Linden Experiment

[frankl]

I'm an armchair dabbler with an interest in the Testatika. I'm wondering if any of you folks have attempted to replicate the "Linden Experiment" with the U-shaped magnet and two-metal capacitor.

I managed to obtain (after a lot of searching) some large steel u-shaped magnets and have started doing a few tests.
Wrapping house wire round the magnet about 15-20 times and joining the two ends together, I got a clear dip on the dip meter at around 70 mhz, then two harmonics at 140 and 210. Changing the length of the wire or number of turns did not appear to affect the resonant frequency.

I did attempt to create the capacitor but it didn't produce any voltage (I think I need plexiglas instead of the bit of plastic packaging I used)
My primitive observations are:
1. Its like a magnetic tuning fork producing standing waves, I suspect the frequency will change according to the size of the magnet used
2. I think the distance between the plates (i.e. thickness of the plexiglas) may need to be an accurate fraction of the gap between the legs of the magnet. Having looked at various photos of the machine there always seems to be the same number of plates packed between the legs of the magnet.
3. Somehow it is causing the metals to emit electrons but not in equal amounts (due to some quantum thing) causing a potential difference.

sorry that was misinformation - the frequencies increase with less turns and vary in separation between the harmonics.

Haven't tried changing the length of the free loop to see if that makes any difference.

It seems like their might be a point somewhere between about 20 and 25 turns where the 1st, 2nd and 3rd harmonics are in correct proportion with each other. (i.e. a, a*2, a*3)
Like you're tuning it so both legs are singing the same tune

Hi Frank,
This is a very interesting test. My guess is that the loop is a lecher line
as in the picture I've attached. Changing the length of the free
loop, and possibly the orientation, would also have an affect on
the frequency. It may be easy to do this is you make the loop
as in this picture.

To make it easy to try different lengths you could do something
like in the picture. Have the ends of the coil that's wrapped around the
magnet be connected to two bare conductive rods. The rods are therefore the
lecher line. To close the end of the line/rods and to vary the length,
simply have a bare conductive cross bar, e.g. a bar of copper, and just
sit this on and move it along the rods (taking your hand off it each time,
or moving it by using an insulated stick so that your body's voltage won't
interfere.) For the spacing between the rods, just make it so you can move
them closer or farther appart. If all the entire setup is sitting on a
piece of wood then you can just rotate the wood for different
orientations. The overall experiment would be tedious due to all the
permutations to try. Start with a Earth magnetic north-south first though,
just in case that's the proper orientation. Just keep your volt meter
attached to the capacitor between the legs of the magnet as you vary
things. You might all of a sudden see a spike!

Possibly what Paul Baunmann realized from this simple experiment is
that if you ran the right frequency through the coil around the magnet
then a voltage would be induced in the capacitor between the legs of
the magnet. The use of the lecher line was how he gathered the energy
and set the frequency with this experiment. With the other machines
he used other means (since there's no lecher line in them.)

Thanks for the reply Steve

I was testing with a fairly long loop last night and I noticed a change of about 2mhz just moving the loop round about 120 degrees.
It doesn't seem to matter too much though if the loop is in a big circle or tight together like the lechter wires.

2 rods and a bar seems like an excellent suggestion for tuning it, I'll see what I can rustle up for that.

I still need a better capacitor- I'm now using copper and aluminium foil both about 1/2 mm thick. Can't get plexiglas anywhere so I was thinking of making a thicker plate using resin. Maybe that's what Baumann used to make everything fit so neatly between the legs of the magnet.

I'll put some photos up once I get a better set up.
