China just completed the world’s largest superconducting magnet built for a fusion reactor. Why is that a big deal? Because fusion reactors need incredibly powerful magnets to confine plasma heated to more than 100 million°C. The stronger and more capable those magnets become, the closer researchers can get to making fusion energy practical at scale.
