Floating Levitating Magnet

[randallmckay]

a million different inventions will come out of this. This is the future.

[imsmoother]

If you like this watch my induction heater videos

[raicho20]

Good now touch the liquid nitrogen and make an instant ice finger! (Great vid BTW!)

[TheJamesstark]

my bed is like that :)

[iloveRPG1337]

how do magnets work?

[JTMoneyCOD]

where can i get a superconductor?

[Iceinilla]

its because both magnets are the same (there both north or both south) making them repel

[BorNovStudios]

@Iceinilla its a superconductor, stupid! 

[Iceinilla]

@BorNovStudios oh, i didn't read the description. *feels stupid*

[megamustach123456789]

pretty good for a kid... i guess

[TheCrazybiff]

wats the liguid you used



[iSewil]

WTF TROLL PHYSICS

[BlueToastProductions]

Press 6 for "Meow"

[alyshaandjag]

i thought it was big

then i saw the fingers

[chlloe6677]

they did this at the mall it was frozen -350

[supercooldude2121]

DOES ANYONE HAVE A COPY OF BLACK COPS THEY WANT TO SELL ME

[cjpatz]

Looks like unobtainium from avatar..

[MrTrykster]

nice

[polnodle]

I just saw a 14 minute ad, my god.

[DeathMagican123]

I NEED INFO HOW 2 DO THAT

[DeathMagican123]

How do u do that

I need info

I have a science fair on wendsday

me and my budy is planning to get first place

[GhostSigma]

@DeathMagican123 u need liquid nitrogen.

[BeakyRed]

Apparently, this is how the floating mountains of Pandora seem to stay afloat. Something to do with the Unobtainium in them and the magnetic charges.

[TheHDRuneScape]

i love doing this because North and South ends attract and North and North and south and south dont so they can float that way

[BabiaaVaniaaa539]

[Billy26797]

That's pretty cool

[cracyniggaz420]

wow thoes lil girls are crazy

[brtos]

How much does a superconductor cost?

[cromartie800]

@brtos

That size is $50-75 the more $ the higher the temp it will work!

[CursedSeal7]

sadly, liquid nitrogen isnt something you can legally get as a normal pedestrian, either you need a special permit to buy chemicals like that or you need connections with the people that already do.

[Cefiay]

the voices are just like little kids who are playin' CoD!

[nealshireman]

I have made a track for levitating magnets that go around in a circle with this. it's pretty cool(lol, thats punny)... the only downside: I have to keep filling it with liquid nitrogen -__-

[jacobonix]

ufo

[thomasedwardd]

thats incredible

[PsalmsOfPlanets072]

yay superconductors

[super6plx]

the way this works is that the magnet floating on top makes what's called 'eddy current' in the superconductor. this is because when you move a magnet near metal it makes electrons move, BASICALLY, so that's called an eddy current.

now, since superconductors have ZERO resistance, that eddy current goes round and round the superconductor NON STOP, and because an electrical current makes a magnetic field, that non stop current causes another magnetic field to oppose the magnet, thus it floats.

[jpmorgan187]

@super6plx

so, if you take a away the magnet, do the eddy currents keep going round and round?

[super6plx]

the energy you push the magnet into the superconductor is what creates those currents, so I don't know if taking the magnet away would be an equal reaction and would stop all currents inside the superconductor completely... it might or it might not. I just know that if you put a current in using a battery and some wires and take away the battery then the current really will never stop, but with a magnet since you physically force the energy in, maybe taking it away would cancel it and stop

[lillipili]

im a gr12 phys student....and this excites me greatly. hahahaha i wanna do this in lass

[DrSillyus]

@OllieMarshall92 its not two magnets. It's one magnet and a disk of bismuth

[Pucadupr]

Liquid nitrogen isnt so dangerous you can touch it quickly with no problem. We use it alot in the labs.

[nealshireman]

@Pucadupr yeah, its the laden-something effect

[nealshireman]

@Pucadupr yeah, its the laden-frost(right?) effect

[santirat1]

watch my videos of toung tricks!!

[nealshireman]

@santirat1 no, thanks.

[MrGandrew]

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

[RamiAtrash]

don't play with liquid nitrogen around kids !!!

