Audio spectrum amplifier.

I'm setting up to power the 1.81 Henry inductor with a "Sinusoidal Audio Spectrum" generator and blue tooth amplifier. The coil electrodes connect to the two wires from the earphone adaptor. 1 to 20,154 Hertz.

Here's an excellent free online tone generator:

I fried my $1200 Mac laptop feeding audio into the powerful two disc neo 1.81 Henry electromagnet at too close a distance. I don't feel too bright right now.

The 1.81 Henry coil needs a 7 Pico farad capacitor to resonate at a sine wave audio frequency of around 500 Hertz. The idea is to reinforce the LC resonance with the audio input and oscillate the magnet field to generate power out. I need to recover my hardware before I can try this.

Sorry to hear about the computer. :-\
If it's any consolation, I don't know any experimenter that hasn't accidentally blown some equipment up in the process.  My first few years learning about these systems probably generated more smoke than power.


Good work with your experiments.  I have a few of the same electromagnets but have not had nearly the amount of success.

@Reiuki,

The screen blacked out. I'm shopping for an external VGI display adapter. Describe to me what you're up to, maybe I can help out. Do you have a spring pressure SPDT switch like the one I showed earlier in this thread?

All of my testing now runs around the Kunel patent (efficient magnetic flux breaking+reconnection) and parametric variation of inductance (Eric Dollard's verser algebra). ;D

I started with a close analogue to your setup, trying a few different spring-switches in mechanical-vibration mode and rectified smoothed output.  3 types of electromagnets, Neo and Ceramic mags, various spacings, voltages, and spring-constants.  But the efficiencies I was getting out of the setup were still not great.  I suspected switching speeds were playing a part, so my follow-up experiments have almost entirely been solid-state (audio amp driven and DC impulse driven).  My tests are linearly more efficient with higher-voltage impulses, so I am carefully working my way up to delivering much higher voltage impulses safely (IE: without smoking the MOSFETs).


As for your equipment, I'm guessing the ~300v backlight LCD inverter board/power supply for the monitor is what blew?  Not sure about fixability, but at least it wasn't a total HDD burnout.  Maybe you'll get lucky and it's a (relatively) cheap single-board swapout :) .

I 'm connected to an external monitor and running my audio tone generator again with my resurrected Macintosh. This program will not work with the Windows operating system.

Ideally, a variable capacitor, or pico farad trimmer cap should be connected to the inductor of the LC tank. An amplifier needs to be connected between the tone generator and the inductor to raise and lower the amplitude. The tone generator generates voltage.

Wootan and McClain determined that the resonant frequency of magnetism "ferromagnetic resonant freq is 174.8KHz" with their Piezo driven MRA. Penciling in the arithmetic and tuning the LC circuit to match the tone generator and amplitude are an art not a science. The audio frequency has to be an octave fractal, because it only rises to 20Khz.

174.8 kHz divided by 13 equals 13.44; The capacitance for 13.44 kHz with 1.81 Henrys is  77.475  Microfarad.

That means attaching a 77.475 Microfarad capacitor would generate an LC resonance that would ring at 13.44 kHz of audio frequency input and be a 1/13th fractal of ferro-magnetic resonance. This is where I plan to start.

I purchased a 6 watt amplifier at Radio Shack and can generate an awesome vibration with my online audio tone generator. I also turned my 1.81 inductor around so the magnetic "E" core is facing the magnets.

I performed two tests during the course of this thread that I believe are important. First I measured negative inductance with my DMM on a coil with a ferrite core reduced to zero Henrys by extending the ferrite core, and registering in the negative range while a magnetic field was induced in the coil by the penetrating core.


The second, was the demonstration that a stack of magnets suspended by one electromagnet coil by magnets attached to the top, will generate an equal amount of power in the coil when the attraction strength re couples the magnets, and this power is generated in the EM coil that generated the disconnection pulse. This exchange is equal to infinity!

The attraction force oscillator I demonstrated with the SPDT spring pressure switch returned all the power of the interruption pulse: The input and output are transformed from low volt pulsed D.C. to higher voltage A.C., so it acts as a 100% efficient transformer inverter. Voila!

My attraction neutralization oscillator caloric measurements have opened a new amplification approach that multiplies the oscillator COP by thousands of times:

MCE, or "Mageto-Caloric effect": The presence of the external permanent magnet field raises the temperature of  the cobalt alloy  electromagnet core, and the neutralization pulse cools it.


The currie point of Gadolinium is 20 degrees centigrade. This is close to room temperature.


An Attraction Neutralization oscillator with a Gadolinium core would increase the field differential thousands of times. The EM power pulse would neutralize the powerful external field, cool the gadolinum core and cause it to grow magnetic. When the external field reappeared, the core would reheat, loose it's attraction strength and release the magnetic piston. 


The output would be equal to the electrical power it would take to generate the field strength to match the magnetic attraction of the gadolinium core. This would all be "Free Power".

Here's a very simple design for an over unity MCE solid state generator:

An axial polarized neodymium cylinder wrapped with a copper coil and connected to a power source so the two fields reinforce each other; Placed in adjacency to a "Gadolinium Cylinder" would generate power when pulsed under the following conditions:

The ambient temperature is close to the Currie point of 20 degrees centigrade. The combined field strength of the Neo magnet and coil is sufficient to raise the temperature of the "Gadolinium Cylinder" above the Currie point so it relinquishes it's magnetic attraction. Upon de-energizing the magnet coil, the temperature of the "Gadolinium" would drop, the attraction strength would return and the permanent magnet field would be drawn toward it through the coil wraps generating a current therein.

Here's a terrarium temperature control setup for $30 dollars off Amazon that uses an electric fan and electric heater to control temperature down to 1/10 of a degree centigrade. Plenty of tolerance to house a very powerful solid state currie point MCE generator:

A neo horseshoe magnet with complimentary coil and a gadolinium stator linking the poles would open and close the magnetic flux gate inside the climate control zone.


We need an SPDT switch to run it. Energizing the coil would raise the temperature of the stator above the Currie point and close the flux path. De-energizing the horseshoe magnet coil would lower the temperature of the gadolinium stator, and open the flux path between the horseshoe poles, generating output from within it's own magnet coil, directing the output to the destination through the SPDT switch. No moving parts.


The climate control unit would be portable and fit in a car trunk or VTOL cargo hatch.

Here's a 3/4" diameter gadolinium coin and a schematic of the Flynn multiplication of force concept:

Two Horseshoe magnets connected through two gadolinium coins would produce the phantom force of a third magnet when the flux gates are open.
