Question

how do electromagnets cause a maglev train to levitate above the track? (1 point) batteries provide electric energy to the electromagnets in the train. magnets in the track and magnets in the bottom of the train attract each other. magnets in the track and magnets in the bottom of the train repel each other. magnets in the sides of the tracks constantly repel and attract magnets in the sides of the train.

Explanation:

To determine how electromagnets cause a maglev train to levitate, we analyze each option:

• The first option explains energy supply to electromagnets, not levitation mechanism.
• Attraction (second option) would pull the train down, not levitate it.
• Levitation requires a force that pushes the train up. Like - pole repulsion between magnets in the track and the train's bottom (third option) provides this upward force.
• The fourth option describes propulsion (movement) via side - magnets, not levitation.

Answer:

C. Magnets in the track and magnets in the bottom of the train repel each other.
