  • how does a colder tempreture effect the efficiency of a standard magnet?

  • Wait, which pixel is the superconductor???

  • LJOTI FORSH VIDEO BAIGI KRUTA JAA

  • toasters...

  • WHAT WUD HAPPEN IF YOU REPLACED ALLTHE PARTS OF A MOTHERBOARD WHICH CONDUCT ELECTRICITY WITH superconductor to do the same thing. but cooled the motherboard and processor, everything is cooled by liquid argon or what ever just wanted to know what wud happen ? and how cooper pairs would effect things like logic gates and the like.

  • @7orqu3 To use benefits of superconductivity as much as possible, the scheme must be designed for it in the beginning. For example, coil, made of superconductor, will change it's properties dramatically, semiconductor elements will not operate correctly as well, mostly because of charge carrier concentration drop, thus conductivity in this kind of conditions. And a simple replacement of onboard conducting pathways to superconductors would not hold a massive effect.

  • @DJFactors

    Space doesn't have an ambient temperature. If you're close to a star... you will receive heat from it..otherwise there is none. Thus ..by default - empty space is cold.. basically absolute zero.

  • @asg3hb Indeed it is. The everyday definition of temperature, as a thermal oscillations of atoms, cannot be applied to space as density of matter is really low. But temperature of cosmic microwave background radiation is similar in some way to radiation of black warm body (around 2.7K). Though this kind of radiation will not affect superconductivity even in case of low-temperature superconductors.

  • @SU89eXa you said it much better :)

  • Actually space is almost cold enough (~3 K), so there is not so much efforts needed to chill s-conductor for superconductivity. Though this effect is pretty much unstable, and disrupting under x-rays, and in strong magnetic fields.

  • Is it an YBaCuO?

  • bravo.

  • anyone know how much some of this superconductor costs?

  • i wonder why exactly when the temp drops that it then becomes a magnet field

  • hard to see with the video quality as low as it is. i seem to remember a crisper version floating around?

  • @Syrophrenikan no pun intended? ;)

  • space is cold, why not use superconductors up there? surely there's an application for them.

  • @ConnorXV ikr super conductors in space would make a lot of sense in space for travel donno why we havnt heard about it from nasa or something

  • @MrSyntheticDesign lots of charges particles flying around, they may have too much of an impact on the current in the wire as there is no energy loss in them.

  • @ConnorXV im sure iv read somewhere it has to be actually colder than space.

  • @ConnorXV

    Space isn't cold, and heat doesn't dissapate well at all in space due to the vacuum. On earth, heat dissipates through air, while in space its a complicated process.

  • @ConnorXV This can be used on earth problem is how will u keep the ceramic always covered in liquid hidrogen!

  • its very be

  • The new holy grail of science in my opinion: figuring out a superconducting GAS. . . is it possible folks? what principle exactly does superconducting work on? Imagine a plasma field contained within a superconducting gas!!!!

  • AWESOME!!! I wish I could do that at my house.

  • Agora eu começo a entender o GTA. kkkkkkkkkkkkkk

  • We can have hoverboards in 2 years? (back to the future)

  • doesn´t have a whole lot to do with the foundation video..

  • First step to understand ufos

  • is that liquid nitrogen used to cool it

  • @lula4911 Yes that is liquid nitrogwn

  • where can i buy a superconducting disk or liquid nitrogen???

    Some1 answer please

  • would this work with palladium hydride?

  • that little grey rock sells for 20 million a kilo :D

  • HOLY BANANA THEY FLOAT. We should totally use this to FLY!

  • @postalflag flying with liquid nitrogen? not very healthy from what i know

  • @postalflag yeeess cool the earth down to about minus 220 degrees to make it Superconducting!!!!!

  • Ajit deciding fate of hero, - " Raabert when you catch that villain, throw him in Liquid Helium, and run 440 Volts.Before that put a Wad of bus tickets in his pockets, then he will become a Super Conductor"

  • cccccccccccccool

  • SO IF YOU HAD MAGNETS stationary with a crafton top of them shooting out this nitrogen steam inside a container with the black thing susspended a few feet down would it hover?

  • Awesome!

  • ok, so just by putting liquid nitrogen on it, it makes it so a magnet can float?

  • @7munched9 yep the superconductor loses all electric resistance and the electric flow that won't stop will create a magnetic field that makes a magnet levitate

  • Superconductor's resistivity is zero.

    There were many experiments proving it.

    This is all about Meissner effect and it's consequences.

