A team at the University of Tokyo led by Shojiro Takeyama generated a magnetic field of 1,200 tesla in April 2018 using an electromagnetic flux-compression technique that destroys the coil in the process — the strongest magnetic field ever created in a laboratory, lasting about 40 microseconds. Non-destructive (reusable) magnets top out far lower, around 100 tesla for pulsed fields and under 50 tesla for continuous fields.

The highest magnetic field strength ever generated in a laboratory, by any method (including destructive, single-shot techniques).
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
