The New Superconducting Magnet of 35.6 Tesla Developed by the Chinese Academy of Sciences, Installed in a Recently Approved National Infrastructure in Beijing, Surpasses Previous Laboratory Records, Expands International Access to Extreme Magnetic Fields, and Consolidates Technical Advancements in High-Temperature Superconductors for Large-Scale Scientific Research

Researchers in China have achieved 35.6 tesla in a laboratory superconducting magnet, in Beijing, a result announced on Tuesday by the Chinese Academy of Sciences, expanding experimental capabilities, international access, and studies under extreme magnetic fields with prolonged stability.

New World Record in Superconducting Magnetic Field

The central magnetic field of 35.6 tesla was obtained in a national experimental facility in Beijing, establishing an unprecedented global milestone for laboratory-use superconducting magnets. This achievement positions China among the leaders in high-temperature superconducting technology.

The experiment took place at the Synergetic Extreme Condition User Facility, a platform designed to host scientists from China and abroad. The result expands access to magnetic fields far beyond those available in conventional laboratories.

Fully Superconducting System and Open Research

The new magnet is a completely superconducting system, relying on superconducting materials to generate intense fields with minimal energy loss. The useful diameter of 35 millimeters allows for direct experimentation in the field.

Designed as a shared research tool, the equipment is already available for national and international users. The declared goal is to support cutting-edge experiments in materials science, life sciences, and other areas dependent on strong and stable fields.

This level of performance is essential for investigating material behaviors under extreme conditions that cannot be replicated by other means. Open access broadens the scientific use of the system across different disciplines.

Institutional Cooperation and Engineering Advancements

The development resulted from cooperation among agencies linked to the Academy.

The Institute of Electrical Engineering led the project, the manufacturing and integration of the superconducting magnet system.

In parallel, the Institute of Physics focused on the challenges of monitoring system integrity and on accurate measurement of high-temperature superconducting components, ensuring operational reliability.

Previous versions achieved lower levels in 2023. Since then, materials have been improved, the structural design optimized, and manufacturing processes refined, elevating performance without reducing the bore diameter, an essential requirement for users.

These improvements consolidate advanced international capabilities in the application of high-temperature superconductors in large-scale scientific instruments, according to the institutional assessment released.

Operational Stability and Demanding Measurements

Beyond field strength, the value for users lies in stability and reliability. Superconducting systems operate at extremely low temperatures, where electrical resistance drops to zero, allowing for uniform fields over long periods with reduced consumption.

According to Luo Jianlin, a researcher at the Institute of Physics of the Chinese Academy of Sciences, the system can maintain the maximum field stably for over 200 hours and integrate into extreme conditions, such as ultra-low temperatures and high pressures, according to a report from Global Times.

This stability enables measurements such as nuclear magnetic resonance, specific heat, and magnetostriction, widely meeting the needs of the scientific community, according to the statement. Sustained performance is central to complex and repeatable experiments.

National Infrastructure and Scientific Impact

The magnet is installed in the extreme conditions research complex in the Huairou Science City, on the outskirts of Beijing. The infrastructure was approved by the national government in February 2025.

The complex combines ultra-low temperatures, intense magnetic fields, ultra-high pressure, and ultrafast optical systems in one location. The joint operation broadens the scope of possible research in an integrated environment.

With other platforms at the site, the new magnet will support explorations of the microscopic world of matter and accelerate discoveries related to advanced instruments, medical technologies, energy systems, and transportation.

Strong magnetic fields are important tools for studying materials, including high-temperature superconductors and quantum materials. They also contribute to precise biomolecular analyses and the development of medical technologies, such as targeted magnetic therapy, according to Luo, reinforcing the global impact of the equipment.

Libya built over 4,000 kilometers of underground pipelines to bring water from the Sahara to coastal cities in a project that the government itself called the Eighth Wonder of the World.

Desert sand, previously discarded for being too smooth for concrete, becomes an ecological brick in the United Arab Emirates, dispensing with Portland cement, curing at room temperature, and attempting to transform dunes useless for construction into raw material for a new arid engineering.

China transforms desert-devastated area into the world’s largest artificial forest, planting trees for 60 years, blocking sand that reached Beijing, and creating a “green lung” of 92,000 hectares in a region once considered lost.

Toyota launches “family hybrid van” with 7 or 8 seats, 1.8 hybrid engine, fuel consumption of up to 23.8 km/l, and a price equivalent to about R$ 104,000 without taxes, below the Tiggo 8 Pro Plug-in Hybrid sold in Brazil: meet the Noah Hybrid 2026 in Japan.

Chinese woman planted trees for decades while sand buried part of her house, received $5,000 from an American in 1999, and helped transform the desert into a forest of 8 million trees in China.

Change in INSS reduces waiting time from 45 to 30 days, prioritizes pensions, revisions, and BPC, and could expedite over 100,000 stalled processes, while employees receive productivity bonuses and the government attempts to reduce a backlog that still exceeds 2.1 million requests.

They wanted artificial intelligence, but they drained the water from a village in Mexico: the water consumption of data centers caused a hepatitis outbreak, and big tech companies Amazon, Microsoft, and Google were forced to halt billion-dollar projects.
