New youtube of magnet/coil "perpetual motion"

Hi broli,

yes but he says at around 2:11 - 2:12 that the other part of the electric valve (i.e. a transistor) opens up the big coil (after the small coil got maximum induction and switched the transistor on....)  hmmm   English is my second language but is it not what he said?   

So the input part of the "valve" must be the base-emitter or gate-source of a bipolar or a FET transistor and the output part must be the collector - emitter or drain - source part.  There must be something else (i.e. component) involved. 
Could you listen to it again?

Hmm,
maybe he is using the shorted outBackEMF of the larger coil to repell the magnet ?

Hi Stefan,

very briefly, how would it work then?


Other thing I forgot:  we should consider the effect of iron core in the big coil. 
(it seems the small coil has no core but mainly the big coil has, standing out at its backside)

EDIT:  the small coil also has the core but the core is a little bit pulled backwards in it.

The high impedance coil gets shorted by the transistor at just the right time. You need high impedance coil to minimise switching losses in the transistor or FET.

This coil short causes the core to produce overall asymetric (about vertical B axis) BH curve during one complete core mag interatction and so a  net force is developed. When you short a coil that coil will act as a flux guide, and will cause the core to be pushed closer to saturation, I think It is similar to whats going on in @crankypants perepetia effect. Most of the Lenz effect is there as usual. But the new effect causes the core to attract the mag just a tiny bit less on the way out. The core will probably cool down slightly if insulated well.

It´s also the same thing that Steorn are trying to capitalise on, their new orbo has a coil, core and mags and probably uses an emebedded low Rds FET mounted on a high impedance coil.

Hmmm. I wonder if a ready wound 240V coil from a fishtank vibropump could have a trigger winding piggy backed on it to trigger a FET? Even if it won´t run a wheel it may give a slower wind down time which would prove something special is going on.

May I suggest looking at this person's work... http://home.earthlink.net/~lenyr/magkick.htm

Yes, it uses a battery but use some imagination. Replace the battery with a pickup coil.
