Magnetic levitation, also known as maglev, is a transportation technology that uses magnets to lift and move vehicles, such as trains, above the tracks without physical contact. This system works by using powerful magnets to create a force that pushes the vehicle upwards and another force to move it forward. Because there is no friction between the vehicle and the track, maglev trains can travel at very high speeds smoothly and quietly. Magnetic levitation is often used for high-speed trains, offering a fast and efficient mode of transportation.
