They let the smoke out. You aren't supposed to do that. Electronics only work if you keep their smoke inside.

Just trying to figure out what kind of smoke is in an atom.
dexwiz
Subatomic smoke, also known as quantum smoke. It's both here and there, but you will never know until you look.

You know you've done something pretty cool when your equipment catches fire after the experiment is complete.

Either that or you've made a mistake somewhere. :D

I can assure you that there’s a way to do nothing cool and still have things catching fire. Don’t ask me how I know, the school made me sign a lot of papers after the incident.

Youtube says the video was posted 4 days ago, but some comments are 4 years old?

Although under the description it says 'First Published: 25 Sep 2018'.

You can share a video privately, and later open it for anyone to see. Comments from people who were able to see it would appear like that.

that ten second video played in a web browser and IMMEDIATELY jumped to an ad-filled marketing one. The YouTube experience is visibly deteriorating

Details, anyone? What kind of current are we talking about? How long did the field last? Was anything interesting placed in the field, and did something interesting happen to it?

I'd love to see Someone familiar with high magnetic fields answer this: what exactly is going on and why did it blow up?

My guess(reading the article now) is that it is an explosively formed magnetic field. that is, the explosion is part of the process.

For EM fields(same thing?) you can build a flux compression generator, a coil of wire around an explosive rod. run a current in the wire to form a magnetic field, as the explosive explodes from one end to the other the field compresses to form a high energy pulse.

https://en.wikipedia.org/wiki/Explosively_pumped_flux_compre...

edit: As best I understand, it is similar to an explosively formed field but uses one magnet to compress the other. the explosion was halfway expected, the compressed magnet was expected to tear itself apart, however the field was higher than expected and damaged the enclosure.

Interesting - initially, I bought that the explosion might have been caused by the magnetic field, like an arc, not the other way around.

Just looks like an explosion to me. Whats the point?

I was disappointed that this wasn't the release of a new record by The Magnetic Fields.

1200 is a lot. Did they say which model of Tesla it was?

I wanted to look up some context for this record.

The record for a man-made stable (not explosive) magnetic fields is 45T.

The record for detected cosmic magnetic fields is 1,600,000,000T.

This is the first time I used the 0.25x playback speed setting on Youtube.

So is something like an EMP ? Shouldn't it cause damage to the surrounding electronic devices ?
nullc
Flux compressors-- it's an EMP weapon.

I'll repeat the words my friend told his buddy when a 4 inch arc came out of, and sustained itself, buzzing away at 120 Hertz, from the internals of an RF amplifier.

  I don't think it's supposed to do that. ;-)
