Thing I'm looking at now has about 8K channels of 25K amp current sensors, 200 mega-amps peak.



I wonder what's the biggest peak power pulse on Earth. Rail gun? Plane launcher?

How about a lightning strike?

EMP? short, but fast and loud.

Probably one of the experimental fusion power generators. There have been petawatt lasers for some time:

Rogowski coil, maybe?

At CERN, we have these magnetic horns to catch antiprotons. They are pulsed with 400kA for a microsecond or so.

High altitude nuclear explosions can be used to create very large electromagnetic pulses

The sun is powered by hydrogen fusion, and the Carrington event produced large current pulses at the surface of the earth.

If you are referring to man-made and somewhat reproducible, see

The original motivation was flash x-ray generation for weapons simulation and instrument calibration.

hth,

Electric arc furnace , was the first thing to come to mind.

At tha price point there must be some industry that gobbles them up. Rail maybe?

Cheers
