Question: What is the standard way to measure a current of about 10,000 A? DC clamp meters seem to have only scales up to 2,000 A.

**Edit**

Some background of this question: 

I am a high school physics teacher and I am trying to improve some classical experiments using high currents from ultra-capacitor discharge. 

In particular I am looking for a good way to measure the discharge current of a ultra capacitor for very short times like in this "jumping ring" experiment:

[A safe and effective modification of Thomson’s jumping ring experiment](http://www.rose-hulman.edu/~moloney/Ph425/0143-0807_33_6_1625JumpingRing.pdf)

The second motivation for this question was just because I just want to know it out of curiosity for my background knowledge of what is the usual way to measure such high currents today.

Answer: 
If there is a way to run the experiment setup at a lower current temporarily, one could pick any two exposed spots on any conductor in the setup, attach a voltmeter, calibrate with a known current, and use that length of conductor as an intrinsic shunt.
My suggestion would be to either measure the displacement of the ring/the force, and work back to the current. 

Or you could just build one beauty of an electromagnet...and measure it's field from the other side of your classroom...
