The correct answer is: Magnets in the sides of the tracks constantly repel and attract magnets in the sides of the train.
To explain further, maglev (magnetic levitation) trains use magnets to levitate above the tracks and propel forward. The tracks have a series of magnets embedded in them, and the train itself also has magnets on its sides. In a maglev system, the magnets on the tracks are electromagnets, which means they can be turned on and off by electricity.
When the train needs to move forward, the magnets on the tracks ahead of the train are turned on, creating a magnetic field. The magnets on the train's sides are attracted to the magnets on the tracks, causing the train to move forward. As the train progresses, the magnets behind it are turned on, pushing the magnets on the train forward and propelling it even further.
By constantly switching the magnets on and off and effectively repelling and attracting the magnets on the train, the maglev train is able to move forward. The absence of physical contact between the train and the tracks allows for reduced friction and smoother, quieter travel.
