The 20 questions

  1. Where are the magnetic forces of a magnet strongest?

    • Along its midline
    • At its poles
    • Equally everywhere
    • At its centre
  2. What force is observed when two like magnetic poles are brought close together?

    • Attraction
    • Gravity
    • Friction
    • Repulsion
  3. Why do two north poles of bar magnets push apart when brought together?

    • Like poles repel
    • Induced magnetism
    • Unlike poles attract
    • Magnetic saturation
  4. What kind of force acts between two magnets that are not touching?

    • A contact force
    • A frictional force
    • A non-contact force
    • A nuclear force
  5. What does a permanent magnet always produce around itself?

    • Gravitational field
    • Magnetic field
    • Electric field
    • Sound wave
  6. What term describes a material that becomes magnetic when placed in a field?

    • Electromagnet
    • Insulator
    • Induced magnet
    • Permanent magnet
  7. What kind of force does induced magnetism always cause?

    • A force of repulsion
    • No force
    • A force of attraction
    • Heating
  8. What happens to an induced magnet when removed from a magnetic field?

    • Loses magnetism quickly
    • Retains all magnetism
    • Becomes permanently charged
    • Reverses its poles
  9. Which material can become an induced magnet, and so be attracted to a magnet?

    • An iron paperclip
    • A plastic ruler
    • A sheet of paper
    • A wooden block
  10. Why does a second paperclip hang from a first suspended from a magnet?

    • Electrostatic attraction
    • Induced magnetism
    • Gravitational force
    • Permanent magnetisation
  11. What is a key feature unique to a permanent magnet?

    • Loses magnetism quickly
    • Requires an electric current
    • Only attracts iron
    • Retains own field
  12. What force occurs when a north pole and a south pole are brought close?

    • No force
    • Attraction
    • Repulsion
    • Rotation
  13. Two north poles are brought close together. What happens?

    • They attract
    • They fuse
    • Neither
    • They repel
  14. Why can a permanent magnet pick up an unmagnetised iron nail?

    • Induced attraction
    • Frictional grip
    • Gravitational pull
    • Electrostatic charging
  15. A student tests several objects with a magnet. Which is most likely to be attracted?

    • A glass marble
    • An iron filing
    • A wooden peg
    • A plastic counter
  16. What poles does each piece have when a bar magnet is cut in half?

    • Two north poles
    • North and south
    • Two south poles
    • No magnetic poles
  17. What happens when two south poles are brought close together?

    • They cancel out
    • Nothing happens
    • They repel
    • They attract
  18. Which item acts as an induced magnet when placed near a bar magnet?

    • Iron nail on magnet
    • Wooden block
    • Plastic ruler
    • Copper coin
  19. What type of force acts between two separated magnets?

    • Non-contact force
    • Frictional force
    • Contact force
    • Tension force
  20. A student says a bar magnet loses its magnetism when it is removed from a magnetic field. What type of magnet is it?

    • Induced
    • Fixed
    • Permanent
    • Electromagnet
