Magnetic levitation experiment

[GreatQueenFan]

Come on now, you don't need to hide your true identity anymore, Chuck Norris.

[Tmanmauli2255]

is their a 3rd magnet up above? some pictures have shown a larger magnet hanging above but i could see it working with the 2 magnet blocks

[TheLMack]

what I've been trying to do, is levitate a ball that is covered with magnets, all with positive side out over a magnet that has the positive side up. but it doesn't work. Why is that?

[thecapone45]

OMFG!!!!... ): GREAT! i was thinking about doing something like this all last night and here i see someone has already done it,,, Bullshit,,,

[madrobo]

What happens if you do this in a vacuum? Perpetual motion? Very cool.

[datlildodge]

@madrobo no.

[MRDUSTY2301]

THATS Cool

[jaszee]

new power source or future !!! my god .. cool sheeeeeeeeeeeeeeeee

[MsSheltiepup]

this makes me DIZZY!

[MrGandrew]

guys check out levitation with no MAGNETS!!!!!! Serch for redbull pos

[KyleC603]

it doesnt let you buy the products at those sights

[Sven2Perroy]

why is it spinning ? anti clockwise?

[Scrapsies]

@Sven2Perroy

I guess it's because he used a hair dryer to blow in that direction.

[Conscious9Conscience]

I just had a dream about the planets in space in relation to diamagnetism. I am having problems trying to weave through the products to the referred sites to get the products I need to conduct experiment.

[tadge72]

you dream about that? eek. Im usually dreaming a lot of nonsense.

[ThuhDarkKittens]

@tadge72 me too

[leeyoutube]

at 1:15

he said it will stop in 5 minute

[nat6660]

If it was in a vacuum would it ever stop?

[ruburtoe1]

nope

[Fatcaesar]

I think your right, the energy stored in the spin by the air wouldnt have anyplace to go (since its vacuum)

[Sven2Perroy]

or anything air tight

[supergooddeal]

No, but I wonder if a vacuum can be created on the same concept.

[thecapone45]

@supergooddeal What do you mean by vacuum?

[AnnihilatorRUS]

How to buy??

[kjmagnetics]

Very Cool!

[SunnyShawFilms]

How long it rotates ?

[ryoliciousrules]

cars should be made out of this somehow

[Esternamornezz]

Cool, so you just have two magnets holding up a smaller magnet or what? (don't know what diomagnet is)

Here's an Idea, paint half of each side of the tiny magnet black, and the other of each side white, then put the whole thing in a vacuum pump. You can suck out all the air and then hit it with a bright light to make it spin (and should technically spin until the vacuum is broken, or one magnet overpowers the other)

[datlildodge]

i made but mine sucks!

[GVGRUBIS]

can u get dat stuff at local stores

[scotthughesphotog]

Where I need the stuff today

[calibuso23]

the mind of the human being is very conciuos!!!they can invent many things...that experiment is cool!!i wanna try it at home...tnx dude!!i am looking excactly for this video finally i saw it!!!^_^

[LucyiX]

i wonder that i can find a simple levitation device to build it at home!

[MrCalhoun]

Awesome man. You should try to create somehow a vacuum around your magnets and then measure the length of time it keeps spinning.

[colinrocks636]

in a vacuum it would spin forrever. WAIT OH SHIT. If even one of the magents is just a tad bit stronger than the other the block would stop

[monstermouth5]

what would be the problem to this?

[ellislake]

would it be better to use a ring magnet in the middle out of the same type of magnet instead of a square one as its alot less air resistance.also hide a solar panel behind the wood somehow and attach it to a small fan that has a tube hidden in the wood so it blows on the magnet and makes it spin during daylight,how about that ? coool gadget by the way

[bonquiqui321]

hey were didi u get that at

[ExNihiloJimmy]

awesome

[kei1010101010]

It use air to spins it, a suck-er blowing the manet block to spins it. Cool vid!

[Japgunner]

perpetuum mobile?

[MrCalhoun]

Nope, just the law of conversation of energy. But it's almost an perpetual motion for which you can also use the term of perpetuum mobile of the 3rd kind.

[theoriginalJASONXYZ]

no way dude, thats awesome!

[juplm4000]

are the big magnets attracting or repelling?

[SPUDspoonage]

repelling

[buffalofonix]

cool video minus the attempt at a nascar joke

[StrawberryYogurt15]

This is really cool. I love the way it spins. =)

[fartrage]

wow i had an idea like this but for cars so u wouldnt need fual you would jusp point the magnet bcakwords to go worwards

[poloptree]

U mean.. use magnetics in the wheels, that might be a bit hard.

[sparky3690]

where can you buy that?

i keep on going to the website and it doesnt show any product

[sparky3690]

where can you buy this

[yakkit]

if the magnets were in a vacuum would the block spin indefinitely? Or would the rotational motion release radiation and slow down the block eventually?

[fmftrx300ex]

i was just thinking tht ... someones got to try it

[mohan2]

it would slow down eventually.

