According to a Monday 29 of September, 2025, updated report by IRNA News Agency, in a landmark scientific breakthrough, Chinese researchers have successfully created the world’s most powerful steady magnetic field, using a fully superconducting magnet. The magnet allegedly achieved a strength of 351,000 gauss, surpassing the previous world record of 323,500 gauss.
The milestone was reached by the Institute of Plasma Physics (ASIPP) under the Chinese Academy of Sciences, in collaboration with the Hefei International Applied Superconductivity Center, the Institute of Energy of the Hefei Comprehensive National Science Center, and Tsinghua University.
For comparison, Earth’s magnetic field is around 0.5 gauss — making the new superconducting magnet more than 700,000 times stronger.
According to researchers, this technological feat could have profound implications for a range of advanced scientific and industrial applications. These include nuclear fusion, space-based electromagnetic propulsion, superconducting induction heating, magnetic levitation and high-efficiency power transmission systems. The success is also expected to significantly boost the commercialization of next-generation superconducting technologies.
Liu Fang, a leading researcher at ASIPP, explained the core of the breakthrough: “The device utilizes high-temperature superconducting insert-coil technology combined with low-temperature superconducting magnets.”
These superconducting systems are essential in magnetic confinement fusion research, where powerful magnets are used to create a “magnetic cage” that traps high-temperature plasma—potentially enabling clean and virtually limitless energy.
ASIPP has been at the forefront of fusion research in China and recently made another major advance by fully localizing the development of superconducting materials, devices, and systems, a move that could help the country become more self-reliant in high-tech innovation.
This achievement marks a significant step in China’s ongoing investment in superconductivity and clean energy research, reinforcing its position as a global leader in experimental physics and emerging energy technologies.