[twizzztable]

cooooooooooooooooooooooooooooo­olllllllllllll

[Subliminalfeet66]

Why the magnet do not float without nitrogen liquid ??

If the magnet is of same polarities it float without nitrogen !

[MrAhmadjoe]

dude your a nerd

unless your over 28

[monkeyzNdogz]

you have to supercool the magnet to achieve superconductive-nism.

[snoopersts]

what magnet is the silver one?

[Dth091]

It's a standard rare earth magnet

Neodymium.

[snoopersts]

can someone tells me the materials of it.

mail it to my profile account

[steven123dragon]

dry ice shit and more shit jkjk im bored

[evilmonkey298]

i still dont get how it works is there 2 magnets and is that water and why is it bubbleing

[producersunnyshadows]

its liquid nitrogen.

[timar03]

2 magnets. the "water" is liquid nitrogen. the liquid nitrogen is just there to freeze it it doesnt do anything else. the reason why it floats is that at those freezing temperatures the magnets behave diffrently than they do at room temperature. to learn more about that phenomenon search for superconductivity

[bestdancer10303]

whoaa who r u :O

[pulena51]

The black "magnet" is actually an Yttrium-Barium-Copper-Oxide ceramic that acts as a super conductor when its at the temperature of liquid nitrogen, whose boiling point is actually 200 degrees colder than the freezing point of water in Celsius and the other one is a rare powerful earth permanent magnet. The super conductor creates currents which cancels any magnetic fields produced by the permanent magnet. Thats all I know though :p

[landtopilis]

you know alot

[okkima]

liquid nitrogen, that's -200°C or 73°K temperature and boiling because of temperature difference with hot air. Magnet levitates because the magnetic field is not allowed to change inside the frozen magnet, and frozen inside is fighting against the change.

[Netfruitcakemagnet]

its liquid nitrogen not water.

[educassiano]

Someday soon I might be going home from work floating with magnetism. Who'd say that now?

[SophisticatedSpider]

With enough money, someone could build a magnet room and suit which would allow the user to float such as in outer space. I wish i had about 2 mil to test that out.

[askmiller]

ya see, if we could descover a super conductor that doesn't have to be cooled very low, we could put it in a vacuum, spin the magnet and get unlimited electricity. You never know, may be reality in 50 years.

[nat6660]

All you have to do is use iron magnets along side of a slight electric current in a vacuum. As long as the power generation is higher than its consumption you would laughing. Basically it would take 1 jolt of electricity to start the generating magnet system spinning and either through friction or another means produce the electricity. Think green we don't need more poisons in the world

[biancais]

Incredible!, thank you for showing us.

[RivekTheFallen]

Neat little science project, imo.

[ranausman143]

the little guy talks too much LOL

[tellemscrappy]

the little boy talks to much

[PokerVertigo]

pretty irresponsible to let your kids go near liquid nitrogen.

[brusseb13]

her voice reminds me of that chick off scrubs

[snwbrdr4life23]

elliot??

[brusseb13]

lol no that little intern

[lboy9889]

where can i get liquid nitrogen?

[ManDudeYeah]

"How does it just do it by itself" lol

[MrSuperuberduper]

look i got both of em 1:00

[drPainful]

the magnet floats on its own magnetic field and if you were to spin it, the magnet would stay spinning for quite a while because there is no electrical resistance

[ManDudeYeah]

.... Yes I know, I was only quoting someone else. Thank you though.

[limhanxian]

try use a pool filled with liquid nitrogen and magnet and u wear a cloth full with magnet see u can float anot XD

[extremebaby101]

at :37 to :40 duz the little kid say dude u gimme gas??? LOL

[xdmachoman532xd]

lol cool

[crazyfart123]

cold not cool

[ilikepie3010]

great job

[DragonsFire78]

I have an experiment I'm going to try to make the magnet float, continuously. Scientificly, a magnet can rarely loose its magnetism, so the magnet would float without dropping, ever. Also it wont be with liquid such as this one, but just magnets.

[johnkollor]

wow cool

[elopewithmemsprivate]

0:26

"its not cool, its stupid..."

"its COOL."

[jankozzu9]

COOOOOOOOL!!

