Confirming the Delayed Lenz Effect

[conradelektro]

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.
..........
All the best, DC.

In option 3 I forgot to mention the Adams or Bedini circuit, which was of course the starting point for the circuit I showed.

I like a separate trigger coil (in contrast to winding the trigger coil onto a drive coil) because the separate trigger coil can be placed at a sweet spot. One can place it at a certain distance from the passing magnet(s) and also slightly offset from the theoretically demanded position to influence the moment it triggers the transistor (driving the drive coil or coils).

I have seen ball magnets driven by the Bedini circuit (or a close variant of it), but I wonder why it works. Only one magnet pole should trigger the drive coil in the correct way. What happens when the other magnet pole passes the trigger/drive coil is a riddle to me?

I attach a drawing depicting the "drive problem" when using a Bedini style drive circuit and N S N S facing magnets on a rotor.

But as I said, it seems to work with a single ball magnet and a single diametrically magnetised ring or tube magnet. But I doubt a Bedini style circuit will work with a rotor having magnets along its circumference with alternating poles N S N S.

I will make some tests, but it has to wait a few weeks.

Yes, i'm familiar with the problem.

When i use an inductive drive coil on a N/S rotor it works but only at just over half the speed of the same rotor with the magnets turned N/N.

I'm also surprised there is any rotation, perhaps the flywheel effect is to account for it, the mass/velocity of the rotor overcomes the opposing pole ?


All the best,

DC.

Hi synchro1, DeepCut and everyone,

Looks like much activity has been going on here.
I was away for a few days driving from Florida back to Canada.

I just now ordered 2 Diametric cylinder Neo magnets: http://www.ebay.com/itm/120743166252?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649  to confirm synchro1's findings. However, now that I'm in Canada the delivery will take some time since the magnets come from the US. If I was still there, I would of received them in 2 to 3 days.

Looking forward to testing synchro1's findings

Thank you for sharing

Luc

Hi Luc, must be nice to be home again

My acrylic tube has arrived so i will be testing a magnet as a core as well.

Sync says that the generator magnet must be spun up to full speed in order to negate it's attraction to the core magnet, i do this using a typical Adams/Bedini drive coil.

With a very light shaft (carbon fibre) and miniature, flanged bearings, my magnet spins at up to 40,000RPM with an input of around 7-8 watts.

Looking forward to sharing results/observations,

DC.
