James once again answers random questions that I never knew I'll always wanted to know the answers for.
And does it with a great attitude and humble knowledge. Awesome guy.
So avatar is true
this is why I love physics, you get to see cool phenomenons like this. I always learn something cool everytime James uploads
It's weird how it geo locks like that. It would be cool to see you do this same experiment, but with an electromagnetic field instead.. and one that you can control or vary. Such as vary the voltage of the field and see what happens: See of the superconductor moves as the voltage varies.
Nice explanation! Seeing also that you've learned a lot about superconductors throughout the video series on them, great to see! In applications, this residual current can be a huge issue and an important reason they're not so super in AC. On the other hand, there are serious efforts in making so-called trapped field magnets, where this effect is used to create (pseudo-)permanent magnets much stronger than would ever be possible with conventional magnets. The two slabs are not connected in series btw though, they're both independently 'locked' in the field of the permanent magnet, which is shown by their independent movement.
is it possible to induce a residual current to somehow be in resonance with the AC current generating it? In essence how does the residual current change with increase in AC frequency?
Both superconductors are independently creating the EM field effect. If they had been type 1, they're motions would have been more like sliding over/under the magnet. The slight quantum tunneling that happens in other types creates the pendulum effect because lines of EM slightly slide though the overall repulsive effect.
"The two slabs are not connected in series btw though, they're both independently 'locked' in the field of the permanent magnet, which is shown by their independent movement."
That was my thinking too.
That double superconductor chain was dope.
It defies gravity! So inspiring. Do more parlor tricks and explain the physics behind them.
I always love your superconductor videos 😊
i wonder if it's possible to make a "string" of like 20 of those on the giant magnet? i'd love to see that
That has got to be the coolest coldest wind chime ever
Except for needing a coolant to keep the superconductor cold enough :D
This is my favorite one so far and leaves me asking so many why questions, I want to understand more of the why and how! Please do more like this!
This is incredible! Truly looks like magic.
Another perfect little video. Thanks so much!
I have a question. If you were to put the magnets on a scale, and then hover a super conductor on top of it, does the weight on the scale increase?
Yes. The superconductor is held up by a force from the magnet, so the superconductor provides an equal and opposite force on the magnet.
Im pretty sure he, or someone else already did a video on this i feel like I’ve seen it somewhere
Assuming that the magnets didn't hose the scale, the weight registered on the scale would increase. (To get the scale to keep working, you might have to put the magnet on top of a tall wooden stand, so that the magnetic field doesn't throw off the works. At work I found that even a laboratory stir bar magnet can cause a scale to become noticeably inaccurate.)
To be in his garage is probably like visiting Adam Savage’s warehouse.
Toys everywhere that you can’t afford.
I am really digging your channel right now, particularly all the experiments with magnets floating and superconductors. I always loved magnets as a kid, but this has reignited that joy. I hear the kid in you too when you’re excited about the results you get. Keep at it, making awesome content that you make. And pushing the boundaries of experiment and theory
The last part does look cool, but also it appears to be a single magnet A independently linked to both superconductor B and superconductor C, rather than A linked to B and linked to C. Otherwise the movement of C should be impacted by changes in the position of B, rather than just changes in the position of A.
What? I am not smart like you. I will read this a few times and probably still wont understand. I got lost at A.
@@Lee.Willcox I know you're somehow Ironic.He is confuse instead, he got lost at the first statement when the big magnet appeared in the clip.
@@ematise A little sarcastic too 😆
@@Lee.Willcox ;))
Absolutely amazing. This could explain the propulsion and motion in UFO videos. Pilots repeatedly comment that there are no aerodynamic surfaces or visible propulsion.
Can you do such experiment with electromagnet, slowly increasing the electric current, will the superconductor rise up?
I said the same thing. I wonder if it will move, or if the changing current just passes right through it? And if it doesn't move --- I wonder what would happen if it was next to a multi pole setup that rotates, like the rotor of a PM motor spinning next to it.
