HFIPS: Resistive Magnet

2024: Product Announcement

At the end of September 2024 ChineseHefei Institute of Physical Sciences (HFIPS) , he set a new record, creating a stable magnetic field of 42 tesla. Thanks to this achievement China , it overtook, USA which held the record for creating the most powerful resistive magnet since 2017.

A resistive magnet is a type of electromagnet made of metal, usually copper or aluminum. Although these electromagnets can create a powerful magnetic field, they also release heat intensively due to the resistance in the conductive coils. To overcome this problem, scientists used superconducting materials that can conduct current without generating heat. However, these magnets can only operate at temperatures close to absolute zero. Unlike superconducting magnets, resistive magnets provide greater flexibility and controllability and create more powerful magnetic fields. A third type of electromagnet, the hybrid magnet, uses both resistive and superconducting magnet technologies to create large magnetic fields.

In 2022, researchers from the Hefei Institute of Physical Sciences of the Chinese Academy of Sciences set a world record for creating a hybrid magnet that provides a magnetic field of 45.22 tesla. Two years later, the team also set a record for resistive magnets. According to a press release, the institute's scientists and engineers have spent the past four years improving the structure of the resistive magnet and optimizing its production, and launched the project on September 22, creating a magnetic field of 42 tesla from 32.3 MW current.

A powerful magnet will help researchers create the conditions for conducting experiments and studying new phenomena and laws of physics. A strong magnetic field is a critical component of materials research and serves as an important tool for new discoveries in physics and medicine.^[1]
