Bowl-Array experiment

[Tj1056]

can you make it free float?

[jtardman]

stop making videos and spank it to your family members

[Scanon66]

he's german.

[djpeyoooo]

bon encore un qui n'à pas été à l'école !!!

[kilsikon7]

wasn't this an experiment to prove something from a forum? dude's before you start insulting READ!!!

experiment with a half bouuuuulll !!!

[Grundalizer]

What are you afraid of Tommy? Sie Germans?

[ih8umor]

does mercury conduct magnetism?

[frankensteinmoneymac]

@ih8umor It looks like it has been a while....and no one has answered this question(that I can see anyway) so I figure I will take a shot at it. The answer is no..... Of course you can MAKE mercury into an ELECTROMAGNET....if you ran current through a tube that forces the Mercury into a coil...(or for that matter if you mixed liquid mercury with some substance that would not dilute its conductivity too much , but that would make it hard enough to mold into such a shape).

[ih8umor]

@frankensteinmoneymac cheers for that

[infoseeker228]

no,only cobalt,iron and nickel are magnetic.

[ih8umor]

@infoseeker228 ok thanks,

[44R0Ndin]

@infoseeker228 and alloys containing them, of which NdFeB is the most powerful discovered to date

[correocasa3]

for stability try to give some angular momentum to the sphere so it stays in some like orbital spin stability, I'm supposing wildly however!

[sakadafreak]

stability is good there, it's just unstable... ? lol

[therealcedz]

correction "stability isnt there"

[bartomanboy]

Now seriously, what did you expect?

[Inkubat0r]

мля... еслиб как на левитроне, то да, а так хуйня.

[pcpolarbear1]

what a retarded penis comment.

[gimmeurdosh]

Would of been more impressive to have the ball floating on its own. It is possible, ive seen it being done on a toy in the gadget shop. Took me 10 minutes to get it floating, and once it was it could spin, and rock back and forth, as if suspended on a string. Once i left, someone pushed it too hard and it fell.... 10 minutes work destroyed!

[qwertypenis]

Those toys use a diamagnetic substance like bismuth. This means its repelled by either pole of a magnet. Stability cannot be achieved with a piece of steel or another magnet.

[RichyBabess]

Damn. Would it be possible to do the same thing with a person in some kind of metal suit?

[qwertypenis]

Well its a very weak effect. You would need massive magnets and a massive suit. Even then you would probably only levitate a few mm.

[mnash123]

"it would just shoot to the next magnet if i put it there without tube" what are you guys saying is fake? morons

[cmlegend]

boring

[StudioMarkovTrg]

you sound like a fag

[flyingcatofhim]

ppl like you make god cry

[oOOFrunXOOo]

Fake

[XxMrMaliciousxX]

Fail.

[flowerbower]

There is a point of equilibrium: big deal. It is well known that all such points in a static system like this are unstable. One might as well try to balance a bowling bowl on the point of a knitting needle. Of course, even the latter is possible if the ball is set spinning. Hmmm, I think that I shall call it a Levitron ...

[googlephi]

Yes, Earnshaw's Theorem precludes an equilibrium point for any static ferromagnetic system. (The bowling ball is a good analogy, BTW.)

While he said there is a point where it is easier to hold onto the magnet, he didn't say anything about perfect equilibrium.

[flowerbower]

Well, quite a few situations evade Earnshaw's theorem (which is more difficult to prove than it appears to be at first sight).

[flowerbower]

Oops, pressed 'post' by mistake.

continued: The point is that anything less than stable equilibrium just will not do. I don't think that any more subtle stable-stability situations can pertain in this case; even if one includes the effect of the gradient force (in the electrostatic case) which was unknown in Earnshaw's day.

Anyone who can find a non-spinning 'loophole in Earnshaw', for your situation, will earn a million in the novelty market. Spin the whole array? I wonder ...

[flowerbower]

Looking at your stated age (haha), reminds me of something surprising. When I was a schoolboy, I could have met (theoretically) somebody who worked with Faraday (albeit as a 'lab rat').

John Tyndall's young wife (after fatally poisoning him) lived until WW2.

Kind of puts the rapidity of progress in electromagnetism into stark perspective, doesn't it?

[flowerbower]

Hmmm, I expressed that badly: what I meant was that I could have met him theoretically, not that such a person existed theoretically. I had a specific person in mind.

[Noijen112]

lazy borring ass

[slartie42]

that was so random.

[rebirth3X]

How exciting was that ....!

[ketamunke]

omfg this happens 10 billion times a day in particle accelerators, focus arrays, and toys. Science is dead in the Steorn forums. Just because you make up words doesn't mean you make up new science. This is sad :(

[Mike2008and2008]

The museum of science and industry in chicago has the same idea displayed there ... a steel ball balanced on this same type of idea... it does work!

[xtreme199326]

lame

[MazGhost]

Le Sigh

[rrmackay]

You can buy this as a toy from the local chemistry shop, a spinning magnet levitates above a large permanent magnet. no need for opposing magnets or anything else, the spinning top balances itself above the single magnet. But its just a toy - just like this is.

just search you tube for "amateurs with a magnetic levitating spinning top"

[Particulatematter]

problem was the half sphere, he called that 3 dimensional but without an identical top piece the field is incomplete and dissipates irratically, IE: the instable sweet spot. a top piece with the right inclination will not only suspend the center pin but will spin it perpetually (well as long as the magnets hold their magnetism). With the right alignment of the interior drive magnets and a properly polarized hemisphere casing can be bonded together self enclosed by the casing locking together.

