These are attempts to replicate the Linden Experiment and figure out if the horseshoe magnets used in the testatika in general are tapping an energy source. All these experiments involve the use of my POS400+ UHF chip oscillator circuit to do pulsing of the magnetic field. The dates given are approximate as sometimes they were done over multiple days.

Dec 6, 2007 - Linden experiment with meter magnet driven by POS400+ oscillator

First I tried the Linden experiment but using the POS400+ oscillator to pulse the magnet. I adjusted the control voltage in steps of 0.1 volt from 4.0 volts to 12.0 volts. As the graph at the bottom of my lecher line tests show this is from around 280MHz to 425MHz. The magnet was lined up with it's south pole on the geomagnetic north side and the north pole on the geomagnetic south side.

As previously discovered during my first series of Linden experiment tests holding the capacitor with the fingers of one hand put a voltage of 1.5 volts across the capacitor. At no time was any additional voltage seen.

Putting the capacitor in place between the poles.

Applying the voltage test probes.

I also checked for induction to find the control voltage that gave the most induction by putting a UHF diode, NTE503, between the probes of my multimeter and looking for when the voltage on the multimeter would be highest. Highest induction turned out at a control voltage of around 4.2 volts, corresponding to around 297MHz.

The diode.

Testing for induction. This gave around 0.25V on the multimeter.

Testing for voltage. Touching one leg of the diode in this area on the magnet gave an induced voltage of around 0.42V. Comparable voltage was found in other locations too.

Dec 9, 2007 - Horseshoe magnet with DC voltage on plates between legs

I next tried a 4" tall horseshoe magnet with a DC voltage applied between the legs. See the photos below. 0VDC to 30VDC was applied to the plates sandwiched between the legs and pressing against the coils wrapped around the legs. The coil around the top of the magnet was pulsed by the POS400+ oscillator. Tests were made with the bottom ends of the leg coils in electrical contact with the magnets and without. The result was hoped to be a voltage across the coils wrapped around the legs. No such voltage was seen.

Dec 16, 2007 - Meter magnet with plates touching poles to variable capacitor

I next tried making a more complete electrical contact with the poles of the meter magnet by pressing two plates against them, using plasticine to hold them in place as the following photos show.

I then looked for the control voltage where there was the greatest induction, this turned out to be around 333MHz. I calculated the inductance of the coil wrapped around the magnet to be around 9.072mH which meant the inductive reactance would be 1.898x10^-7ohms. Assuming the same for capacitive reactance, I calculated a resonant capacitance of 251.8pF. I next calculated the required plate area assuming a paper dielectric, coming up with around 27.2square centimeters. I arranged such a capacitor and repeated the Linden experiment at around 333MHz both with my fingers touching the capacitor plates and without. No result.

Dec 20, 2007 - Meter magnet with partial oscillator electrical contact giving better results.

Through playing around I found that I got more inductance by electrically connecting from the oscillator to the meter magnet by placing the magnet on the DC connection and leaving the ground connection separated, as in the photo below.

So I connected the diode in series with the voltmeter probes and measured this way across the plates that were in contact with the magnet's poles. I also connected an ammeter in series too. The following photo shows this. The result was 1 volt at 10microamps DC. Nothing to write home about, but the best up to this point.

I then put the plate capacitor I'd made for the December 16 tests such that voltage would be accumulated on it and measured across it. The best I got was with a control voltage of around 4.0V giving around 1.2V on the meter.

Dec 21, 2007 - Pulsing the horseshoe magnet from the plates between the legs.

It always puzzled me why the dual disk small machine had nothing between its horseshoe magnet legs but had coils with around 8 to 10 windings wrapped around the tops of the horseshoes whereas the 3kW machine's horseshoe magnets had no coils wrapped around the top but did have something between the legs. It was obvious that the dual disk small machine's magnets were being pulsed Linden-experiment-style with a coil but there was no obvious way that the 3kW machine's magnets were being pulsed. From previous experiments I knew that flat plates act as good EM antennas around these types of machines, so I realized that maybe the plates between the legs were acting as antennas and as a result, pulsing the magnets. So... as the following photo shows, I hooked up the oscillator to the plates sandwiched between the legs of the 4" horseshoe magnet.

The remainder of the test circuit consisted of measuring the voltage coming out of the coils wrapped around the legs with a diode in series. Charge was accumulated on the plate capacitor. I tried with the bottom ends of the coils in electrical contact with the magnet and without.

Current was at the very lowest measurable, 1 microamp. No voltage was measured when the bottom ends of the coil were not in electrical contact with the magnets. Results were found with different control voltages when the bottom ends of the coils were in electrical contact with the magnets:

Control voltage	Approx. frequency	Coil voltage
0.059VDC	200MHz	120mVDC
6.0VDC	315MHz	100mVDC
9.5 to 10VDC	370MHz	80mVDC

All other control voltages between the above ones gave 0 coil voltage, so some form of resonance was happening. Note that the best was at the lowest control voltage I could give, meaning that possibly lower frequencies could be found that would be even better. I put the digital multimeter in place of the analog one and measured 153mV. Voltage across just the diode was 73mV.

Without the diode there was no DC voltage and no DC current.
