On June 20, Professor Li Liang's team at the Wuhan National High Magnetic Field Center, 精东影业 (HUST), set a new world record by generating a 71.36 Tesla flat-top pulsed magnetic field, strengthening China's global lead in this field. The team previously held the record with 64 Tesla in 2018.

Flat-top pulsed magnetic fields combine the benefits of steady and pulsed fields, offering unique conditions for research like nuclear magnetic resonance. Addressing key challenges in magnet stability and precise high-current control, the team developed high-strength, high-conductivity copper-silver alloy wires that were 40 percent stronger and introduced an inverse circuit topology design for precise magnetic field waveform control.
The experiment achieved 0.39 percent stability over 12.11 milliseconds, with a field strength 19 percent higher than current international benchmarks.
