On September 22, 2024, a team of scientists in China made history in the field of magnetic technology by setting a world record with a resistive magnet of 42 constant teslas in its magnetic field.
Breakthrough after years of work on the 42-tesla resistive magnet
This achievement was made at the High Magnetic Field Laboratory of the Hefei Institutes of Physical Sciences(CHMFL), part of the Chinese Academy of Sciences. The new record beats the previous record of 41.4 teslas, set by the U.S. National High Magnetic Field Laboratory in 2017.
The resistive magnetis one of the most advanced tools in the field of scientific research, providing an“extremely high magnetic field“, opening up new possibilities for the study of materials and physical phenomena.
This achievement is the result of nearly four years of research and development, during which CHMFL scientists worked on improving the magnet’s structure and optimizing its manufacturing process. With a 32.3 MW power supply, the team succeeded in generating the strongest magnetic field to date in a resistive magnet.
What is a resistive magnet?
Resistive magnets, in contrast to superconducting superconductorsResistive magnets, unlike superconductors, allow a “more flexible and faster control of the magnetic field”, which translates into the study of a great essential tool, applied in future scientific experiments.
The importance of this breakthrough lies in its usefulness for scientific research. High magnetic fields, such as those generated by this magnet, are vital for the study of advanced materials, nanotechnology and quantum physics. For decades, experiments in extreme magnetic fields have led to important discoveries, some of which have been awarded Nobel prizes.
CHMFL academic director KUANG Guangli noted that this breakthrough puts China in a leading position in resistive magnet research.“The development of this technology is important to maintain China’s scientific leadership, and this achievement is just the beginning,” Kuang commented.
The development of magnetic technology is a field of research of great importance worldwide, with only five laboratories in the world dedicated to the creation of high and stable magnetic fields, located in China, the United States, France, Japan and the Netherlands.

The new resistive magnet meets the team’s expectations, being the “strongest magnet in the world” at present. This milestone lays the foundation for the construction of even more powerful magnets in the future, opening new frontiers for scientific and technological research in the magnetic field.
