Anti-clickbait: they didn't blow up their lab, just blew the doors off an iron enclosure intended to contain the massive shockwave, which turned out to be even more massive than intended. Still impressive though!
- SketchySeaBeast 8y ago> just blew the doors off an iron enclosure intended to contain the massive magnetic field Now, I'm by no means a physicists, but aren't iron enclosures particularly bad at containing magnetic fields?
- bitexploder 8y agoIt had a lot of holes, maybe that has something to do with it. Looked like a giant microwave door screen.
- cuboidGoat 8y agoThe magnetic field will tend to concentrate in the iron, meaning it shouldn't propagate as far. Same as using Mu metal for magnetic shielding - https://en.wikipedia.org/wiki/Mu-metal https://en.wikipedia.org/wiki/Mu-metal
- SketchySeaBeast 8y agoIt shouldn't propagate, but the whole thing should be magnetized at that point, right? While you've got that electro magnet on you could probably stick fridge to the big iron magnet you've created with the container?
- cuboidGoat 8y agoDepends on how the field moves relative to the iron. If it expands then contracts, which seems highly likely, the overall effect on magnetizing the iron could be surprisingly low, as far as I am aware. Though I could be wrong on this. edit - ahh, reading through you mean during the experiment, rather than it being left magnetized afterward. During the test it should focus field lines within it. The overall strength of the field will remain the same, but field lines will be concentrated on the cage, meaning it does not propagate as far. Though there should be people on here that will be able to explain this better than I can. And correct me if I am talking rubbish. I am solidly an amateur on this, and there are definitely some professionals floating about.
- empath75 8y agothe iron enclosure was meant to contain the explosion not the field.
- camtarn 8y agoGood point - edited!
- CompelTechnic 8y agoFrom a tiny bit of experience, I know that industrial electromagnets (think of the ones they use to pick up steel at a scrap yard) often have an iron/steel housing that is used as a "return path" for the field. The front face of the magnet has a field that projects out into the air, but the field on the back face gets channeled into the housing.

- contravariant 8y agoWell you're going to need something that reacts to magnetic fields in some way. In that sense iron isn't an odd choice. Anything that isn't susceptible to magnetic fields is not going to do much, even if its conductive that can only help against brief bursts.
