Magnets in front of the train constantly pull magnets in the train toward them.
Magnets behind the train constantly push magnets in the train forward.

The correct answer is: Magnets in front of the train constantly pull magnets in the train toward them.
To explain how a maglev train moves forward, we need to understand the basic principles behind magnetic levitation. Maglev trains use magnetic forces to levitate and propel themselves forward. They are designed with magnets both on the train itself and on the tracks.
The tracks have a series of electromagnets that generate a magnetic field. These magnets are constantly switched on, creating a repulsive force between the magnets on the train and the magnets on the tracks. This repulsive force allows the train to float above the tracks, eliminating the need for wheels or traditional friction-based propulsion systems.
In order to move forward, additional magnets are placed on the front of the train. These magnets are also constantly switched on to create an attractive force with the magnets on the track. As the magnets on the front of the train are attracted to the magnets on the track, the train is pulled forward.
To maintain a constant speed, the magnets on the track in front of the train are switched off and the magnets behind the train are switched on. This creates a continuous motion as the magnets in front of the train pull it forward, while the magnets behind it push it from behind.
It's important to note that the specific design and functionality of maglev trains can vary, but the general concept involves the use of magnets to create both levitation and forward propulsion.