  • @ghostlikv No this experiment does not demonstrate the Meissner effect. You are confusing this with ordinary electromagnetic induction. The Meissner effect the ejection of a weak field from the interior as it passes through the transition temperature.

  • @Zantorc The Meissner effect is not 'ordinary electromagnetic induction'. It's the effect which comes, when you 'pass through the transition temperature' with your superconductor. And it ejects not the weak field, but as strong as you put it in.

  • We both agree that the Meissner effect is not being demonstrated here (because it was cooled first and THEN the magnet was brought up) and what you're seeing is an induced field (just Faraday/Lenz law). BTW see "Levitating Magnet over Superconductor" by ExploreTheNanoworld for Meissner demo. However Meissner effect wont nrcessarily eject all flux. If a field exceeds a certain critical field it can penetrate the s/c (cooling in the presence of a higher field will trap excess flux inside).

  • continued...

    In the case of a type II s/c (which is what we have here) the flux which penetrates becomes pinned by discontinuities in the material. In effect it becomes magnetised which is what we see here. (This is known as flux pinning). It is the reason he is able to lift the s/c with the magnet, and its the reason its stable when he pushes it. [See my channel for a more detailed explanation of the physics in this video]

  • Liquid nitrogen right? As for super conduction, there has to be some resistivity right? I cannot believe current can exist without it; I know charge flow is dependent upon the push from electric potential, but there has to be resistance as a regulator variable. I mean the correct resistance is required to have a desired effect.

  • float like a butterfly sting like a bee kiss my ass like a joke

  • i just love your video

  • Wow, right on !

    Thats a breath taker .

  • watch the video called "How Superconducting Levitation Works"

  • Sweet thanks.

  • thats awesome!!

    what are the different things??

    the gas is nitrogen, or??

    and the black cuboid a magnet??

  • Yes, the liquid is nitrogen'; but the black material is the superconductor. It repels the magnetic field of the magnet above. I've personally never seen the step where the field of the magnet is used to "tow" the superconductor up though.

  • PHAIL... I was looking for a super symphony conductor, not this shit!

  • I think you are the fail !

  • Well indeed I failed to find my super symphony conductor 3 months ago, or where you referring to some other failure i fail to notice?

  • Amusing indeed

  • i need to get a hold of liquid nitrogen

  • haha, just don't use your hands to grab it, it's pretty cold!

  • idiot

  • @venomousbird you can grab it if ur fast enough

  • No actually its ok because the person is grabbing the permanent magnet, which is not being cooled. Only the bottom component (black block) which im assuming is a YBCO superconductor is cooled down to ~77kelvin

  • que es el Super Conductor ?

    un pedazo de metal? un iman ?

  • Yo no hablo español. Esto es traducido de inglés UN Súper Conductor es una mezcla de elementos. Está como una piedra en temperaturas normales. Cuándo refrescado con nitrógeno líquido llega a ser diferente. Atrae y repele el imán al mismo tiempo.

  • I am currently figuring out a way to create a hoverboard with this technology.

  • @chrispaquette Its not made up lol whos dreaming?!

  • They need to make a room temp super conductor, It would cause a second industrial revolution!

  • yuppers........... NO more fuel ever. Imagine having an electric car you never need to charge or refuel. It would be more of an environmental revolution than an industrial one.

    SOOOOOO get it down to room temp.

  • a major breakthough would be like making a super conductor that could work with no problem at room temperature

  • yeah no shit faggot

  • Even think of super-conducting power lines

  • how did u do that?

  • !quien me ayuda¡ nesesito hacer este trabajo . por fabor digamen los ingredientes y el tipo de material. gracias

  • It's Very intersting discover

  • what is that compound solid??!! May i know the name? And what is nitrogen liquid's temperature? 150K? Please give me the answer~~ thx ^^

  • superconductors are usualy ceramics of some type

  • mercury is a super conductor. mercury is a heavy metal not ceramic

  • Mercury is one of many superconductors. It was the first one discovered, but it has to be much much colder than the one used in this video, which is a ceramic of some kind.

  • I'm not sure which superconductor is used in this video, but something like Yttrium Barium Copper Oxide would work. Liquid Nitrogen is 77 K.

