Hi Eldarion,
Yes, it seems missing. That Wiki page of mine sure gets nothing but
trouble, lol. I'll try and fix it Monday.
Thanks,
Paul
What happened to your question eldarion? That's strange. Anyhow, if I
did something to delete it then sorry, but not sure how that would
happen. Here's your original question -->
Huh. That's odd. I didn't delete it.
Maybe that's part of the reason for the "Beta" designation from Google?
:-)
I'll look for the changes in the Wiki on Monday.
Thanks!
Eldarion
Hi,
I forgot Monday was Christmas, but I quickly fixed it again. It's now
fivefold. :-)
http://peswiki.com/index.php/Site:MEMM:5
You can now read the fivefold tips, unless it's corrupted again, but
the best bet is completing my computer simulation of magnetic material
on the atomic scale so then I can create a movie and publish it at
google movies. A picture's worth a 1000 words. How many words is a
movie worth? The movie will show the atomic magnetic moments in
action, what is happening, and exactly how the coils gather energy from
ambient temperature by means of magnetic material. This is *not*
advanced technology. It is old science that will *not* lead to weapons
of mass destruction. :-)

Paul
Thank you! I can't wait to see the 1,000,000 word movie ;-)
Merry Chirstmas!

Hi,
Does anyone know of public domain software that can convert many images
(bmps, gifs, or whatever) in to an mpeg?
The computer simulation software is coming along. There's most likely
some remaining bugs, but it's at the point where I could release it for
others to use and even create their own cores to see what happens. So
far the high-speed trick is working and allows much larger magnetic
atomic arrays. Presently it has everything built in, including
temperature, except no wires yet. So I cannot simulate the effect of a
coil. Also I need to allow the atomic moments to move around, which
will result in magnetostriction. Presently the magnetic moments can
only rotate. Another lacking feature, although not required, is the
addition imperfections in the magnetic material. Real magnetic material
is imperfect and contains a great deal of impurities that cause various
effects such as pinning.
Here are some very interesting results, already:
* Took a round toroid at high temperature well above the Curie point
where the atomic moments are violently randomly rotating. Then the
material is rapidly cooled to near absolute zero Kelvin. This is
actually not an instant process and requires appreciably time due to
PME (Potential Magnetic Energy). IOW, all the KE is completely removed
from the atoms, but there still exists PME, so the atoms begin to
rotate. It seems this process cuts the KE by ~~~40%. So with a click of
the mouse all KE is removed, but due to PME the KE rises up to 40% what
it used to be. During a deep freeze process the computer will
constantly removed the KE. This slowly and eventually removes PME. Over
an appreciable time the PME level will be significantly low, in which
case I can turn of the deep freeze mode and the material will remain at
a very low temperature. So far the results are fascinating, as the
rapid cooling process creates imperfect domains even though I have yet
to add impurities to the magnetic material.
* Performed the above experiment except the material was slowly cooled.
This resulted in near perfect larger domains. It is interesting that
Metglas and Finemet are created using an extremely rapid cooling
process. It's also interesting that such nanocrystalline and amorphous
materials have smaller domains, which is what I am seeing in the
simulations.
* With every simulation I have witnessed PME (Potential Magnetic
Energy). One interesting experiment was to watch a nano size toroid
form two domains. The temperature was then quickly increased and then
removed. This was performed about half dozen times, which eventually
resulted in the material snapping into its highest KE (Kinetic Energy)
form, which is one single domain. This single domain formed one loop
around the toroid. IOW, it was a saturated toroid. This entire event
was essentially one magnetic avalanche. There were a few key atoms in
between the two domains preventing the avalanche. It was the
temperature that caused the key atoms to break their magnetic bonds
from each other that caused the avalanche. What's interesting is the
moment just after the key atoms broke free I removed all KE from the
core and watched the avalanche generate tremendous amount of energy.
That is PME in action-- converting PE to KE.
* Waves of energy caused by avalanches sweep around the toroid core.
That is what I've referred to as "ring resonance." The time it requires
for such a wave to traverse one complete circle around the core is the
ring resonance.

I do not know of any open-source software to do this.
If you are unable to find a free piece of software, I have 3ds max 9
which is capable of doing what you want. If you would like, you could
send me the frames and I could send you a movie.

Just wondering how things are going; I haven't heard from you in a
while.
Must be something good to keep you away from the computer so long! :-)

Hi Eldarion,
Actually I'm being held back by a calculus mathematical problem in
trying to introduce the wires in the magnetic simulation program. I
purchased a bunch calculus books from http://www.half.ebay.com in hopes
of find the solution. Has anyone shopped at half.ebay.com? It's really
cool if you want books, movies, or music! It's another ebay site, but
different in that the S&H are fixed. Example, the first soft cover book
cost $3.25 for S&H, but the rest cost $1.65 if you buy from the same
seller. DVD's cost $2.69 for first and $1.65 for the rest from same
seller. Here's some great book deals I've purchased -->
The Electronics Problem Solver by REA, 1300 pages, $2.66 + $1.65 S&H = $4.31
The Calculus Problem Solver by REA, 1100 pages, $3.33 + $3.25 S&H = $6.58
Technical Calculus : Dale Ewen, James E. Trefzger, Joan S. Gary
(Hardcover, 2001), 636 pages, $0.75 + $2.15 S&H = $4.45
Calculus the Easy Way : Douglas Downing, 320 pages, $0.75 + $1.65 S&H =

