Of course you need the worlds strongest man to control the worlds strongest magnet. Dude’s jacked 😂
@Piccalilli Pit and gear. No doubt he’s putting in the work at the gym, but that muscle at that age is 99.9999% gear.
@Khang Phan lmao so true
Bro is jacked because he is gonna be Magneto, he has been working hard to become Magneto after all these years
so truue XD
That is ridiculously cool. And I love how scientists are basically adults that never lost their childhood curiosity.
I think most people would prefer interesting work But not everyone gets so lucky lol
@Eagan L so true.
@Trevor Sequino Ah, the documentation part where all children stop having fun.
The difference between screwing around and science is whether or not you write down a hypothesis and conclusion.
Hah, you perfectly described how I feel!
Discovering magnetic rocks 3000 years ago must have seriously blown some minds 🤯
@Dylan isn’t that gravity?
@Tucker Garcia I listed a bunch of subatomic particles that carry charge earlier, including the electron. Electrons are one of the charge carrying particles and photons are bosons that apply the electromagnetic force.
Why did no one mention electrons here? Photons are not electrons and electrons carry electric charges as well and as far as I’m aware they are a subatomic particle. Protons do have a charge, but are made up of quarks.
The important thing to understand about electromagnetism and gravity is that they are both caused by an interaction between a particle AND a field. It’s not one or the other individually. The EM field is affected by the motion of particles through space, hence why electrons moving in a coil generate a magnetic field (as evidenced by this video). Now I’m not 100% sure, but I would argue that electrons are the subatomic particle that interacts most directly with the EM field like the Higgs boson interacts with the Higgs field however that’s a theoretical MASS giver, not a GRAVITY giver. We don’t have evidence of a graviton yet. We do have evidence of electrons
@Dylan I’m sorry if my comments read in a rude way, I didn’t mean to come across like that at all! I love the topic as well. One of the most fascinating parts of physics.
@I Teragami I’m about to watch that video, I went and found it, thanks for mentioning it!
Veritasium consistently has the best content of any YouTube channel. Thank you again, Derek and team!
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.
When he said “in 25 years we’re gonna look back at now as an inflection period” that hits home. He’s right on the money there, in so many ways.
@b2a1c3d4 Same, I don’t see how this is that revolutionary based on what was presented.
@TBUK AI replacing everyone’s jobs wouldn’t be a bad thing, except in our current system, you need a job to survive. If corporations weren’t hell bent on maximizing profits no matter how much it makes normal people suffer, I wouldn’t be afraid of AI. Decades ago, we dreamed of automation and AI relieving us of our menial labor and boring tasks, allowing us to work on things we truly enjoy. Instead, we got the future where automation and AI (and the companies pushing for them) are stealing away our ability to do things we truly enjoy in favor of making us do all of the menial labor and boring tasks.
@Filip Also, if or when AI gets to the point of replacing the jobs of everyone.
He misspoke. He meant to say a time of infection.😁
I think he was overstating the relevance. Which is not to say that this work is irrelevant. It’s just not as relevant as he would like to believe. The truth is that there are many things that are critical in our ongoing effort to understand matter and material characteristics. None of them more important than others.
I know that pro scientists are interested in sharing their knowledge, but letting Veritasium Dude come in and goof around is a very kind and helpful choice. My students really dig this.
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.
The lab is in a place called Innovation Park that has an open house every year which they just had a month ago. A lot of cool science is getting developed in multiple labs, also tied in with FSU.
It was for science, it’s research technically. Just Veritasium makes learning fun lol.
@Peter Yeah, I figured you might have life going on. And all that stuff being more important to you is beautiful, honestly. And it’s a good sign you can verbalize all that! Wishing well to you!
The only difference between screwing around and science is writing it down

Working in the High Field Magnetic Lab in Grenoble France, I work with a 16T superconducting coil every day, and I’ve also experimented on up to 36T, and I’ve gotta say, there are a lot more things you can have fun with in these sorts of labs. Soon we’ll have a 43T coil here too!
@dementionalpotato Or maybe it’s a Russian/Chinese troll, who wants to undermine the West, by undermining interest in science.
Well, of course that is quite unlikely. But I would not completely rule it out, given how much trolling there is in political topics…
@wfemp _ Dude really believes that it’s that unlikely for some seemingly random person to have a fulfilling and interesting position in stem that they are passionate about. It’s actually extremely sad when you think about it.
@Larik “Law schools were invented in 1900”

@wfemp _ he said to lie somewhere else, because clearly that guy works too hard! I mean, imagine constantly working in such strong fields. A little break wouldn’t hurt. Just people looking out for each other
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.
A fun induced currents demonstration you could also do is to compare a conducting ring to a broken conducting ring, i.e. a ring with a break in it so that it’s not a complete circle any more. The broken ring won’t be able to generate the same eddy currents in it and will be noticeably less resistant to motion.