  • Probably is Yttrium Barium Copper Oxide as it superconducts at 63K

  • i just thought about what i said and im wrong i didnt even pay attention to the fact the metal piece wasnt nickel, cobalt. OR iron.... sorry, my bad

  • the "negative" metal in suspension

  • ok i had to think about this but here it is the white thing is not dry ice but has similiar properties i forget what it is though but it will give off co2 when in contact with any variation of hydrogen just as dry ice, the magnet is on its "negative" side with positive electrons facing up, the peice of metal is negative which would normally attract to the magnet yet when he poured that liquid (not nessasarily water) the co2 reversed the electrons of the magnet turning it to negative up forcing

  • do you pay attention when you type, or do you just drift in and out?

  • its a ovnii ! jajaj

  • Searched for this after I was reminded of superconductors when talking about the pyramids... Looks like a good link :)

  • can u please message me back can this be done with dry ice as i havnt got the money to buy liquid nitrogen

  • Sry dude. but dry ice has a teperature of 195.15K and you're going to need at least 138K.

    As far as I know it's not going to work :(

  • yes it can but help me out, what can i use as a superconductor?

  • so as it heats up the "levitated" metal slowly falls down.

    awesome stuff

  • The Bose-Einstein Condensate, right? I don't think maglev trains would be that efficient, because you would have to keep it at the constant temperature of -273 degrees Celsius.

  • uhh absolute zero is impossible guy

  • yeh absolute zero is impossible sir. You dont need a substancxe to be at abs 0 to be super conductive, look up certain properties.

  • absolute zero is impposible, for this experiment to work, the liquid nitrogen cools to around -140

  • It only has to be cool enough so that when a magnet exerts its magnetic field, a current is imposed within the metal, expelling the magnetic field from inside, and creating opposing poles to the permanent magnet.... its simple physics

  • "simple" hahaha

  • принцип работы двигателя НЛО

  • wait a min how did he pick up that mangnet or the magnet thingy with the help of that metal?!!!!?!!!?!!?!!?!?!! see the video at the end

  • cooling the metal with liquid nitrogen makes the metal a superconductor that allows the electrons in the metal to flow without anybattery!!!! and it (ofcourse) creates a magnetic field where it atracts or repels a magnetic substance am i right??

  • but it is also diamagnetism, which is what holds it in place.

  • its cool but... how will this help the world?

  • maglevs... trains with out friction... more power efficient

  • yay i get my hover board now! seriously wouldnt that be bad ass

  • That´s the Meißner-Ochsenfeld-effect.

  • im doin a science expirement on this stuff and heres an akward question but the stuff poured on the super conductor to make it cold was liquid nitrogen correct? well what exactly is liquid nirtogen and whats a way to get or make some?

  • You seriously don't know what liquid nitrogen is? Where have you been during your science lessons? Liquid nitorgen is the element nitrogen (N) in its liquid state.

  • Did you know someone in October claimed to have come up with a superconductor that works with dry ice? It's probably a fraud because it says it's a "lone inventor" with no peer reviewed verification. But look up 200 kelvin superconductor and you'll find it.

  • Does the nitrogen evaporates faster when magnet is applied? Will be liquid nitrogen a fuel to sustain cars in the air? Then very interesting what would be gpm consumption. Still there will be energy needed to make liquid nitrogen.. And in case if to sustain magnet in the air more l.nitrogen is needed(since it heats nitrogen and the it evaporates), what will be in case if there will be a superconductor in the room temperature? Will it also heat the environment? ... I try to be logical..

  • oh my god, what the fuck are you talking about, lol. You may try to be logical, but you fail.

  • could you explain? Yes I just wrote what was in my mind at the time, my guess was not absolutely serious. But I asked am I right or wrong. Because I do not understand it and thought that anyone can explain.

  • sure, the nitrogen is used simply to cool the material down to its critical temperature. It is not a fuel of any type and its evaporation as nothing to do with the magnetic field. At Tc, when a magnet is placed near the superconductor, its dimagnetic properties repel the magnet causing it to hover above.

  • Explanation:

    watch?v=h8WtaL4hJ5A

  • Again..  Sweet

  • watching the vapor off the liquid nitrogen... it changes with the pressure you put on the magnet... either super cooled miniconvex drafts or some strange arse forces going on... i like.

  • wow

  • i wanna make a superconductor

    wht ia needed?

  • A high temperature super conductor, magnet, liquid nitrogen, and isolation.

  • sweet

  • gracias esto me va a servir `para mi laboratorio de fisica moderna

  • alright, so no one better feel skeptical now about the UFO anymore. It's clearly practical.

  • How do UFO"s work?

  • look at the video. I can't do the math FOR you. If so then it isn't worth it.

  • Your saying UFO's work on superconductivity?

