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

    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.

    That guy is multi-classing in real life. He's strong, smart and charismatic
  • 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.
  • Derek probably loved the “you’re strong like bull” compliment at 11:00 for it to make it into the final cut 😂
  • @BlackFragFilms
    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.
  • 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.

    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!

    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
  • @papermarioish
    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 :)
  • You never really forget the ones who touched your heart; regardless whether it's the ones who broke it or the ones who healed it.
  • @troybrumm17
    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.
  • @TheArtifice
    The facility's safety manager watching Derek surf a metal sheet over a huge magnetic hole is watching this like, 'I'm getting fired tomorrow'.

    "You let him do WHAT??!"
  • @RaExpIn
    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!
  • @curvs4me
    The Amps are simply unbelievable. I get the 500v to limit possibility of Arc. With that amperage I can't even imagine the potential hazards.
  • @outandabout259
    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.
  • One thing that's really amazing is that people can be present and act in such strong conditions without any harm. We are very vulnerable to many other influences - light, heat, coldness, sound, radiation, gravitation, etc, but 45T - no, nothing, let's have another beer. Thank you very much for the video! Very interesting! Well, and the magnets are always magic :)
  • 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.
