For comparison, Earth itself acts as a giant magnet but generates a geomagnetic field of only about 0.5 gauss. That means the newly achieved field is more than 700,000 times stronger than Earth’s natural magnetic field

Chinese researchers have reached a new milestone in superconducting technology. On Sunday, they announced the successful generation of a steady magnetic field of 351,000 gauss using a fully superconducting magnet. This breaks the previous world record of 323,500 gauss.

For comparison, Earth itself acts as a giant magnet but generates a geomagnetic field of only about 0.5 gauss. That means the newly achieved field is more than 700,000 times stronger than Earth’s natural magnetic field.


This development will help accelerate the commercialisation of advanced superconducting scientific instruments. One key example is nuclear magnetic resonance spectrometers, widely used in fields such as medical imaging and chemical analysis. Beyond that, the magnet offers crucial technical support for several cutting-edge areas like fusion magnet systems, space electromagnetic propulsion, superconducting induction heating, and magnetic levitation.
