@@chrisawesome3091 well, I am currently working my first year as a chemist in Austria, and exploring the quantum world is just my hobby so I'm sorry if I get something wrong too, the Casimir effect actually is the result of the non/less existing quantum fluctuations which is simply pushing two plates togheter because there are more on the outside than in between, what I meant is that for a perfect vacuum you would basically have to make a vacuum chamber small enough to not let any quantum fluctuations fit in between, I have no idea how big this could be maybe as small as just 1 Planck volume...

Nothing touches anything else normally when you place something on the scale. There is no contact normally either. There is mostly empty space with the repulsive forces making it seem like there is anything solid. EM force that acts at a distance is happening to make it seem like there is contact so there really is not much of a difference when you use a superconductor, it is just that the distance between the objects is big enough that we can see it with plain eyes.

It is probably you that give the dough a shock. It's most likely the clothes you wear that rub off some electrons on you and they jump off when you touch another person, a doorhandle or apparently the dough. Or, if it's a metal table you're working on, it could be the dough rubbing on the table and then zapping you. It's not dangerous, neither for you... or the dough. It's just static electricity.

Can you please talk a bit about mag levs and the challenges faced when actually using this for transportation in the world today ? Thanksss

[@metamorphicorder]

It's really really expensive and extremely difficult to engineer. You have to have a superconducting surface that's either the length of your train, which has to be then broken into sections for each car or you have to have one single unit with no cars. The length of such a unit has to be shorter then the radius of a circle of which any curve in your track is a section of so that it can follow the track at speed without derailing, and if you have NO at speed contact surfaces between the track and the train, there's a pretty low limit as to how much lateral movement you can allow the train to have or it will simply get thrown off the field that is essentially your track. Basically, you need long straight track with no curves or turns. You also still have to have some sort of traditional track rail surface because you have to have some way to propel the train and stop it as well. You can use magnetic braking and propulsion to be sure. Either in the track or carried on the train. Doing it in the track is stupid expensive if you want performance that makes it attractive to governments so we are talking speeds over 100 mph and getting toward 300 mph to make this price attractive over cheaper but slower options. Each method has its disadvantages. One, building propulsion into the track is ridiculously expensive. Building it into the train requires a huge power source to be on the train, so either huge batteries or a large generator powered either by traditional fuel sources or nuclear power which is defeating the entire purpose of something like mag lev on one hand and really expensive and possibly dangerous on the other hand. Since we dont have mass producible high temperature superconductors yet, where ever you put your superconductors, you need coolant. And you run into other problems with multi car trains because the breaks between cars produce field gaps in either configuration, field gaps lead to instabilities especially under speed. You have to shore up the gaps with some sort of continuous surface of either magnets or superconductors. This CAN be done but its complicated and expensive. Going with a single long car config with a straight track is much better. This is limited in its applications and its attractiveness. It's actually easier to build the auowr conductors into the train especially in the single car case as it's much easier to cool a smaller amount of superconductors than it is an entire track. But then your have to carry the coolant. Liquid nitrogen is expensive and can be dangerous. a mass containment failure in the passenger compartment would be really really bad and in some cases if the nitrogen displaces the oxygen in the car, everyone could die. This could happen slowly like carbon monoxide poisoning. So you end up building a train with extra steps and more risks and expense. So one way you have to use a lot of superconductors or you have to use a lot of magnets. And then there's mass and speed to consider. the effect described in this video wasn't fully explained. The action of a magnetic field in proximity to a superconductor at critical temperature meaning it's currently capable of super conducting will created heat inside the superconductor. It will raise its temperature. This is a complicated subject but several variables effect what happens. Field strength, mass of both the super conductor and total payload, magnetic flux. If these things become too large, the superconductor can stop being a superconductor. This could be really bad. Kinda like if your airplane stops being an airplane. It's a nice idea but it's really complex to implement. Which is why they arent everywhere.

I like, how it went from "yeah, the superconductor affects the scale's reading" to "you've never truly touched anything in your life" Unless (technically), when you've poured some reactive chemicals onto your skin.

These are really good demonstrations and explanations. I believe, though, that you can step it up and teach experimental science. For the work with the vacuum chamber, two things are needed to turn demonstration to experiment. First of all, measurement. Run a timer and show how long the superconducting lasts. Second, a control. Do the same experiment with the box open, or closed but no pump. Compare the times. The levitation on the scale was closer to an experiment, as you did show the weights as measurement. You could easily have provided a control by putting one regular magnet on the scale then pressing down from above with another opposing regular magnet, so the South-South opposition would increase weight on the scale. In both cases, summarizing with a data table or a graph would have been excellent. Please keep up the good work. I hope you will also begin to demonstrate the difference between demonstrations and genuine experimental science.

[@i_am_the_monkey_king]

7:13 The way most people understand 'levitation' is that it's a kind of force that keeps something from falling back on the ground and instead stays in a certain amount of distance from the ground unless whatever force is responsible for such phenomena is increased. So it's like an object being lifted off the ground by some invisible force. Like a balloon with an invisible string tied to a pen. Making the pen itself to have zero weight if it was to be placed directly over a scale. In this case, it's a magnetic force that's making an object levitate. Meaning, the one that's lifting the object isn't something like a balloon, but more like a jack or a crane. The weight is just shifted somewhere else, but still has to touch the ground. Hence, the weight doesn't change at all. I've always wanted to find the conclusion of this experiment. But, I couldn't get a hold of some liquid nitrogen. Haha

Just an idea to get to a full vacuum quicker: Pulling a vacuum in a "side chamber" (a tank or something), connecting it to the main chamber, pulling a slight vacuum in the main chamber to close it, opening the valve to the side chamber and when both chambers are at equilibrium, continue with the pump.

