World's Strongest Magnet!

Of course you need the worlds strongest man to control the worlds strongest magnet. Dude’s jacked 😂

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.

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.

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 reflecting also 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 if the small change of the plate temperature is real. It might be an systematic measurement error.

Better use a thermistor or something similar.

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.

Studying for the MCAT while working full time and finishing grad school. I've been using your videos to help see practical application of these crazy physics laws I've learned years ago in undergraduate school in action. And Derek Muller, or better yet Mr. Veritasium, you are inspiring, this content is amazing, and it makes me wanna change the way students learn and absorb this information in.

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.

One thing I like about Veritasium is that he interacts with the people who actually come up with stuff, the troops in the trenches.

I used to work in Innovation Park near there. Before I took that job, I had worked in a machine shop, which resulted in my hands being somewhat full of steel splinters and filings. When I walked past the magnet bays, I could actually hold my hands up and "feel" the contours of the magnetic field. It was pretty cool, but only lasted until the steel in my hands rusted away.

Would love a more specific indepth exploration of that B-coil failure. Immensely interesting! That encompasses the extremes that limit stuff like generators and motors

Another Great video, Versatium! The Magnet Man is truly fascinating, and his explanation of magnetism is mind-blowing. It's amazing to think that they use such a high amount of electricity to generate 45 T of magnetic field. I'm curious to know if there are any health implications for humans working with such strong magnetic fields. Thank you for another fun-filled and learning episode!

Discovering magnetic rocks 3000 years ago must have seriously blown some minds 🤯

The quality of your videos, your joyful character that is enthusiastic about the topics, and notably your transparency when it gets to disclosing sponsorships of videos are remarkable.
Thank you for producing videos on this platform, truly. Nobody is infallible, but you aim to be your best and I respect that so much.

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.

This was simply awesome! I've always heard the stories about floating strawberries or even frogs, but I have never seen footage. Love this channel!

sure I love science, I have always loved it, nonetheless it never gets old, the euphoria, the excitement and the magic, especially when someone like Tim describes it. Thank you Derek, and a huge thanks to Tim (and the whole team of the NHMFL of course), he convinced me to work out, it's even more convincing when a well shaped man, talks science. respect.

I'm studying materials science, first year soon behind, and it's really fun to actually understand what you are talking about! I wish I can do something even partially as cool as this after I'm done with my studies.

That is ridiculously cool. And I love how scientists are basically adults that never lost their childhood curiosity.

I've done research here as a user. I did not get a chance to see the 45T hybrid magnet in action but was able to take some pictures. Actually worked in a lab just a few cells away from it for 4 weeks. This is a very cool video, and I love the science outreach being done here, although it does stress me out to see them playing around the hybrid magnet, especially after all that safety training I had to take before doing research at the NHFML. I actually ended up accidentally demagnetizing my hotel key card a few times working in this lab and annoyed the front desk of my hotel lol. Thanks for the video and Tim is a great guy, him and the administrative office were awesome :)