Crouching Tiger, Hidden Dragon (DVD, 2001), $1.99 + $1.65 S&H = $4.68
One of my favorites is The Calculus Problem Solver by REA. This cost $30
in stores + $2.48 tax. The book "Technical Calculus" costs $147 + tax
new, but amazon has it for $128, but it was just $0.75 + $2.15 S&H. :-)
Anyone who's interested in Quantum Physics without all the heavy
mathematics I recommend "The Odd Quantum" by Sam B. Treiman. It's QM
although it's recommended that you know basic calculus.

Paul Lowrance
I have taken several calculus courses in college; if you would like
some help I would be happy to try my hand at the problem.

Eldarion,
How is your project going?" TinyMEG" have you ran across some issues with it lately? I have not been on very much lately, I was just wondering how you were doing. Is the (CORE AMCC 4) working out, or if you had verified that it would not work for your experiment?I have been thinking of getting a core and starting to work with one, but was not sure on which one to try?

Eldarion,
Glad that you are not abandoning your project, if you get into a situation with the magnets, I may be able to help as I have some places that make the magnets and they may have some in stock that may fit your needs. I am not sure where you are located at Eldarion, but there is a magnet company in Ohio that manufactures magnets, I have some listings of some over seas also on the other PC.
Hang in there, sounds like you are getting closer to getting something going.

Hi Eldarion,
That would be great. I'll write up the problem now and post it.
Thanks,
Paul
Hi Eldarion,
The math problem is about circular motion. Picture a magnetic moment
dipole in space that may only rotate in accordance to an applied
magnetic field. We can refer to the magnetic moment dipole as a PM
(Permanent Magnet). The angular distance would be how far the PM
rotates during one time unit, dt.
Lets set up the problem. At a specific instant in time we have a PM
facing north, which we'll call zero degrees. Also we have an applied
magnetic field on the PM pointing X degrees. Lets say X is 90 degrees
(east). Therefore there is an angular force on the PM to rotate
clockwise so it aligns with the applied field. The equation for the
PM's angular acceleration at any instant in time is -->
a = sin(PM angle - H angle)
a = The PM's angular acceleration.
PM angle = Magnets angular direction.
H angle = Applied fields angular direction.
The issue is that acceleration is not static. If the acceleration were
static then we could use the following common equation to find the
distance the PM travels during one unit of time -->
angular distance = initial angular velocity * dt + 0.5 * angular
acceleration * dt^2
dt = elapsed time
As you can see, the above equation relies on the angular acceleration
being constant during the entire elapsed time period, dt. In my math
problem the angular acceleration changes as angular distance changes,
and is therefore not a constant. We could graph the above common
equation to see what it's doing. The above equation is a common physics
equation based on F = m*a, where F=force, m=mass, a=acceleration. On a
graph the horizontal would be time and vertical would be angular
distance. As time increases, the angular velocity changes by delta
acceleration, which is constant. That's an easy calculus problem since
angular acceleration is constant.
Now lets conceptualize a graph of our problem where acceleration is
dynamic. PM is at 0 degrees and H is at 1 degree. Lets say that during
1/2 a time unit the PM rotates 1 degree. Therefore, the PM is perfectly
aligned with H angle, but we're not finished since we still have another
1/2 time unit left. In real life during the other half of time unit the
PM would rotate past the applied field in which case it would
decelerate, and who knows where the PM will end up. Do you see my
problem? It is possible during one time unit that the PM could
oscillate back and forth a dozen times. On the other hand, if PM angle
is appreciable far from H angle, say 90 degrees, then the above common
angular distance physics equation is more precise (not exact) since the
PM's angular acceleration would change less.
The above physics angular distance equation would be more accurate if we
segment the problem. This would appear like a bar graph and provide a
closer approximation, but not a precise answer, which we need. I think
Riemann sums would do the job in such a case. Lets say one unit of time
is 1 ms. If we break the problem into ten sections then I guess the
above equation is roughly ten times more accurate, but still not precise
like definite integrals. For example, from time 0.0 to 0.1 lets say the
acceleration is 0.9. So we would plug an acceleration of 0.9 in the
above equation for dt of 0.1. Then from time 0.1 to 0.2 the
acceleration is 1.3. etc. etc. By performing the equation 10 times and
segmenting the problem to adapt to the changing acceleration we can
arrive at a closer approximation. Perhaps that provides some ideas how
to properly integrate this with definite integrals.
If it helps here's some more circular equations if you scroll down to
Circular Motion -->

I appreciate any help, but if it's too crazy of a math problem then no
big deal. I'll find some way of solving it. It's been too long since
I've used nothing but basic calculus, but it doesn't hurt me to relearn.
:-) It might be a issue of using double iterated integrals.
Thanks a bunch,
Paul
Thanks for the clear description. I will try to work on it as I have time!
