Used for demonstration on Newton's colour disc experiment.
Demonstrate: the physics experiment with a rotating disc with segments in different colors (usually Newton's primary colors: red, orange, yellow, green, blue, indigo, and violet) appearing as white (or off-white or gray) when it spins very fast.
This Newton's Disc consists of an aluminium plate with coloured segments printed on it.
The colours represent the colours of the visible spectrum (red, orange, yellow, green, blue, indigo and violet)
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.
