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.
The disposable dish is radiation sterile, non-vented.
Dishes have elevated lid which allows for good gas exchange and encourage
The design of the dish maintains sterility because the particles of gas would have to go up and over the dish wall to get inside which is very rare in normal