  • Magnetism. That is the most basic and general thing for you to observe in the video. How could anyone miss it.

  • Some UFOs. Google: swallowcommand

  • Many different types of UFO, or SAUCER- propulsion systems. They mostly come under the banner of FORCE FIELD propulsion, dynamic counterbary, and barycentric-control, or gravity control. Study works of Stan Deyo, Thomas Townsend Brown, Professor John Searl,Hector Serrano, and Dr. Ning Li, of NASA.

  • lol long conversation but really interesting and i actually think it works kind of like a heli copter because if there magnetic then why do they SUPPOSEDLE spin... i think thay have little slits in the sides to make wind blow down..BUT if it had a thing to do with magnetism then they would need to use earths magnetic force to fly because its live the biggest magnet anyways

  • earth's magnetic field is relatively weak at the surface.

  • yep thats also another reason why ufos probobally dont use magnetism to fly

  • Another reason is that they're all really aluminum pie plates.

  • So you mean the Chick-fil-a commercial wasn't actual footage of a UFO? Wow, it had me fooled!

  • we did this at school once. just awesome, the quantumphysics are...

  • Why is styrofoam always used as the base?

  • Because styrofoam is an insulator, it doesn't conduct electricity so it stops the electricity from moving out of an object an into the ground and keeps it in the object.

  • Thank you - I tried to find some info on this, but, so far, had not found the reason styrofoam was always used as the base. Most explanations seem to skip over this part and just reference the styrofoam, without saying "why" styrofoam.

  • Oh, you're very welcome. :D

    Yes, a short and simple answer is usually best. You learn this info in Science 10 (which is what I'm currently doing, which is probably why I know this).

  • actually, it's more because styrofoam conducts heat poorly so the supercooled liquid used doesn't boil off quickly. also why it's used as a calorimeter and transporting dry ice etc.

  • I find the relationship between a super conductor and a magnet fascinating. I'd love to look more into the properties of a Super Conductor. How did you get yours so cold?

  • If we could make high temperature superconductors, we could cover our roadways with them. Our cars would levitate without wheel friction! That would be sooo cool.

  • @alienbase:theoretically that's not possible. Superconductors are made at -269 degrees centigrade. Even if you do get something that hot, it's most likely to be anywhere but magnetic

  • Yes, ferromagnets lose a part their magnetic abilities at a certain temperature, curie point.

  • that.....is very cool

  • Can you tell me where you got the superconductor from? The typical suppliers have ones too small to demo well.

  • It was really neat when he pulled them out. I did not know that there was attraction as well as repulsion (as leviatation)

  • that's the way the super trains in japan are travelling?

  • Nah, they use regular old electro-magnets, not sure what material but probably iron.

  • actually, the Mag-Lev trains are in China...:)

  • haha they gave you a thumbs down for saying good=جيد

  • Awesome! Cool science vid. It reminded me that superconductors needed to be super-cooled. I didn't know what was wrong when the magnet just sat on top of the super-conductor block and didn't levitate until the guy poured the liquid nitrogen.

  • Liquid nitrogen? Helium? What materials did you use?

  • nitrogen of course, helium would be too expensive.

  • Liquid nitrogen may not be cold enough for some superconductors, helium would be much better.

  • perfect magnetic harmony

  • yo, so could u create a fricitonless motor with one of these in a vacuum? sorry for ignorance if that is completely ridiculous, i just have no clue

  • Yes you can, their efficiency is about 98% there are only a few built for experimental purposes

  • how do they work in a vacuum????

  • there are magnetic forces repelling and attracting the two magnets.

  • O.O omg.... i have 1 Q

    HOW???

  • Where to buy that superconductor?

  • Oh, god.

  • u need to buy to magnets and some liquid nitrogen. and you cant buy liquid nitrogen unless you have a license. besides, what would u do with a supeconductor if you had one?

  • Where tı buy that superconductor?

  • Super-cooled magnets yield a force (measured in tesla units)..

    1 tesla = 1 weber per square meter

    Takes about 14 tesla to levitate a frog!

  • The reason the Meissner-Ochsenfeld effect is so pronounced is because of the magnetic and not the YBCO superconductor. The magnetic is a so-called rare earth magnet which is extremely strong. Check Chinese magnetic material sellers on the internet -they're the major supplier.

  • actually, the meissner effect can be neglected for type II superconductors... it's flux pinning responsible for the levitating magnet.

  • ?????? omg.... smart ppl you make my brain hert

    i confused

  • sorry
