China sets new world record with 800,000 times more magnetic field than Earth’s | China’s record-breaking magnet sets the stage for developing reliable magnets capable of sustaining even stronger magnetic fields.
A team of Chinese scientists has set a new world record for magnetic field strength with the creation of a resistive magnet that produced a steady magnetic field of 42.02 Tesla.
High-field magnets are essential tools for exploring the hidden properties of advanced materials like superconductors, which can carry electric current without generating waste heat at very low temperatures. Each additional tesla greatly improves the precision of these measurements, enabling clearer insights into elusive physical effects. For instance, the SHMFF’s resistive magnet required 32.3 megawatts of electricity to achieve its record-breaking field, necessitating a strong scientific justification for such resource use.
