Love how open those guys are to just mess around with equipment worth millions of dollars. This type of stuff inspires young people interested in science.
It's how discoveries are made :P
I wish science was taught in schools like this, so more young ppl would be interested in science.
@@asterix45
Too much liability.
One day some kid gets a booboo during shop class, and a week later, his Karen mom shuts down shop class for the entire country.
@@asterix45 we had a few science shows with Jacob's ladders and beds of nails and levitating superconductors and stuff like that
@@asterix45 I've always felt that there are lots of young people interested in science, it's just not a career that's pushed very much in schools (at least not when I went). Often times the careers that pop up as options that are STEM oriented focus mostly on the TEM part, not so much the S part. At least when I was a kid, I always thought that science is something that is reserved for the true geniuses of our world, so I didn't get into it because I felt like I don't have the inherent "talent" required to become a scientist, even though science and math were my favorite subjects in school (ended up going into accounting because I was told "that's math" - it isn't).
Turns out, you don't have to be a genius - all it takes is for you to be competent enough to be able to grasp the concept after you study, and passionate enough to actually study. Had I known that I would probably pursue it.
Buy a house. Build a 45T magnet under the kitchen floor.
3 in the morning, woke up because hungry. Turn the magnet on.Heat up food and eat it in a metal plate. Now finally you can eat in peace knowing that if you drop the plate accidentally, there will be no sound to wake your family up.
Wow😂 amazing

It was fun having the Veritasium team at the lab! We don't often get a chance to "play" with our instruments and it was great to be able to demonstrate a few principles of magnetism in creative ways.
amazing

Hi!
@@brandonaservantofmercy8561 Hey!
I love how some labs are like "everything we do is HIGHLY CONTROLLED, you can record but DO NOT do anything weird" and then in this one it's like "yeah let's tape some washers into a NERF football"
When I worked in a lab, we often did funky stuff for testing or for fun. A lot of the time, it progressed into something where we could plan an actual experiment that collected data. You learn a lot through playing around.
@@soaringvulture Yeap, thats how we have fun in science circles
not to mention "wanna use a leaf blower?"
I mean they had a potato cannon just lying around with slugs ready to go.
Based on the shots he cut to of the other football, it seemed more like this setup was something they had done before, including tossing it at the outside of the magnet. It doesn't seem like any of the experiments came from Veritasium but were instead this lab showing off fun things they had tried before.
Imagine being so successful on KRplus that not only does google pay you ad revenue, but the straight up sponsor you. That's badass! Keep it going!

ìf i find a rock that sticks to each other today, i'd still be excited, even knowing what it is. rofl
It blows minds to this day, magnetism is (to my knowledge) the only fundamental force that science hasn't identified the unique particle which causes it. If I could study anything at all it would be magnetism, likely the final piece of the standard model puzzle.
@@Ixidora Magnetism is one effect of the elctromagnetic force which is caused by all subatomic particles that carry electric charge. These come in two flavors, elementary particles and composite particles (also called hadrons). I'll list some of them for you here:
Elementary:
Electrons, positrons, all quarks and anti-quarks
Hadrons:
Protons, anti-protons (these consist of two up-quarks and one down-quark / two anti-up-quarks and one anti-down-quark respectively), pions, kaons (these consist of combinations of quarks as well).
There are some particles that we do in fact not know about yet. A few years ago, we found one of them, the Higgs boson which is the carrier of the gravitational force. Now, we are on the hunt for dark matter. There is a predicted particle we are still trying to find called the axion which could explain the phenomenon.
Disclaimer: I am not a physicist, I just read a lot about the topic because of personal interest. I might still be very wrong.
So awesome to see the MagLab get the spotlight it deserves! I had the pleasure of going to FSU and I got to meet so many people who worked there. All incredibly smart and able to convey information to anyone. The annual open house is something of a local holiday.

