Oersted Apparatus
Product Code : JA-EE-7645
The Oersted Apparatus (product code JA-EE-7645) demonstrates the action of an electric current on a magnet, the discovery that first linked electricity and magnetism. In this Oersted apparatus a 75 mm cobalt steel needle turns on an agate bearing supported by a pivot on a plastic base, inside a 130 x 50 mm rectangular frame set in the vertical plane. When current flows round the frame, the needle swings, showing the magnetic field produced by the current.
Specifications
The needle is 75 mm long, made of cobalt steel and mounted on an agate bearing. The surrounding frame measures 130 x 50 mm, stands vertically and carries two 4 mm socket terminals at one end and one at the other.

Applications of the oersted apparatus
The apparatus is used when magnetism due to current is introduced, so students can see the needle respond to a current and reverse when the current reverses.
- Showing the magnetic effect of an electric current
- Reversing the current to reverse the needle deflection
- Relating deflection to the size of the current
- Introducing the right-hand grip rule in secondary physics
