The students continued their experiments on force fields, this time investigating magnetism. One group student set up the demonstration you see here. “Oh wow!” Sarah exclaimed. “It’s magic!” Is it magic? Which statement best explains how the center magnet is able to hover between two other magnets?

• the magnets are stacked so that like poles are facing one another

• the opposite poles of each magnet are facing each other so they repel

• the middle magnet is repelling the top magnet while attracting the bottom

• the middle magnet is attracted to the top magnet but pulled down by gravity
