Japan’s Magnetic Levitation Cars Could Transform the Automotive Industry

The Technology

Magnetic Levitation Explained Maglev technology uses magnetic fields to suspend objects without physical support, eliminating friction for smoother, more efficient movement. While maglev trains in Japan and China utilize this technology, they require constant electrical power to maintain levitation. The OIST researchers’ innovation changes this, significantly reducing the energy needed for propulsion.
