  • A carbon rod aligns itself with the magnetic field.
  • Poles should be ~5 cm apart.
  • A video camera may be needed in a large classroom
  • CAUTION: keep magnets at least 30 cm away from ALL other ferromagnetic materials.


  • A glass rod turns perpendicular to the magnetic field.
  • Poles should be ~2.5 cm apart.