About 10 years ago I worked at a company that made high speed, fiberoptic magnetic field sensors. Those sensors were taken to this facility in Florida for calibration. Since it was very time consuming to do these calibrations on all new sensor designs, I built a pulsed magnetic system to test the new designs. My system achieved pulses of about 12T in a 2 cubic inch central volume and saved the company a lot of money during R&D. It is great to see this video and it brings back some good memories.

It's probably nowhere near as strong as this one, but underneath the building at which I take my physics seminars at school, there's a big underground lab where they do plasma physics stuff, growing materials in plasma, shoot stuff with lasers, and it also houses what I was told was "the biggest and strongest electromagnet in the southeast"
I got to see so much stuff going down there, it was mind-blowing. I wanted to cry because I was thinking about how many people never get to see this fascinating kind of stuff. I wish science was taken more seriously by the public.

As someone who works in a lab with high magnetic field capacity, I think it’s super interesting how you go from super commercialized 2-8 Tesla magnets (every MRI machine for one thing) to having 45 T be the absolute world record. For a lot of things in experimental physics (most powerful laser, high pressure, coldest temp recorded, most precise atomic clock etc) the record holder is many orders of magnitude larger than the off the shelf stuff. You have to respect how much work is put to get from 10 T to 20 T, and from 20 T to 40 T.
NO, BAD BOT, BAD, SHOO
Normally magnets are .23T - 3T when they are used in a clinical setting. Anything bigger than 3 Tesla is normally used for research only.
@@shawncaldwell9318 this is not true. I work on a 7T magnet for clinical use. (Siemens Magnetom Terra)
@@shawncaldwell9318 lmao ure wrong
@@farrel_ra He said "normally" not "Absolutely"...
I'd imagine he is correct, that the vast majority of magnets used domestically or commercially is up to 3T. Beyond that would be the exception, not the rule.
I see nothing wrong with that statement, he made no assertion that ALL magnets above 3T were used exclusively for R&D so it was pretty clear what he meant given the language he used.
Think, before typing, do I wanna act like a 5 year old today? Answer: No.
Hi! At minute 9:52 you want to show the heat produced by the eddy currents with a thermocamera. You can't see that on a aluminium sheet, because that sheet is like a mirror for the ir radiations, so you will see the temperature of the objects reflected on it and not the temperature of the object itself. If you want to see the temperature of an aluminium sheet you must cover it with pvc insulating tape. It is thin enough to reach the same temperature of the aluminium sheet but it has an emission coefficent near to 0.98 so that it can emit the ir radiations and you can see them with the thermocamera.
Or paint it black.
Yep, this was visible towards the end of the sequence when the temp spiked. It was a distinct stripe reflecting from Tim's body heat.
Oh cool, I would never have considered that. Thank you for your comment!
What is a "thermocamera"? Did you mean "thermal camera"? Has anyone ever described you as "slow" or "special"?
@Bobby Dazzler spoken like someone who is "slow" and "special".
This is less than 10 minutes from my house. I pass by it every day starting my work week.
Very cool video and lab.
Thanks guys!❤❤
Just a detail: one needs to be careful if you want to correctly measure the temperature of a metallic plate with a thermo camera (like done in the video).
The temperature reading does in fact change when the plate is falling even if the temperature of the plate does not change. The reason lies in the principle how the camera works. It collects heat radiation from the plate. However since the plate is also reflecting light from the surrounding like a mirror, the camera collects heat radiation from different bodies in the room as the plate falls. An example is the reflection of the hot body of his companion that you can see. In addition, different bodies need different measurement calibration values in the camera. So, it’s not so easy to determine small temperature changes and say that the reading in fact shows a small change of the plate temperature. It might be an systematic measurement error.
Better use a thermistor or something similar.
How about just a room that is pitch black with no thermal properties?
@@runnergo1398 It would have to be extremely cold as well I think, all bodies emit infrared otherwise
@@daasdingo You're right. No matter how cold we make something, it is warmer than what we can do.
Beyond that, are we sure the high static magnetic field isn't skewing the accuracy of the IR thermometer? At the very least, the instrument needs to be kept perfectly still, to not induce stray voltage in the traces within its own circuitry.
@@runnergo1398 Good thought. However, the falling plate would still reflect the thermal radiation of the walls that are painted pitch black. Painting a wall in pitch black color does not prevent the wall from emitting thermal radiation. Counterintuitively it becomes a better, actually a very good thermal radiator. How well it radiates depends on its temperature (described by the law from Max Planck). In principle, as Samuel K wrote, you could cool down the room to drastically reduce the radiation (it reduces with the fourth power of the temperature, a rule that is actually used to calibrate the thermo camera). Coolinig down the whole room wouldn’t be very practical though.
A better solution would be to paint the plate pitch black so that it does not reflect any light from the surrounding.
Tim Murphy also seems to harbor an impressive force himself, those arms are packing a punch. But in all honesty this was amazing, thank you for the video and theanks to the Field Facility crew for supporting you in making this. Really amazing content, as always.
ok
Training happens with the magnet on. He is using really small weights.
im sure hes power lifting metal bars on the magnet xD
Now we need an experiment: bring the sample or YBCO material close by the working unit, and turn it into superconducting state by applying liquid nitrogen (all is handled with styrofoam vials) and then either try to push it off the active zone (and see how much counterforce it can make) or turn off the magnet and see how much of remaining field the superconductor will store.
You should definitely look into bomblocators used in EOD operations and how they use ferromagnetism to locate bombs. It's interesting stuff
Now you mention it, that does sound interesting. Especially seeing as bombs are well, delicate lol
In case anyone is interested: MRI machines don't just go "up" to 3T, but there are many in research that go up to 8. There's one in France which is at 11.7T and there will be one in the Netherlands in the future which will have 14T
I worked on one in Gainesville that was 11T. The one I work on daily is 3T.
they could've gone a bit into how MRI works... it's pretty cool too
I'm doing a senior design project with a 9.4T mri. Many of the clinical use ones are nowhere near that high though
Everything above 3T is for Research, 3T is standard Hospital Stuff
What is the benefit of MRI machines having higher T? Is it better resolution or something along those lines?

