Part A
What is the most important effect of the maglev traln using
electromagnets to move?
A.An electric current flows through the electromagnets and changes which poles are
north and which are south.
B.As the train is moving, if a north pole magnet approaches a south pole magnet,
the magnets attract.
C) The electromagnets are similar to how you can use one magnet to push or pull
another magnet across a table.
D.While moving, a maglev train is not in contact with the ground, so there is no
friction.
