Chinese researchers announced on Sunday that they have generated a stable magnetic field of 351,000 gauss using a fully superconducting magnet, setting a new world record.
The breakthrough, achieved at the Institute of Plasma Physics of the Chinese Academy of Sciences (ASIPP) in Hefei, in cooperation with several national research centers and Tsinghua University, surpasses the previous record of 323,500 gauss and represents an intensity more than 700,000 times greater than that of Earth’s magnetic field (about 0.5 gauss).
According to the researchers, this technological breakthrough could have major implications for advanced sectors such as nuclear fusion, electromagnetic propulsion systems for space, magnetic levitation, high-efficiency energy transmission, and nuclear magnetic resonance spectrometers.
The device relies on an innovative hybrid technology that combines high-temperature and low-temperature superconducting coils.
During the experiment, the magnet reached 351,000 gauss, operated stably for half an hour, and was safely demagnetized, confirming the robustness of the approach.
ASIPP, which plays a central role in China’s fusion research program and contributes to the International Thermonuclear Experimental Reactor (ITER) project, also stated that it has achieved complete self-sufficiency in superconducting materials and systems.
