Has anyone here actually done a similar *experiment*?
Simulation programs are useless in this regard.
Indeed, simulation programs often leave much to be desired. I would
never "bet the farm" on a computer simulation alone. However, it seems
to me that Hoyt describes an accurate explanation for this effect when
he followed-up with:
It's just that you're pushing the BH curve down with H
so the field strength B is lower in repulsion. Remember these
are highly non-linear materials.
The pushing of the BH curve into the interior of the PM when two like
poles are pushed closer together is quite evident graphically speaking
when performing FEMM simulations. I noticed this effect all the time
in my FEMM simulations. The result invariably is that repulsive forces
seem to be weaker
But they aren't.
as compared to the associated attractive forces,
when two opposite poles are placed at the same physical distance from
each other.
To recap, it seems to me that Hoyt's comment easily explains the
graphic as displayed out at:

And therefore I contend that explanation is just as bogus as the
experiment itself.
I'm sure the experiment describes an accurate observation of Mother
Nature's forces.
I feel fairly sure the experiment is does not prove what the author
claims. It is blatantly evident the report is shoddy or the work was
shoddy or both. Little was apparently thought through regarding
verifying the results, and little was reported.
Nevertheless, I'm puzzled that this particular
experiment is making such a big deal out of the phenomenon.
Please understand. I'm not claiming there IS no OU and/or asymmetry in
certain PM configurations.
I'm making neither ou or nor ou claims. I merely question the
experimental results and therefore also the conclusions claimed by
Kopernicky.
I further think, since so much baloney is floating around, and so
much has been spent based on this assumption, that it is worth the
time for anyone who expects to use the principle to actually test it
throughly.
I have insufficient knowledge on the matter
to proclaim such an absurd conclusion.
I'm happy to let Mother Nature demonstrate her own conclusions.
