Interesting experiment with an transformer, 2 lamps, diodes and an magnet

here is video 2

Here is video 1 fromMarkus, converted to a smaller MPEG4- Microsoft V2 codec
which is more compatiblewith older systems and also 1/4 the size.
As there was no speech on the audio, I deleted the  audio part as it contained
only noise...

Stefan, thank you for converting the video.

Better Markus next timeyou speak to the video, what you are doing..

Yes, you'r right. But hmmm, I have to train my rusty spoken English first ;-)
What you see in the video is the procedure I descibed in my first post.

Sefan, I would hear gladly your opinion, now after you saw the video.  Is it only change of the impedance of the core or another effect?
Remark: If I use a lamp instead of the digital multimeter for measuring the ampere consumption from battery, then I can see the consumption drops (lamp becomes darker). Even if the values shown by the DMM are wrong, the tendency is right (decreasing consumption, but at the same time a brighter kickback-lamp).

Thank you for your estimation.

PS: In the video: the upper lamp is the kickback powerd lamp, the lamp at the bottom of the screen is the normal powerd lamp (see diagram in my pictures)

Hi Markus,
please draw the circuit diagramm and post it here.
Otherwise it is hard to say, what is going on there.
Looks interesting, but could be impedance matching or different
BH-working point.
Depends on the used circuit !

Please post it.
Thanks.

Regards, Stefan.

Folks,

Info missing about what type of iron-core is used in this experiment. There are hunderts of different types. Was it used
in dc-to-dc-step-up(down) converter ( 35 Khz-Range ) ?
You need a oszilloskope otherwise you waste your time ( and ours although.

Kator,

I got this core(s) from ebay. But unfortunately without any data about it.
A private person sold some of this cores. It looks like ferrite, but who knows it for sure...?

Sorry, so I can't give you any informations about the core (except the dimensions of the core)

btw: I repeated the experiement with a similar core but not with 42 turns of tesla wire on each side but with ca. 100 turns. And the effect was less significant with this coil.

The next days I post the exact circuit diagram... not today, it was a hard, long day. :-/
And if I get back my other multimeter from repair, I can give you exact informations about the frequency at least.

And yes, I know that I need an oscilloscope. :-)  But I have to earn some extra money first. :-(
(any suggestions for a special exemplar?)

Regards, Markus