Looking at the thermal imagine around 9:50, you can't see that the metal is heating up because metal is thermally reflective. The "hotter" zone in the metal just so happens to line up with where a reflection of the professor would be, and you can even see it move as he bends down.

10/10 content. Movie material, unique and interesting stuff. Science at the highest level. Not many of these today. Thank you from me too. If there were more people like this in the world we could progress so far.
its far better than watching all the pewdiepie idiots on here
For sure including vsauce team and smarter every day

9:03 This was an actual question on the physics GRE when I took it 6ish years ago. Do conducting plates fall slower or faster in a magnetic field? Lenz's law baby.
Dude's lifted a whole lotta metal sheets from his magnet. Damn is he ripped 💪
I have no words to describe how good Veritasium videos are
Was skeptical of their quality with the terrible production of the Rods from God video but this really shot Veritasium back up for me. Stellar video.
It's propaganda funded by Google.

What an interesting video! I was always fascinated by magnets and magnetic fields as a child. Thanks for sharing. I have to add a minor correction: there were two areas called Magnesia in the ancient Greek world, one is the one you mentioned and the other was in Minor Asia, nowadays in Türkiye, where Greek colonies had established from the 8th c. BC. The second one was the place from where magnetism took its name. There is still a city holding almost the ancient name, Manisa.
I for once am really surprised that Mricans use Tesla, sensible units, for the field strength. Really was expecting a custom unit once set by her majesty the queen.

