An ultrahigh-speed test device for electromagnetic propulsion – the "electromagnetic sled" – was successfully operated in Jinan, Shandong province.

The device can propel an object weighing one metric ton or above at a speed of 1,030 kilometers per hour, which sets the world's highest speed record for high-mass ultrahigh-speed electromagnetic propulsion technology.

该设备对于吨级及以上物体最高推进速度可达每小时1030公里，创造了大质量超高速电磁推进技术的世界最高速度纪录。

The device is jointly developed by the Chinese Academy of Sciences, the Jinan municipal government and the Shandong provincial government.

The "electromagnetic sled" has advantages that include large thrust, fast response, precision and controllability. It can be used as a testing method in the R&D of transportation vehicles, satellites and aircraft, experts said.

The device is able to provide testing services to relevant domestic enterprises and research units, which is of great significance to support the sustained and rapid development of China's high-mass high-speed advanced equipment and high-speed scientific and technological research.