[@sourabhperuri1698]

Same question

[@WouterVerbruggen]

The levitation pendulum isn't frictionless at all and also the superconductor puck never touched the magnet. The friction is from hysteresis losses, as the field is constantly changing from the view of the puck. You constantly push flux vortices in the superconductor and pull them out again, which cost energy because these fluxes are pinned (quantum locking). Also, there's gravity. In a pendulum, the vertical position is constantly changing, so gravity is constantly doing work, hence causing friction. And next to the liquid nitrogen quickly evaporating and not provide cooling anymore, there's also a very sizable heat load from thermal radiation. Remember radiation heat load goes with the temperature to the power 4, and we have quite a large temperature difference here.

Here's a suggestion: accompany your explanations with free-body diagrams. It'll help viewers internalize the way all the various forces interact mechanically, and it especially helps to drill in the whole "normal force" thing. You really do find that a lot of stumbling points boil down to "Did I remember the normal force?"

@@Starioshka How is it lacking in substance. The whole spiel of what they said reduces to newton's third law. They gave a long winded explanation for a simple understanding and you say it lacks substance? It's reducing the answer to its simplest terms which is what a good scientist does. And the balloon doesn't counteract gravity. It uses it. That's how we get atmospheric density which is the reason the balloon rises to a point. We even know why it stops moving up. Helium is a lighter substance and thus it floats on top of others until it's stopped. Anyone who says that this is counteracting gravity just doesn't understand the subject matter. My jumping is a counteraction of gravity via work as I'm in a stable density. The balloon isn't. So not only are you wrong: you're wrong twice.

Wow, thanks for this! I've been dreaming for years about experimenting with superconductors and Meissner effect !

[@VyvienneEaux]

It should increase, due to Newton's third law. Quantum locking occurs because the electrical resistivity of the substance drops to zero below a certain temperature threshold, and so the magnetic flux generated by bringing the superconductor close to the magnet induces an electric current in the superconductor and corresponding magnetic field that continues perpetually, keeping the object fixed in the exact location and orientation corresponding the the field. Interestingly, magnetic fields can do no work. In order to maintain stable levitation, the magnetic "force" from the magnetics keeping the object suspended should be equal to the object's weight, and so the reaction "force" should transmit the object's weight to the surface supporting the magnets.

[@swr1240]

I'm confused as to why anyone would believe the weight wouldn't increase.

[@Zoltoks]

I wouldn't increase if the the scale was in between the dead air space where it floats. But the superconductor isnt strong enough to do that.

[@hrgwea]

I'm also kind of clueless about this no-question that's in desperate need of no answer. It would be more interesting to ask whether a bird flying inside a house causes the weight of the house to decrease because the bird is no longer touching the house. The answer is still easy to guess, but at least not so absurdly obvious as the magnetic repulsion thing.

Isn’t that that one law were everything has an equal reaction n stuff 😂

[@kallewirsch2263]

Yes, exactly correct. Gravity is exerting a force on your body and pushing you down. The ground has to bring up exactly the same force in the opposite direction in order for your body not to fall "through" the ground and be able to stand on the ground. If a ground (eg. quick sand) cannot bring up that force, then there the force of gravity cannot be canceled anymore and you start to accelerate to the center of gravity. The law you are referring to is one of the famous "Newton laws". a) F = m * a b) For every action (=force) there is an equal and opposite reaction. Ond could also argue that the conservation principles are a generalizatio of that one. If a body is motionsless or in uniform linear motion AND we know that there is a force acting on that body, then we have to conclude that there must be another force somwhere which counteracts the first force. Because otherwise the sum of those forces would not equal out to 0, and as the first Newton principle tells us, if there is some remaining force that would lead to an acceleration. But an acceleration is a direct contradiction to the observation, that the body is motionless or in uniform linear motion (which both means: unaccelerated). We know a) the body (doesn't matter if it is a superconductor or not) is motionless b) we know, that the force of gravity is acting upon it therefore we know, that there must be a force counteracting the force of gravity.

I think the superconductor heating up in the first part is really just because there is actually plenty of air for most of the time it's in there since the pump takes a while, and also thermal radiation. The liquid nitrogen should provide the same amount of cooling regardless of how quickly it boils, so while it may boil faster the puck should be extra cold when it finishes boiling.

[@new-knowledge8040]

The higher you place the super conductor, then less it weighs. Thus if the magnets were so strong that the super conductor was hovering way up in the atmosphere, the total weight would be less. Thus there should be a difference if the superconductor was resting right on the magnets compared to it floating at a distance of some measure above it.

[@xthemilox6822]

When the weight increases, is it the weight of the superconductor? Or the weight of the repulsion it emits? Or maybe a mix of both? Side question: Does the mass of the superconductor have any effect on how strong the repulsion is?
