Question

 Maglev trains, like the one shown in the picture, use magnet fields to travel up to 600 miles per hour. Magnets on the bottom of the train and on the tops of the rails have similar magnetic poles. Based on properties of magnets, how do these magnets affect the train?
A)The two magnetic fields repel each other, causing the train to levitate, or hover, above the rails.

B)The powerful magnets greatly reduce the force of gravity, resulting in less friction and greater speed.

C)The train is able to stop immediately because the magnets on the rails attract the magnets on the train.

D)Maglev trains have extremely powerful magnets, greatly decreasing the force of gravity and allowing them to float.

Answer 1

The correct answer is A) The two magnetic fields repel each other, causing the train to levitate, or hover, above the rails.
In fact, same magnetic poles repel each other, while opposite magnetic poles attract each other. the magnets on bottom of the train and on top of the railway have the same polarities, so they repel each other and this allows the train to levitate.