[yakkit]

Do the normal magnetic induction rules apply to diamagnets? If so, the cube would have to have an induced current (therefore opposing the field inducing it), which would make it lose some energy and slow down.

[dogmountainband]

It would eventually slow down, just due to magnetic induction in the carbon-graphite, and induction against the earth's magnetic field.

[ymi2b]

dogmountainband is absolutely correct. I have done many experiments with suspending magnets like this and the "grain" pattern of the graphite seems the most likely contributer to stabilizing a magnet from its spin. HOWEVER, magnets themselves have imperfections and thus they tug and pull to a gradual state of balance/stability. I found that spinning well-balanced objects on a needle tip gives as much if not MORE spin time as diamagnetic levitation.

[dorogol]

1) You need a way to get the block moving int he first place in a vacuum chamber.

2) Because there is "some" resistance from the two magnetic fields, it will eventually slow down. Just would take a very LONG time.

3) There is no real radiation, nor what that even matter if slowing down the magnets rotation.

4) As "ymi2b" stated, since there is natural resistance from the magnetic forces, it will slow down no matter what.

It's kinda like the fact 2 magnets cannot be aligned 100% perfectly.

[killabilla]

what kind of an scientist say inch foot blabla.

learn SI, that I stands for International

[gjdj3]

Good point but I think he was using inches and feet to make it easier to understand for the largely american viewing audience.

[2cute313]

can you move the magnets farther apart?????

[em3377]

Now we all can stop working. These magnets will do the rest for us. I't amazing how simple life will be tomorrow. American govenment will resign and peace and fredom for everyone occure. Hallelujah!

[hereiam355]

You still don't know what you're talking about

[em3377]

Damn, no shit again... LOOOOL

[johnjeter]

Do you have an unhappy childhood?

[Colombian459]

science fair?

what would the problem be?>

[dogmountainband]

Earnshaw's theorem -- magnetic levitation cannot occur unless there is a stabilizing force from another axis. DAN

[Colombian459]

:DD

thanks.

[likiepie]

coolllllllllllllllllllllll -_-

[Timbo17932]

where can i get pyrolytic gaphite?

[21030]

ebay

[21030]

or you can use bismuth

[Nanovirus5995]

is it was not for air risistance, that magnet would spin for a lot longer. (it might not be right, but maybe forever)

[Raghav91]

yeah... it would be so awesome. you could try that in vaccum.

[FFXPWNS]

great places to get magnets :emovendo(.)net emoveno on ebay and kjmagnetics(.)com (i recommend emovendo(.)net

[Hakaisou]

even if there was no air around the magnet, it would stop spinning eventually. that's because as it spins, the outer regions of the magnet are constantly changing direction, naming going in a circle, and as such there is a constant loss of kinetic energy. this is probably why you don't see many (if any at all) generators that operate on this principal

[CandyGurlCan]

Then where does the kinetic energy go? When you lose energy it goes somewhere.

[Hakaisou]

Into the acceleration of the magnet's spinning. The matter wants to remain moving in a straight line, but because it's solid, it has no choice but to accelerate away from that straight line of movement. This exerts a small pull that eventually will counteract the rotational force.

[Nathanael12]

Hmmmm thats a very good point. But when the accelleration of turning is done where does the energy go? Its stuck in that spot right?

[Hakaisou]

energy would go the same place a top's would, it would just disipate into a different form, if i had to guess, i'd say small amounts of heat over a very long time. It would still spin for an incredibly long time, long enough that you may as well say it's spinning forever (unless you wanna sit there for a year or so, i dunno, just guessing at this point), don't get me wrong, but it will not spin forever in a vacuum.

[ducttaperulestheworl]

Just wish to have them

[mariomario64]

Awesome science project! If this array were placed in a vacuum (after it started spinning when you blew on it like that), would it theoretically spin forever ? Is there such a thing as magnetic friction?

[dogmountainband]

It would spin forever in a vacuum IF you could eliminate all magnetic effects from other nearby elements (diamagnetism, paramagnetism, ferromagnetism). Which would be impossible!

If I ever find a cheap bell jar and vacuum pump on Ebay, I'd like to try just what you suggest--except try to spin the magnet with a laser. It might take weeks to get it spinning, but I bet it eventually would!

[DeimosSaturn]

How is it that you haven't dominated and destroyed the earth with this astoundingly advanced military hardware?

[electricpete1]

Earnhardt's theorem - LOL.

Really less than $10?

[playwithfire9]

i have alwayse loved playing with magnets

its to bad its so expencive 4 transportation

[7405926]

its similar to the superconducting low temperature deveice thats cooled down with nitrogen,but the only difference between this test and that,is that the cooled superconductor never slows down,it keeps a steady speed,i use computer chips and nitogen to work with,and a magnets to create the same affect,but it keeps cooling down,and when that happens it slows down

[jasondubose2007]

you're saying the drag is a function of temperature?

[squirrelsam99]

hurray for neodymium magnets =D
