Question

recognizing how magnetic poles interact maglev trains use magnets on the train and guideway to levitate the train off the track. the north pole of the magnets on the train must face the south pole of the magnets on the guideway so they repel. south pole of the magnets on the guideway so they attract. north pole of the magnets on the guideway so they repel. north pole of the magnets on the guideway so they attract.

Explanation:

Opposite magnetic poles attract and like - magnetic poles repel. For a maglev train to levitate, the magnets on the train and guideway must repel each other. So the north pole of the magnets on the train must face the north pole of the magnets on the guideway (or south - to - south) to create a repulsive force for levitation.

Answer:

north pole of the magnets on the guideway so they repel.
