About This Product
Oersted's experiment is a standard school demonstration that an electric current produces a magnetic field around a conductor. A freely pivoted magnetic needle is placed close to a current-carrying wire or coil, and it turns away from its rest position when the current flows. Reversing the current reverses the deflection. This apparatus holds the needle inside a vertical frame fitted with socket terminals, so students can connect a supply and watch the effect directly. The Oersted Apparatus can be supplied and exported to buyers in Nicaragua, Malta, Somalia, Gabon and Italy.