[monypril]

speed i belive those 2 are magnets and magnets repel each other.

[jackhampson]

if they were both magnets repelling each other one would flip so that the opposite poles face each other, it would not stay suspended.

[gasparmc]

very nice demonstration

[sheik480]

*house*

[sheik480]

I think it's housholdhacker.

[hpidude]

where did you get the liquid nitrogen?

cuz its hard to find...

[Stepanik7]

0:04 funny voice

[speedstakerguy]

i have seen then lol and its fake. the magnet would be attracted to the metal not repel it...

[KmarKitkat]

woopsy..i thought it was a magnetic beam under the floor...lol

[sheik480]

If it weren't a superconductor, then you'd be right. Read the description.

[speedstakerguy]

now lets see people make floating transportation like that!

[Steenberge]

The japanese and chinese already have trains that use this technology along with eletromagnets to move them.

[speedstakerguy]

i meant like really floating highish... and like able to hover

[Steenberge]

That would be cool. Right now in 2008 energy is expensive. But in the future when we all switch to more efficient energy like hydrogen that you can make from water+ small amounts of electricity, magnetic motors, solar power with mirror magnification. Energy will be cheap and Your Idea will be a reality. Cool idea.

[o0tinerz0o]

you cant get high off of nitrogen vapors. Otherwise you would be high 24 hours a day. The air you breathe is in fact 70% nitrogen by composition. It is inert as far as human biology is concerned.

[GuitarWhisperer]

Magnets are cool.

[webkinzwatchertv]

WOW!!!!!!

[lufei123]

this is call superconductor, the thing dat's flowin is a normal magnet, wat actually causes it to flow is the big piece of black magnet under it, how it is done is by pouring liquid nitrogen onto the black magnet to make it 0 resistance, afterwards, it is done and ready to be played with, so any magnet dat place about it will flow with no energy lose, u can learn it in physics and chemistry, but u dun get to experience it

[MaskguyEvan]

Weell, the resistance isn't exaaactly 0, is it? Given, of course, that we accept absolute 0 for thermal energy is an impossiblity

[IthacaCollegePhysics]

Actually, Superconductors have zero resistance at finite temperature. Zero resistance and unique magnetic properties are what superconductors do.

[IthacaCollegePhysics]

Actually, superconductors do indeed have zero resistance. Zero resistance and unique magnetic properties are what define superconductivity

[fragm3nted]

does this happen becouse the metal's particles are frozen and unable to change, therefore the magnet attracts and repels in an even pattern that causes the magnet to stay?

[JMercin12]

ur daughters have really cute vocies and im a boy and tahts werid to say but they r cute

[kc7fys]

Hearing the kids musing about how it happens is the best part. Whoever you are--you're a good parent.

[hd883cycles]

come si fa?

voglio varlo pure io me lo spieghi?

grazie

[scyldschefing]

Cerca per "superconductor."  Questo e` una monstra del "Meissner effect."

[XxbombradierxX]

wow!!! I'd to babysit those kids...lol

[Gannondalf]

Meissner Effect!

[tweevr]

Wow, I wish I knew how that works, what class do you gotta take to learn about it lol!

[Naruto159357]

i get liquid nitro from dusters..

[derjew]

lol!

you mean some organix compound called trinitinitoluneeeeeseses or watever. trust me, LiN needs to be under over a 100 psi to liquify

[Shotgunmage]

indeed

[imsmoother]

The black material is a superconductor ceramic. At room temperature it does not conduct, but at extremely low temperatures it has zero resistance. Superconductor ceramics have compositions consisting of oxides of barium, copper and yttrium. Other superconductors have other compositions.  All of them are extremely brittle.

[frat88]

Very extreme :) what is the black object?

[wbeaty]

My own HTSC disk crumbled away! I later learned that you're supposed to bake the water out using an oven. If you don't then the next time it freezes, it shatters into sand. (Even humidity seems to slowly attack these things over many months.)

[mariofish]

where did you get the liquid nitrogen

[imsmoother]

I work in a hospital and got it from one of the research labs. One of the doctors let me borrow a transport container for the weekend.

[gogolesser]

Loved it!

[hadhad69]

awsome

[stop4stuff]

very cool
