Question

explain how a maglev train provides evidence that magnetic fields can apply forces between objects that do not touch.

Answer 1

Answer:

Powerful electromagnets are fitted on top of guideways either ttract or repel the magents fitted on the bottom of train. The froce of attraction/repulsion rasies the train in hovering position.

Explanation:

Magentic fields exist between two opposite/like poles. The poles do not have to be touching each other. They can be separated by a distance in a medium that doesn' block magnetic field.

In magelv train the magnetic forces between two poles are used to operate the train. The two poles are separated by train body and air.