What happens when you put the two superconductors on either side of the magnet? And then remove the magnet?
How would one remove the magnet? They would both be locked to the magnet
Great presentation JJ, you sure got your knowledge from your Mom, and Dad. Love your vlogs.
I don't know how I miss this video when it came out, being a fan of the Action lab, but this is one of the best! Did not know what to expect but it particularly impressed me. Great job!
This is the coolest experiment I've ever seen.
Magnetism and Magic are related.
Idk what it is about this guy but I understood more than him more that’s i ever have at school
Could you get a super conductor on a magnet track to break the sound barrier by aiming air compressors at it. What would be the limiting factor, air resistance or the g forces overcoming the magnets hold? I bet you could get some insane speeds
Seems like those superconductors have the capacity to either repel or attract. Amazing experiment as always.
amazing video as always
Could you make a video about how to attach a lapel mic to a t-shirt? Haha love your channel and I can’t stop watching!!!
Excellent clue towards how the moon works on the Stationary Planar Earth model. Cheers 🍻
My brain has a really hard time accepting what it’s seeing on that last example with the two superconductors and the giant magnet. It’s so cool how it works like that. They look connected as if by a string but then move totally independently of one another, it feels wrong but there it is!
I wonder if the weight of the magnet increases when the super conductors are locked below it
Fascinating stuff indeed! Your right arm and hand were doing pretty well holding that big magnet up - there must be some popeye strength spinach in that AG 1 soylent green stuff! lol
“It’s like an invisible string holding them all together” I loved that part too ❤
The superconductor has no resistance. So what will happen if you apply some voltage? It should get I= U/0 current. What does that look like?
So theoretically any voltage applied would mean the amperage would approach infinity. All superconductors have an amperage limit though, so that voltage would break down the superconductivity enough that resistance would still be applied, making the math a little different. MRI's actually have a heater that warms the superconductor just enough that they can keep some resistance in order to drive the current up in the superconductor. Then when they shut off the voltage supply and the heater, the current continues to move in the coil just like what James showed in the video. Would love to see him show this if he can figure out a simple way to replicate this in an experiment.
@@justincarter7954 What you're thinking about is a persistent mode switch, which works differently. There is a small connection piece that shorts the coil, which is kept in the normal state like you describe. This way, the current in the (superconducting state) coil can be ramped up. Then this switch is 'switched' so being superconductive and the current lead into the cryostat are retracted to minimise heat leak into the system. Also you will always have the resistance of joints, current leads, etc, and you'll use a power supply that is controlled in current control mode.
@@WouterVerbruggen sweet thanks for the correction!
If you had a superconductor in particles about the same size as sand or small gravel, would it follow the magnets magnetic lines whilst also being suspended in the air above the magnet?
They would if the particles were not too small. There is a penetration depth (of magnetic field) associated with these flux 'tunnels' which for this material is in the order of micrometres. Inside it, the material is normal (otherwise it cannot allow the field to pass through it). The particles would need to be large enough to leave enough space around such a tube for the supercurrent to flow around it.
Let's put really cold sand in an MRI scanner to find out
/s
In one of your previous videos about super conductors, this is exactly the question I asked in the comments.
Thank you so much for answering: Can a second super conductor hang below another one. In my theory, I visioned that one conductor would create a downwards magnetic field, and that it would influence the other super conductor. But this video shows that they move completely independent from each other, and that it will probably work with more super conductors, as long as the magnetic field of the source is strong enough.
Awesome!
*You should go and see the Japanese Maglev L0 Superconductor Train on it's test track they run almost every day many times per hour they tend to race past at 500km/h*
One can easily see from this why these superconductor suspended trains go so fast.. Nice one! 🌟👍
I neeeeeed visualization of flux, this is shocking. I'm in awe.
thank youuu
I have some questions please answer
1. What material do you use as superconductor?
2. Can we use copper wire as superconductor?
3. What happen when we pass electricity through superconductor any power increases?
The pucks he uses are bulk YBCO. Copper has no superconductive state. If you pass electricity through the superconductor it will conduct it without losses until some physical limit (critical current) it reached.
