China Completes Testing of World’s Largest Fusion Magnet

Exam-focused facts from the 30 July 2026 current affairs briefing.

Key facts

China completed testing of the world's largest superconducting fusion magnet, a key component for nuclear fusion energy.
The magnet was developed by the Institute of Plasma Physics under the Chinese Academy of Sciences.
It measures 21 metres long, 12 metres wide, and weighs 582 tonnes.
The magnet has 1.3 times the volume and three times the stored energy of magnets built for the International Thermonuclear Experimental Reactor (ITER).
It is designed to create a magnetic field to confine plasma at temperatures exceeding 100 million degrees Celsius.
The technology was developed entirely using domestic materials, ending China's reliance on foreign supplies for critical fusion components.
China aims to produce electricity from fusion power by around 2030.
