Earths electromagnetic field shields our world from cosmic radiation and charged particles from our Sun.
China has set a brand-new world record for the strongest steady electromagnetic field.
On August 12, the hybrid magnet of the Steady High Magnetic Field Facility (SHMFF) in Hefei, China, created the worlds highest consistent magnetic field by a working magnet measuring 45.22 teslas (T). In comparison, Earths electromagnetic field at 0 ° latitude and 0 ° longitude only has a strength of 0.000032 teslas.
It surpassed the 45-tesla prior world record set by a hybrid magnet in 1999 at the National High Magnetic Field Laboratory of the United States.

This 45.22-tesla hybrid magnet consists of a resistive insert embedded within a superconducting outsert with a bore of 32mm.

In spite of facing many obstacles, the group successfully built the hybrid magnet in 2016, which produced a central magnetic field of 40 teslas at the time, making it the second 40-tesla level magnet worldwide.
Seemingly, 40 teslas was not completion. The group has actually given that continued its pursuit of more powerful magnetic fields.

” To achieve a greater magnetic field, we innovated the structure of the magnet, and developed brand-new products,” said Professor KUANG Guangli, the academic director of the High Magnetic Field Laboratory of Hefei Institutes of Physical Science, Chinese Academy of Sciences (CHMFL) where SHMFF is based. “The production process of the bitter discs was likewise enhanced,” added KUANG in a statement made on an on-site verification by seven academicians.
The success of the 45.22-tesla magnet represents an important turning point in the advancement of magnetic innovation in China and the world.

The Hefei laboratory has currently broken three world records with its resistive magnets.
SHMFF, a user facility, which currently offers researchers worldwide with the strongest steady-state electromagnetic field, has operated for more than 500,000 maker hours considering that its operation, providing over 170 institutes or universities in your home and abroad with experimental conditions for cutting-edge research of multi-disciplines.
