Oersted’s Apparatus

SKU: 0914-1401 Category:


  • Oersted developed a principle that describes the magnetic field around a current- carrying conductor.
  • Oersted principle states that a charge moving through a straight conductor produces a circular magnetic field around the conductor.
  • This instrument shows the action of electric current on a magnet.
  • Instrument is used to show the magnetic field created by the current during experiments.
  • A cobalt-steel needle (75 mm long) with agate bearing supported by a pivot is mounted on a plastic base and surrounded by a rectangular frame fitted with terminals.
  • Setting up a compass through a wire carrying an electric current, Oersted’s apparatus shows that moving electrons can create a magnetic field.
