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

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

| 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.

|
| 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.

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

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

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