[busteriky]

thats cool what about a full sphire with apposing magnets

[fleiteh]

try something that the magnets would repel, not attract. :)

[Kryptocleric]

like what? If you think of something, Nobel Prize for you.

[fleiteh]

I was just thinking of another magnet with opposing polarity to the stationary ones.

[frankensteinmoneymac]

Bismuth or certain types of carbon work well at this. They are reppeled by both north and south poles. Unfortunately it is not very strong of an effect and generally only very tiny pieces in the pressence of very strong magnets can be levitated. It can work though......Ive bought a small demo with (i think) about 4 magnets set a certain way with a piece of carbon that floats....it is very tiny though and kinda hard to see.

[hotpost101]

cool!

[catcusgreen]

"Earnshaw's Theorem States that there is no STABLE equilibrium"...

Then why not make an unstable arrangement with a rocker system to compensate?

[frankensteinmoneymac]

Basically the same thing is accomplished with a few models Ive seen. No rockers though just electro magnets and an optical sensor which turns the magnet(s) on or off according to how close the object gets to the magnet... Essentialy making it float.also a coil of wire with AC current will hoover over a thick piece of aluminum.

[spokehedz]

This is not overunity. This is a magnetic levitation device. If you introduced a spin to the ball, it would most likely hover for quite a while.

NOT OU!

[futurehorizon24]

WHAT IS YOUR PROBLEM MAN!!!!

The guy never once mentioned overunity. Dude go watch some mtv.

[fastsolve]

"Tags: Steorn magnets "

Yes he did! Steorn is all about overunity.

[futurehorizon24]

Dude please he did it because the experiment was mentioned on the steorn forum. And who can you possibly think would beleive this is overunity? People like you!!!

[johndoe528]

it could work; the problem is that it must be suspended by being repelled; that way, the closer it gets to one magnet, the more it is pushed away, leading to a balance.

[R0B0duck]

ive got an idea kinda of like this. but it hase to do with also arranging magnets on the ball. all magnets on the (plastic)ball would face the same pole outwards and the magnets in the bowl would have the same pole facing inwards.

[matthias2986]

i have thought of doing what you just said since i was a child, never tryed it yet. /claps for the idea

[matthias2986]

check this, take a CD attach magnets several magnets facing - side down around the cd(for instance) then make a table with many many magnets all facing - side up (for instance lol) then spin the CD and let hover over table of magnets. would have to be well balanced, i think it would levitate

[knoxjeff]

It certainly would if properly balanced and with fast enough spin. I had a spinning magnetic top similar to this and it worked. It's really cool to see it levitate.

[roidroid]

that ball bearing would have levitated if it were a superconductor.

[OrganicDrew]

I don't hear any outrageous claims i think people should open their mind and just look its an experiment not a claim so back off. "if it were not for people trying to break the laws of physics newer laws would not be written and the world would still be flat according to the roman catholic church"

[vitr1ol]

If you had a load of iron filings, and carefully introduce them to roughly where you think the balance point is, and let them go free, are you not more likely to find it than by hand? Getting a large ball like that right at the point would be tricky.. by using many small particles, chances are greater.

[homersparents]

they woudl stick together and go go twards a mag.

[ociemitchell]

It would still not work. Permanent magnets alone can not levitate anything. Earnshaw proved this mathematically back in 1842.

[1x1johnny]

try to learn english, piefke!!!

[R0B0duck]

think of it like this. You are trying to ballance a bar on a point. On this bar there is no middle (which seems impossible)but it is permanent magnets we are talking about. Soooo. it will never balance. same principle. except invisible.

[roidroid]

it's like balancing 2 perfectly flat balls on one another.

[yootoobfuckyou]

Bowlogna!!!!

[OrganicDrew]

awesome, I would love to see this in the practical application of a friction free magnetic bearing, well you would have to also eliminate air friction with a vacuume to be 100% friction free. Now combine two magnetic bearings as shown above with a brushless AC motor provided by Tesla and you have Over unity power generation because the extreme reduction in friction is then applied to momentum and not heat.

[hyperkinetic]

Ignoramus! Just because you've eliminated bearing friction doesn't mean you automatically have anything close to 100% efficiency. There is still the resistance of the wire which causes loss. 'Over unity' is a concept used exclusively by the scientifically illiterate and other weak minded nut jobs.

[matt4magic]

Magnetic bearings is not a particularly new invention you know. Patented back in -41 and used in industry since.

[Datacore09]

You can levitate a magnetic disc when its spinning. There are numerous toys on this principle.

[Plataea]

Ernshaws Theorum basically dictates that no arraingment of permanent magnets will result in magnetic levitation without some kind of mechanical anchor, nice try though!

[lukechilson]

Earnshaw's Theorem States that there is no STABLE equilibrium with any arrangement, there is a "sweet spot" but it is unstable, As is stated numerous times by the videographer who does appear to know his stuff and is demonstrating the limited degrees of freedom that can be attained using his configuration

[CealeX]

Amaizing deduction!!
