  • A.Paper is magnetic
  • B.The clip is paper
  • C.The pull passes through some materials
5.The steel plate stopped the magnet moving the clip. What does that show?
  • A.The clip was tired
  • B.Magnets stop working near steel
  • C.Some materials block the magnetic pull
6.A rubbed balloon picks up small pieces of paper. What is the cause?
  • A.The balloon is sticky
  • B.An electric charge on the balloon attracts them
  • C.The paper is magnetic
7.A paperclip jumps to a magnet 4 cm away. What does that show?
  • A.Something invisible pushed it
  • B.A magnet can pull without touching
  • C.The clip was already moving
8.A clip does not move at 8 cm but does at 4 cm. What does distance do?
