Confirming the Delayed Lenz Effect

[hoptoad]

The bearings are very expensive. Here's the website for them. This build looks simple, but attaching the bearings requires patience and craftmanship. I'll help guide you through it. The bearings are absloutly essential to getting the OU results! There's nothing to the output coil. Just a Radio Shack magnet wire spool, wraped full bifilar with green wire, and two 1/2" dametric neo tubes fit snug in the hollow 1/2" core.

Cheers, its nice to try something different. I have seen similar builds to yours, but not with the diamagnetic rotor and diamagnetic inserts inside the output coil. Sourcing a few things will take me a little time (I'm slow - LOL) , but I'll make the effort and investigate the configuration you've explained.

One thing I'd like to mention. When direct switching with reed switches, use analogue meters to take run time measurements, if possible, not digital meters.  Analogue meters aren't affected by RF interference.

Before, and after run measurements, with DSO's are fine, but the actual sparks produced in the reed switch during run time produce high frequency radio waves that play havoc with most DSM's and DSO's sampling / accuracy.

Whew, they are expensive! I'll have to get my wife to shop the net for me. She can hunt down a bargain like a hound after a fox!
Thanks again for the info. The most appealing thing about your setup is that it complies with the K.I.S.S. principle.

If you go to kjmagnetics.com and type diametric in the search box, unfortunately the results page is also full of axially magnetised magnets but just search within the results page (CTRL+F) to find diametric ones like this :

Let's discuss drive circuits. Somehow the rotor has to be driven, then one can try various Tesla style pancake coils or "coils with a diametrically magnetised core à la synchro1" for energy harvesting (hopefully without the Lenz effect):

1) The most simple way is to drive a rotor (having the N S N S magnets for energy generation) with a separate motor, e.g. a DC motor. Jean Louis Naudin uses a brushless motor with a special drive circuit http://jnaudin.free.fr/dlenz/DLE07.htm .

2) An other simple way is to use a reed switch to turn on and off one or several drive coils. It has been suggested by synchro1 to use a "bifilar series solenoid style drive coil". I do not like reed switches because they are not good for high frequency switching and do not last long.

3) I tend towards a drive circuit (driving one or several drive coils) based on a transistor and a sensor coil. Both drive coil and sensor coil could be "bifilar series solenoid style". See my Reply #717 at http://www.overunity.com/11350/confirming-the-delayed-lenz-effect/705/#.UU2YpFfovbE. It is not clear whether that circuit will work with N S N S magnets on the rotor.

4) One could use a hall sensor and a transistor to drive the rotor with a drive coil. Again it is not clear how to do that with  N S N S magnets on a rotor.

May be experimenters could publish their drive circuits and arrangements.

@DeepCut: how do you drive the rotor (one magnet spinner) in this video https://www.youtube.com/watch?v=dj9GJ-BlfiM ? May be you have no objection to publish the circuit (schematics and component specifications).

I use your option 3 in that setup.

It's the basic inductor circuit used by Adams then Bedini, the sensor or trigger wire is on the same coil-former as the driving/pulsing wire.

Mine isn't particularly efficient, using 7-8 watts to drive that very light, single-magnet rotor, but the rotor can get up to 40,000 RPM depending on the choice of resistor and has generated in excess of 1 kilovolt at 3 or 4 mA in an inductor made of two pounds of wire.

For heavier rotors i use a high quality DC motor from an Audi A8 pump massage system.


All the best,

DC.
