China's breakthrough: a new record of magnetic field exceeds the Earth's by 700 thousand times<\/h2>\n

Chinese scientists have announced a record-breaking result in the field of plasma physics: researchers from the Institute of Plasma Physics of the Chinese Academy of Sciences (ASIPP) have generated a constant magnetic field with a voltage of 35.1 tesla (T)<\/strong>, which is ~700,000 times stronger than the Earth's magnetic field (approximately 0.00005 T).<\/p>\n

This record not only surpasses the previous best of 32.35 Tl, but also demonstrates China's significant progress in developing modern superconducting technologies.<\/p>\n

\n

How we did it<\/h3>\n

The researchers used complex superconducting structures: they used high temperature superconducting insert coils<\/strong> together with low-temperature superconductors. This made it possible to maintain the stability of the magnet in extreme conditions - without loss of performance.<\/p>\n

They faced technical challenges: the effects of shielding currents, multipole connections in complex circuits, and the issue of voltage and pressure concentration in a low-temperature environment. But the new design proved stable enough to operate for 30 minutes at full load.<\/p>\n

After the test, the magnet was demagnetised, which confirmed the reliability of the method.<\/p>\n

\n

What it means: potential applications<\/h3>\n

The achievement has important prospects for scientific and applied technologies:<\/p>\n

    \n
  • \n

    Promotes the development of superconducting devices - in particular for nuclear magnetic resonance (NMR)<\/strong>, used in medical imaging and chemical analysis.<\/p>\n<\/li>\n

  • \n

    Helps to create effective magnetic deposits for fusion<\/strong>, where strong fields are required to retain the plasma.<\/p>\n<\/li>\n

  • \n

    Can be used in electromagnetic launch, magnetic levitation (maglev)<\/strong>, The company's expertise includes superconducting induction heating and energy transmission systems.<\/p>\n<\/li>\n

  • \n

    Makes China less dependent on imports of critical superconducting materials.<\/p>\n<\/li>\n<\/ul>\n

    \n

    Context and meaning<\/h3>\n

    The ASIPP Institute has long been cooperating with international projects, including ITER (International Thermonuclear Experimental Reactor). China is now localising the production of key components: superconductors, coils and power magnets.<\/p>\n

    This technological independence is of strategic importance: in the global competition for future energy sources, magnetic technology is becoming one of the key factors.<\/p>","protected":false},"excerpt":{"rendered":"
