MEMM

@All

I think the following may help those interested in the MEG, related devices, and further research. I know, I know ... spending too much time on documenting, but this is my only hope of defense if I were to suddenly pass on; i.e., if that happened then hopefully the disinformationist would not succeed in convincing people MCE energy is not real or worth much. Please never give up on the MEG. The pulse timing is vitally important!  The amount of load resistance relative to number of secondary turns is vitally important. It would help if the load resistor appropriately changed during the received pulsed, hence it might be worth duplicating Naudin's conditioned resistors. Just make sure you use a common small R (as Naudin did) as a way of measuring the current. IMHO the input power to core is important. That is a lot of combinations. If you change the R 40 times, adjust for 40 different frequencies, and then 40 different input voltages that's 40 * 40 * 40 = 64000 combinations. Please do not give up on the MEG. Finding the exact correct situation for your particular setup could be akin to finding a gold mine, but it will be worth it. Experiment.

First, we know avalanche radiation exists. I prefer to call it "avalanche radiation" over Barkhausen because it's more descriptive and there's a little controversy about Barkhausen, but that's another subject. Point being, we know about the avalanches. We know it is typically UHF radiation for non-electrical cores and considerably lower for conductive cores such as iron. The amount of such radiation that escapes the core is very small. The reason it is small is because the avalanche occurs completely incased within the core and we know the fields have a closed loop, a magnetic short if you will. This easily demonstrated with FEMM. Also we may study induction simulations to learn that core radiation leakage is relative to the materials permeability.

Now to the point. At any given time while we are pulsing a core there are X amount of avalanches occurring that are unstoppable; i.e., if we remove the applied field the avalanches would complete. I refer to this as "Magnetic Momentum" (that's momentum, not moment), and not to be confused with Magnetic Viscosity.

The amount of magnetic momentum varies with material. There are a lot of factors, but the main factors are the materials MCE and its electrical conductivity. I predict that nanocrystalline materials such as Metglas and Finemet have high magnetic momentum.

I would like to differentiate the different between MCE energy and common induction. Envision thousands of tiny PM's (permanent magnets) on swivels that forms one big toroid. There is wire that wraps this big toroid to form a standard toroid coil. Basically we have formed a large scale magnetic toroid core with a coil. These tiny magnets are all aligned to form a closed loop-- essentially our core is saturated. Now at a constant rate randomly force say 100 PM's per second to flip. This will induce a net constant voltage. We know that the net constant voltage is not dependant on how fast _each_ PM flips. Rather the net constant voltage depends on _how many_ PM's _per second_ are flipped. So, the induction is relative to how many flipped PM's per second and MCE energy is relative to how fast a PM is flipped.

In other words, if each PM is flipped in 1 ms rather than 10 ms the net constant induced voltage will not change, but there will be more radiation energy. MCE is that radiation energy.

Note that each time a PM is flipped we'll see a dc pulse (a dc spike) in voltage. If the PM flips 1000 times fast, then the _net average_ voltage does not change; i.e., the voltage is 1000 times greater, but the pulse width is 1000 times shorter. So it flips 1000 times faster. The voltage will be 1000 times greater. If the voltage is 1000 times greater then power is 1000000 times greater-- P=V^2/R. Therefore, power is 1000000 times greater, the time is 1000 times less, the resulting energy is 1000 times greater. Energy = time * Voltage^2 / Resistance. If we were to look at this signal on a spectrum we would see that by increasing the flip 1000 times faster results in higher frequencies. If you flipped it fast enough you would have a high-energy gamma photon, and you better duck. ;-)  E=hf

Hi Paul,
I don't quite understand where the excess energy is coming from.
Is it the change in temperature of the material (MCE) during the input pulse that alters (increases) the stored magnetic energy for when the pulse is removed and picked up by the output coil?

PSU has arrived, core due on Monday, schematic finished, doing track layout now, parts to order over the weekend.

It can output 32v at 2.9A so more than enough for the MEG:

Hi kingrs,

Hi Paul,
I don't quite understand where the excess energy is coming from.

It comes from ambient temperature. Have you ever tried to pull apart two PM's? It takes energy just as it takes energy for the vibrating atoms to break the alignment of the electron magnetic moments.

It's really simple. When the magnetic moments align we get energy-- MCE radiation. That's basic physics. If your pulse is fast enough then all the avalanches (MCE energy) is a coherent pulse. The avalanches give energy to eddy currents-- magnetic momentum. Note that eddy currents is not required for magnetic momentum. Magnetic momentum consists of the avalanches that have reached a stage where it cannot be stopped. At the correct timing you need your resistor load to gain as much energy as possible from that magnetic momentum. If you read my previous post you'll see the difference between induction and MCE energy.

That's great. Remember though, more does not always equal better. Try a wide range of power input levels. See my previous post and you'll see it could take some time, roughly 64000 different variations.

Are you going to replicate Naudin's conditioned load resistors?

Hi Paul,

Thank you for the explanation, its nice to see there is a new refridgeration technology emergy using MCE.

Looking at JLN's scope shots he appears to be using 24KHz as the input signal, yet if you check his circuit diagram with spec. sheet for the TL494CN, his pulse circuit should start at around 40KHz and end at 100KHz.
Therefore I suspect the timing capacitor C1 may be a larger value like 5nF.
It would make sense to put a rotary switch in here to allow a range of values to enable a large number of frequencies to be covered, from say 1KHz to 100KHz.

Hi kingrs,

That would be a smart thing to do. Truthfully, I think Naudin was all over the place, spent a great deal of time on his MEG, varying all the parameters. I wish he posted scope shots of all variations of input voltages, frequencies, etc.

Do you plan on documenting and taking lots of scope shots?  Also I think it's a good idea to eventually try and replicate Naudin's conditioned 100K load resister.