Can you do a video on how magnets work? I know opposites attract, electrons, and all that, but how does it happen? Google doesn't understand my question, so I thought you'd be good at answering this question
This completely changed my view of super conductors, seeing it upside down made me realize they were locked into the magnetic field and not just reacting with it.
Amazing video bro
Omg .... the magnetic wind chime superconductor thing that you had goin on is actually the coolest thing i have ever seen in my life!!¡¡
P.S. i love how you breakout into boyish laughter at some awsome experiment... when you do, I'm just about allways in a fit of my own goofy laughter right along with you.
Good video idea. Can you see into the past with an infinite mirror loop.
Hie thank you for the vid. Question!!! Does the wait of the magnet increase???
This was very interesting!!!
You'd be surprised how many people don't know about this, and are mind blown when you show them.
I wonder what would happen, if you have a super conductor toroid core inductor, does it increase the magnetic flux, and as a result inductance, like ferromagnetic material or decrease it like diamagnetic material? How the Inductance changes with respect to frequency?
no matter how much science i learn, magnets still look like magic to me.
So good!
That's actually really cool
"Any sufficiently advanced technology is indistinguishable from magic". Arthur C. Clarke
Damn i am currently working on a quantum locking presentation for school and now he is making a video for it 😂
Please do a video on the LK-99 that is a possible room-temperature ambient-pressure superconductor.
Still waiting…
Sir, I want to know how much pressure is created on the glass of your vacuum chamber when it is vacuumed to 100 percent. Please reply. I need to create one big vacuum chamber of around 1.5 m side cube for my research work. Please give any suggestion also which can benefit me in doing so. Thank you
I hope humanity lives long enough to understand this and make use of it.
Why don't we have teachers like you in school 😭 the teachers in my school made this stuff so much tough for me 😭😭🙀
@Don't Read My Profile Photo yeah sure
Because most teachers get payed like a mcdonalds worker, so sadly many would rather do something else like youtube
@@NomadAlly yeah man but the government teachers here in India get paid alot. All they do in class is sleeping on their chair.
4:03 ... superconductor level cool 🤓
With the one or more super conductors on top of below a permanent magnet, do the super conductors affect the weight of the magnet? Thanks.
You are so smart and intelligent.
Incredible.
That giant magnet is amazing! Do you also have a giant spherical neodymium magnet? Well-done!!!
this is so cool
Thank you.
Questions we never knew we had!
When you think about magnets, they're really strange.
I mean, they're just two lumps of metal. But through some invisible, undetectable (to the human eye) force, they attract or repel each other.
Magnets don't require metal. Graphene, which is pure carbon, can be made magnetic because it can conduct electricity very well under certain conditions, and can even be a superconductor. However, I'm not aware of any non-metallic permanent magnets. That's one to look up!
Turns out there are things called "Plastic Magnets" (check Wikipedia) which are permanent, and contain no metal, but they are time-consuming to make and not very powerful.
Invisible like gravity
When James is holding the giant magnet upside down with 2 super conductors, just wondering with the magnetic field holding the super conductor in place, does it increase the weight on the magnet pulling them with magnetic field?
The Super Conductor is Super cool
Hello!,
i have a question
Based on my research,
If Brahma Gupta represent that the dots as zero and zero were known as sunya, which means empty, as well as kha, which means place.
Together, he stated that 0 is an empty place.
A French philosopher, René Descartes, stated There's no such thing as an empty space.
Does it mean that we can divide zero by itself?
Also in math and science zero means
Empty quantity.
i wanna see a time lapse of one of those super conductors in the levitating state slowing warm back up to room temp...
