## TL;DR

This paper demonstrates a method to generate ultra-high magnetic fields exceeding 763 T, approaching 1000 T, using electro-magnetic flux compression and magneto-optical measurement techniques, overcoming previous measurement limitations.

## Contribution

It introduces a magneto-optical Faraday rotation method for measuring extremely high magnetic fields, enabling detection beyond dielectric breakdown limits of traditional coils.

## Key findings

- Maximum magnetic field over 763 T was achieved.
- Reduced seed magnetic field increases the maximum field.
- Potential to reach up to 985 T approaching 1000 T.

## Abstract

An ultra-high magnetic field was generated by the electro-magnetic flux compression technique under a reduced seed magnetic field condition and achieved maximum magnetic field intensity was investigated. An ordinal pickup coil measurement fails due to the dielectric breakdown at around 500 T. On the other hand, by utilizing the magneto-optical Faraday rotation method with a small probe, the measureable maximum magnetic field increased significantly. It was found that reduced seed field increases the maximum magnetic field, but with a reduced size of the final bore. A highest magnetic field over 763 T and possibly up to 985 T approaching 1000 T was detected.
