  • Describe the pattern and direction of the magnetic field of a bar magnet
  • Visualise the shape of magnetic fields using iron filings or magnetic compasses
  • Predict the behavior of magnets when they are brought in close proximity
  • Compare the magnetic field of the Earth to that of a bar magnet
  • Distinguish between the geographic and magnetic poles of the Earth
  • Give examples of phenomena relating to the magnetic field of the Earth
  • Discuss qualitatively how the magnetosphere provides protection to the planet