It's not very exciting. Superconductors lose all their special properties once they get hotter than their critical temperature. The critical temperature depends on the type of superconductor, but the one used in the video likely has a critical temperature of around −183 °C. See 5:08.
Question, how many superconductors could that work with all at once considering how strong that magnet is.
Is there a way to see this in action, say infrared or something you can use to see the magnetic field while you hold your super magnet
The only super consistent youtuber
It didn't look like the 2 superconductors were fully independent on the giant magnet though. I'm guessing the innermost one creates a sort of turbulence towards the other one when moving
Yeah.. especially when they were moving. There's definitely some overlap, where the same flux lines were passing through both of them- sometimes.
Flippin awesome😎
So here's a question for you. When you lift or hold the magnet are you exerting a force f=ma where m is the mass of the magnet of are you exerting a larger force? Because for conservation of energy to hold, you are technically lifting the magnet and the 2 superconductors.
4:00 because it's super conductor , Both should be magnetically locked even after removing Permanant Magnets ..!!
Is it possible to create a chain alternating between superconductor and magnet each segment
Quantum locking really is incredible
How affortable is the experiment? WHat is the cost if someone have access to all the material?
4:19 way cool !
Does it have to be ybco superconductor type 2 or can I use the copper or tin (type 1) for the same experiment
Hey! I was just boiling a pot of water on my stove and started wondering what would happen if the pot was hydrophobic! Would the layer of air insulate enough to effect the heat transfer? Or idk! What would happen?
Literally and figuratively "COOL!"
And now we know how floating monuments in sci-fi and other fictional world work
Greetings to You! I am a very interested listener of Your show! My chemistry teacher told me at the technical college, that not a less amount of Quicksilver, if it descents from great heights down onto ground, it explodes. Can you explain, what Physical Laws are behind this personal behavior of the element. I ask you, because you make the best videos for describing interesting things in my opinion. So i would like to hear it from you. Best regards🌟🔼
Cold space itself is repulsion to thermaldynamics. Thermaldynamics is a unification of unidirectional flow that is both clockwise and counterclockwise. Repulsion and propulsion from repulsion. Magnetic fields are the bonding force of pressure holding mass together in force fields of pressure. The magnetic field allows the conductors to move as compared to the weight of mass in equalization to resistance within individual magnetic fields. All mass has quatumized magnetic fields of forced pressure cycling circulation patterns holding mass together. The strongest magnetic field generators the greater force of unification of direction of unification flow
About AG1, I'm pretty sure I've tried it before. It's as healthy as Simple Green, except simple green tastes good. Of course, simple green is also a LOT more expensive, so there's that.
(It might not have been AG1, but I'm pretty sure.)
((And by "as healthy as simple green" I mean "if you have 1 or more copies of the MTHFR gene, a cup of this a day will significantly reduce or eliminate depression."))
how does if you tie 2 magnets with some gap, and place the superconduct between magnets. so the order from above is magnet, superconduct and magnet. then hand off in the air. will them flying?
Superconductors and magnets will never not amaze me
The two magnets look qualitatively independent, but this wasn't a careful experiment. A better one would leave one of the magnets still, while moving the other around. If the still magnet still doesn't move at all, that would be more convincing.
I'll bet there's still some small interaction due to the pinned fields, but that's just a guess.
I really hope he reads your comment.
It's sooooo cooolllll!
WOW, that is so cool and beautiful 😯🤯
I'd love to see the real-time magnetic field lines created here...SHOW YOUR WORK 😂
At Fermilab and BNL RHIC we built super conductor huge magnets in atom smashers .
Question, does the magnet weight increase when you add invisible string super conductors to the bottom of it? Does it get heavier as if you hooked something to the bottom of it?
Gravitazional batteries are being built. Can we avoid so High or Deep Heavy Towers, by using a spring made of a sequel of strong magneti neodimium magnets for example , that repels all togheter, and charged with some weight ? 😮 ( spring potential compression ).
Yes
Pretty cool
cool stuff
