I remembered that in 2018 Japanese team manage 1200 T peak power. http://www.sci-news.com/physics/strongest-magnetic-field-ach...

In comparison, 20T does not look much, but again it is, I wonder with the Japanese technique what is the highest continuous magnetic field.

These high magnetic fields are generated using flux compression[0], in which the incompressibility of magnetic field lines means that compressing the coils generating the magnetic fields will increase the strength of the resultant magnetic field. However, the implosion process permanently destroys the magnet, which makes it highly unsuitable for continuous use and certainly shouldn't be used anywhere near your fusion reactor.

1200 T has a magnetic pressure of about 5.7 megabars (about 20x the detonation pressure of high explosives). Such high fields can only be achieved very briefly in devices that explosively disassemble.
