Magnet Myths and Misconceptions

[barbosi]

If you go for a search in archive.org for Davi's Manual of Magnetism, you'll get several copies. But if you chose the edition from 1865, at the page 170 of the book (179 of pdf file), at the experiment 272, Figure 109 you'll find Leedskalnin's perpetual motion holder. Now, because is a myths and misconceptions thread, anyone would notice that Leedskalnin did not invented it and in fact, it was someone else long before his time who did it. One conclusion to be drawn, Leedskalnin found it in the books as he admitted he was visiting the library quite regularly.

Even this concept, "Directory:Leedskalnin "Perpetual Motion Holder" (PMH) Bond Effect" is silly.  In real life nobody calls this a "perpetual motion holder" and nobody makes claim to it.  Thee is nothing to make claim to at all.  In real life nobody even bats an eyelash about this.

Nobody makes claim to "perpetual motion holder" because is so old, the inventor's name is lost, but feel free to call it as you wish as long you could make use of it. Which brings me to "In real life nobody even bats an eyelash about this".

Are you kidding, or are just an average ignorant? Watch the following video and re-draw your conclusion: http://www.youtube.com/watch?v=cpd52QAdVgU

If you cannot do anything with the effect, is your problem. The effect is real, and in my opinion it should not be discarded because an ignorant or shill dismisses it.

Barbosi:

Nobody "invented" this, it's just a property of magnetic material.  You can put energy into a closed-loop magnetic core and store the energy in the form of a closed loop of magnetic flux.  It's just a property of magnetic materials and there is nothing to invent.  That's what people need to understand.

Nobody says "In the 1950s and 1960s that computer memory was implemented using Ed Leedskalnin perpetual motion holders."  If you said that to a scientist or an engineer in the 1960s they would look at you like you were crazy.

For your point where you quote me, "Which brings me to "In real life nobody even bats an eyelash about this,"  I am going to give you the benefit of the doubt and assume that English is not your first language.  "Not batting an eyelash" does not mean or imply that there are no practical applications for something.  What it means is that there is nothing noteworthy or remarkable about the topic of discussion and it does not merit any further serious investigation.  So your linking to a clip about magnetic core memory is inappropriate in this case.

"If you cannot do anything with the effect, is your problem. The effect is real, and in my opinion it should not be discarded because an ignorant or shill dismisses it."

So, I can understand that you used the term "ignorant" because I am assuming that English is not your first language.

But "shill" I take offense to.  So you please tell everyone reading this thread about magnet myths and misconceptions why I am a "shill."  Explain your reasons for stating that or retract your comments.  If you don't reply and pretend to ignore my statements concerning your comment that will tell everyone something about you.

Here is one of the worst offending clips that promotes ignorance about magnetism:

I'll retract my comments if you properly explain how this promotes ignorance about magnetism. I'm not saying it does not, just prove your point.

You got the stage.

In the clip they say, "Nobody knows (what's happening)" and "This is essentially an unknown phenomena in the realm of physics."  He also says, "There is no reason that they should be stuck together."

That's a bozo clip that will make people stupid.

From here:  http://peswiki.com/index.php/Directory:Leedskalnin_%22Perpetual_Motion_Holder%22_%28PMH%29_Bond_Effect

MarkE, "F = B^2/d.  Where F is the force, B is the flux density, and d is the air gap distance between the blocks.  For polished plates d is very small.  For iron the permeability is high and therefore so is B for modest n*I.  Put one layer of business cards between the two blocks and see what happens.  Witness science in action."

See3D, "This is very basic physics.  I understood what was going on in half a second.  I will explain it in as non technical terms as I can.  The two blocks of steel will become magnetized by the current pulse into the wire.  You will not detect an external magnetic field around the blocks after that, because the field is contained in a circular arrangement of the magnetic domains -- aligned in a circle with the wire channel as the center.  The field is reasonably large as long as the blocks are not forced apart.  As soon as they are forced apart (or if as Mark said, a piece of paper were inserted between them from the start), the field will have an air gap which reduces the strength of the magnet field.  Since this is not a permanent magnetic material, it can not stay magnetized to a high degree.  As the magnetic field strength gets smaller and smaller, the magnetic domains become more disordered.  The further the blocks are separated, the smaller the magnetic field, until there is only a very slight residual magnetic field left.  That is the slight magnetic field that is detected when putting the steel pieces together again.  In the good old days of horseshoe magnets (before strong rare earth magnets), there was always a iron "keeper" bar that was kept between the N ans S poles.  This was for the same reason.  If the keeper bar was removed without some other way to close the magnetic circuit, the horseshoe magnet would loose some of its power -- and that was from a more permanent magnet material."

And here is Yoda333 making a fool of himself, "Can we ever, at this website, see that there are a bunch of crackpots making statements here?  I mean, this really takes the cake.  Frankly, there really is no value in the comments section of this website.  It's a conglomeration of doubters that lurk here just for the opportunity to attempt to debunk something, and try to prove their own brilliance, even when they make fools of themselves in trying to do so.  What a waste of time.  You have been very patient with these same people Sterling, and now you finally have them in a corner on something they can't prove you wrong, and they are scrambling and referring to ridiculous notions of "Magnetic Remanence"!!!!!  LOL  Seriously folks, it doesn't get any better than this...  Total Shills, especially those that have in the past been given a badge for open mindedness amongst the doubters...  A plea only to gain position to further debase any good discussions.  I can't wait until these technologies make it to market.  Two things can happen.  1.  The Doubters here Eat Crow  2.  They all go away because they were being paid for the job of being Shills, and they no longer gain value from staying here and slinging negativity, so they go away.  Either way, I get really tired of watching you take a beating Sterling...  You don't deserve it, and it has become clear to me that you are a visionary, and that kind of spirit is not found in doubters like these.  You can point to past great men of extraordinary imagination all you want, but they will be forever skeptic as that is what they thrive on.  And once a new technology emerges that makes their arguments obsolete, I'm sure they will find something else to try to debunk! LOL."
