Knowledge Is Power on Instagram: "Trains floating above tracks sound impossible, yet physics quietly makes it real 🚄✨ Magnetic levitation, or maglev, works by removing one enemy of speed: friction. Instead of wheels touching rails, powerful magnets lift the train slightly above the track. With no physical contact, there is almost no mechanical resistance, meaning far less energy is wasted as heat, noise, or vibration. What remains is mostly air resistance, which engineers carefully manage using
