China produces magnets 200,000 times stronger than Earth

Superconducting magnets can help create the correct medical devices for the nerve.

Scientists at the High Magnetic Field Laboratory of the Chinese Academy of Sciences in Hefei have developed superconducting magnets capable of producing up to 10 Tesla magnetic fields, which are 200,000 times more powerful than Earth's.

It has an inside diameter of 92cm. Meanwhile, superconducting magnets are located at the American National High School Laboratory in the state of Florida with a diameter of only 2.5 centimeters and produce 3 Tesla fields. It is difficult to create and maintain a high and stable magnetic field in large spaces.

"We have caught up with the United States and other developed nations in building the world's most modern magnets , " said Gao Bingjun, a professor of Chinese studies. "We hope to surpass them in the next few years."

The world's largest continuous-magnet school record is 45 Tesla, created in the state of Florida in the United States. But Gao says the record will soon be over because their goal is to create a strong magnetic field of up to 60 Tesla.

Superconducting magnets play an important role in scientific research. Researchers have discovered unknown physical properties by examining materials in high magnetic fields, thereby creating many applications such as miniaturization of electronic devices.

Strong magnetic fields will also help physicists have stronger tools to find materials suitable for quantum computers or superconducting materials at high temperatures, allowing the ship to outperform the sound.

Another important application of magnetic fields is MRI imaging in hospitals. 10 Tesla MRIs are not harmful to the body and can produce a clear image of a small area of one-tenth of a millimeter, enough for scientists to test for nerve or cardiovascular activity. .

The problem for Chinese scientists today is that their superconducting magnets do not sustain continuous magnetic fields and lose energy rapidly.
