Sarah is looking for a way to move her boat across the water without touching it directly. She included paperclips in the boat design so that the magnetic attraction between the paperclip and the magnet would pull the boat along the water's surface. Which statement is NOT an accurate representation of what is happening with Sarah's boat? A) The attraction between the boat and the magnet pulls the boat toward the magnet. B) As Sarah gets further from the boat with her magnet, the attraction will decrease. C) The attraction between the boat and the magnet pushes the boat away from the magnet.
