The Future Of Transportation Depends On Magnetic Levitation

The Future Of Transportation Depends On Magnetic Levitation

Magnets are fun to play with, but their potential extends far beyond that. Magnetic levitation (maglev), for example, continues to set records for high-speed travel. The first maglev train began operation in 2004 in Shanghai, and moves up to 267 miles per hour (431 kilometers per hour). For comparison, Amtrak's highest-speed commuter rail only hits 150 mph (241.4 kph).

Maglev means that the train doesn't actually touch the tracks but rather floats above them. The electrically charged magnets repel the train from the tracks to keep the train levitated, and the lack of friction between the train and the track enables the high speeds. By the year 2045, maglev trains are expected to make travel time between Tokyo and Osaka just one hour, about half the time it takes today.