@@bartudundar3193 ah snap sorry, they somehow always find a way to sneak in nonsense units even into scientific fields. Forgot about that skill for a moment. My bad.
You mean conquered? Because there were people living there before Greeks took over. Some of those settlements have 8 thousand years of history.
@@RandomUser2401 Usually even American physicists use Metric units
I think this is the closest to magic people ever were. Magnets are so fascinating and just listening to these research speak about that feels so surreal. Massive respect for these people and their knowledge.
The Maglab is in Tallahassee FL and is a joint operation by Florida State University, University of Florida, and the Los Alamos National Laboratory.
Hi Veritasium, at 9:39 I do not think you were measuring the sheet temperature. I have been playing with a thermal imager for a month and noticed most metal (even non polished ones) becomes mirror like in Thermal. So what you were measuring was the ceiling reflection not the sheet itself. Note: you can see the thermal reflection of the person holding the sheet at some point.
Example of unpolished metal turning mirror in IR found at home: kitchen sink, an unpolished canadian dollar, the brushed metal of our oven, etc.
I loved touring this place a few years back. It's awesome to see the big magnet running. I don't think it was shown but also the water filters for this place are huge! Takes a lot to keep that magnet cool. Never realized just how insanely powerful it is till now.
He should have talked about ferromagnetic, paramagnetic & diamagnetic materials he was using throughout the video,Aluminium is paramagnetic,copper is diamagnetic like that
7:16 That idea is so crazy it's amost the equivalent of making a enchanted tool in a fantasy world. Like, goes through the process, and now you have a PERMANENT magnet
Congratulations to Derek for being sponsored by google, you have come so far as a creator!
He’s the only KRplusr I’ve seen that gets sponsored by them.
Google blows. They're the exact opposite of their once admirable company motto of "don't be evil". They're nothing but now.

Interesting video. Very nice to discover scientific experiments.
BTW this ad with Google was the most interesting ad I’ve seen inside a video
Could listen to that guy explain forces for hours on end. Fascinating stuff and his demeanor of explanation is intriguing.
I love how safety isn’t much of a concern in this lab
it's Florida, what do you expect?
Lol why are you judging a labs safety protocols off an informational video which barely went over any safety protocols.....
I know FINALLY I CAN KI- Uh what I know haha funny.
@@mjkhoi6961 oh
That explains it
Thank you for teaching me more physics than I’ve learned in my AP physics class
There is really more to explore in our world. What is taught to us in school is just the basic, when we work that's when we know more. This kind of videos teaches us more.
I totally agree that this data/video is beneficial.
that's one JACKED scientist.
Hey Derek, a small correction. Type 2 superconductors (i.e. all which undergo the transition with liquid nitrogen) actually don't float due to the Meissner effect, since the forces that the superconductor experiences in that case don't allow a local stable minimum (hence it can't float). The levitation effect is cause by the flux pinning, since the type 2 superconduction kind of "freeze" the spatial distribution of the external field.
Nerd
That's really interesting! I had no idea that the Meissner effect alone couldn't explain the levitation of type 2 superconductors. Could you explain a bit more about flux pinning and how it allows for levitation? From my understanding, it's the trapping of magnetic flux lines within the superconductor that prevents it from moving or falling, but I'd love to hear your perspective.
i need a lot dumber explanation of that. Really.

**TLDR: Read the summary at the bottom of the text if you are in a hurry
Type 2 superconductors are materials that can conduct electricity with zero resistance when cooled to very low temperatures, typically with liquid nitrogen. When a superconductor is cooled down, it experiences a phenomenon called the Meissner effect, which causes it to expel any external magnetic field. This effect alone, however, cannot explain why type 2 superconductors levitate when placed above a magnet.
The levitation of type 2 superconductors is actually caused by a different phenomenon called flux pinning. This occurs when the superconductor traps the magnetic field lines of a magnet, effectively "freezing" them in place. The trapped magnetic field lines create a stable equilibrium that allows the superconductor to levitate in mid-air above the magnet.
**So, in summary, while the Meissner effect explains why a superconductor expels magnetic fields, it is flux pinning that allows for levitation of type 2 superconductors above a magnet.**
The difference between someone who knows, and one who asks people who know.
17:33 I see a long-lasting effect right there sir.
