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

       | 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.

       | 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.

       | 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?

       | Electronics only work if you keep their smoke inside.

       | 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.
         |

         | 
         | 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.

       | So is something like an EMP ? Shouldn't it cause damage to the
       | surrounding electronic devices ?

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

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