  7. What happens when an induced magnet is removed from a magnetic field?

    • Retains magnetism forever
    • Melts instantly
    • Becomes negatively charged
    • Loses magnetism quickly
  8. What happens when a permanent magnet is removed from a magnetic field?

    • Loses its magnetism

  10. Two north poles of bar magnets are brought close together. They will:

    • Stick permanently
    • Stay still regardless
    • Attract
    • Repel
  11. What happens when an unmagnetised paperclip touches a strong magnet?

    • Conducts electricity
    • Becomes induced magnet
    • Loses all mass
    • Emits gamma rays
  12. Why does a steel nail fall off a magnet when moved far away?

    • Gains permanent charge
    • Reverses its poles
    • Melts from friction
    • Loses induced magnetism
  13. Which combination of magnetic poles will attract each other?

    • Like poles
