The correct answer is Repellent, magnetic force. Maglev trains use powerful magnets to create a magnetic field that causes the train to levitate above the tracks, eliminating the need for wheels. The magnetic field is created by superconducting magnets on the train and electrical coils on the track, which repel each other, keeping the train hovering above the track. This allows for faster and more efficient travel, as there is less friction and resistance between the train and the track.
A maglev train hovers above the track due to the interaction of attractive and repellent magnetic forces. The train uses powerful magnets and electrical current to achieve levitation and propulsion. These magnets create an attractive force between the train and the track, which allows the train to lift off and "hover" above the track. Additionally, the train also uses repellent magnetic forces to maintain a stable distance from the track. This combination of attractive and repellent forces allows the maglev train to achieve levitation and travel smoothly along the track without any physical contact. Massive batteries are not directly responsible for the train's ability to hover above the track but are used to supply power for the magnets and other systems on board.
