By creating a 42-tesla resistive magnet, China has broken the US record set in 2017 and accomplished a new milestone. China’s creation of a potent 42-tesla resistive magnet has raised the bar globally. The nation has surpassed the 41.4-tesla record that the US had held since 2017. The Chinese Academy of Sciences-affiliated Hefei Institutes of Physical Science’s High Magnetic Field Laboratory made the breakthrough on September 22. Following years of research and structural improvements, this breakthrough in magnetic field technology places China at the forefront of high-field magnet science and offers new tools for scientific and material research.
A Significant Advancement in Magnetism Technology
The 42-tesla resistive magnet, which is powered by a 32.3 MW source, is evidence of China’s engineering prowess in this area. The Hefei lab’s accomplishment comes after they achieved 45.22 teslas in 2022 with the strongest hybrid magnet in the world. The innovation is the result of production and structural improvements over almost four years of consistent work. The end product was a magnet that could sustain a powerful, constant magnetic field. This enables a range of scientific applications that rely on high magnetic fields for research and discovery.
Providing Assistance for Advanced Scientific Research
The new resistive magnet provides an advanced tool for scientific investigations, enabling researchers to explore materials and phenomena at extreme magnetic fields. According to Guanli Kaung, academic director at CHMFL, magnetic fields of this strength are essential for investigating fundamental properties of materials, often leading to discoveries in physics and chemistry that have real-world applications. Researchers can explore issues of material behaviour and atomic interaction with the help of high-field magnets.
China’s Role in International High Magnetic Field Studies
China now has specialised high-magnetic-field research labs, joining five other countries—the US, France, Japan, and the Netherlands. The field continues to be a focus of cutting-edge scientific research, with multiple Nobel Prize-winning discoveries arising from studies conducted in extremely magnetic environments. China’s recent performance demonstrates its dedication to advancing magnetic science and sets a high standard for future advancements in the field.
