This blew my mind… some bullet trains don’t even touch the tracks? They actually hover… no wheels, no friction. But how can something that heavy float at all?
They use something called magnetic levitation, or maglev. Powerful magnets in the track repel magnets on the train, lifting it a few centimeters off the ground. But here’s the real question: once you’re floating, how do you actually move forward?
That’s where another set of magnets comes in. Instead of just repelling, they’re arranged to pull the train forward. Imagine a magnetic wave racing down the track, the train is basically surfing that wave. Pretty wild, right?
But if there’s almost no friction slowing it down… just how fast do you think it can go?
The fastest test train in Japan hit over 600 km/h. That’s faster than a jet taking off, yet smooth enough for passengers to sip coffee without spilling. So is this the future of travel…?
