can pick up from the passing rotor magnet, it's how much of the flux you "catch" going through the "loop" that counts.  The extra turns in the pick-up coil can give you more voltage but the trade-off is less current for the same output power.

What this also means is that a coil with a smaller diameter will normally catch less flux and therefore have a lower power output.  Just a review of the basics.

Some interesting findings done by Tesla:

"I had discovered, however, that rotation is produced by means of a single coil and core; my explanation of the phenomenon, and leading thought in trying the experiment, being that there must be a true time lag in the magnetization of the core. I remember the pleasure I had when, in the writings of Professor Ayrton, which came later to my hand, I found the idea of the time lag advocated.  Whether there is a true time lag, whether the retardation is due to eddy currents circulating in minute paths, must remain an open question, but the fact is that a coil wound upon an iron core and traversed by an alternating current creates a moving field of force, capable of setting an armature in rotation.  It is of some interest, in conjunction with the historical Arago experiment, to mention that in lag or phase motors I have produced rotation in the opposite direction to the moving field, which means that in that experiment the magnet may not rotate, or may even rotate in the opposite direction to the moving disc.  Here, then, is a motor (diagrammatically illustrated in Fig. 17), comprising a coil and iron core, and a freely movable copper disc in proximity to the latter. To demonstrate a novel and interesting feature, I have, for a reason which I will explain, selected this type of motor. When the ends of the coil are connected to the terminals of an alternator the disc is set in rotation.  But it is not this experiment, now well known, which I desire to perform.  What I wish to show you is that this motor rotates with one single connection between it and the generator; that is to say, one terminal of the motor is connected to one terminal of the generator—in this case the secondary of a high-tension induction coil—the other terminals of motor and generator being insulated in space."

I recommend to read the previous and next paragraphs...Three paragrahs ahead Tesla states the well know quotation: " Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe"

What is happening here??

Today Skycollection published a new youtube video confirming the delayed lenz effect with a pancake coil which did not alter the rotor speed when shorted, and, if connected to a capacitor and a battery could recharge the battery. I could see that video 7 hours ago.

Now I tried to watched again and I have noted that Skycollection has deleted all his videos uploded in the last month including everything about the Zero Lenz Dynamo.
