Chladni Plates
The Chladni Plates Kit allows the continuous vibrations to be produced at measurable frequencies to determine the resonant frequencies of the plates and examine the modes of vibration at any frequency. A thin layer of sand is spread over the plate. The sand collected along the nodal lines of the wave patterns painted clear and beautiful pictures of the various modes of vibration. The plate’s resonances are audible. Kit is made of metal sheet in two shapes: square and round. The round plate can be vibrated about its center or an offset point to investigate both symmetric and asymmetric modes of vibration.

Ring Launcher
The ring launcher consists of a vertically mounted solenoid of thick copper wire with an iron core. The coil is energized with by pressing the push button on the panel. Two aluminum rings are supplied with the apparatus. These rings fit over the solenoid and are supported at some height above the base by an adjustable collar. The behaviour of the rings when the coil is energized depends on the type of the ring placed over the coil at the time. The solid aluminum ring is propelled straight up while the slotted ring remains static, thus demonstrating the principle of electromagnetic induction as well as Lenz law.

Force Between Conductors Demonstrator
An easy and safe way to demonstrate the magnetic force between two current carrying parallel conductors. A cylindrical base, containing a dedicated power supply, supports a rectangular frame. Attached inside the frame are two parallel heavy duty metal tubes supported by fine cone bearings which also supply current to the tubes. The directions of the currents in the tubes can be selected, and movable metal arrows on the frame uprights indicate the current direction in each tube. A push button applies a large current at low voltage to the tubes, which then swing together or apart, depending on whether the tube currents are in the same or opposite directions.

Force On A Conductor Balance
To demonstrate that when a current is passed through a conductor in a magnetic field, it is subjected to attraction or repulsion depending upon the direction of current in it. The apparatus consists of a plastic base 160 x 140 mm on which two contact pillars are mounted. Each pillar is provided with an external circuit. A balanced beam is supported by the pillars on two bearings which form the fulcrum. Two screwed masses are provided in the beam system, one moving vertically for the adjustment of sensitivity and the other moving horizontally for the adjustment of the equilibrium position, when no current is flowing. Scale marked 0 to 75 x 1 mm, rider of 1 gm. weight, with instruction manual.

Helmholtz Coil
Helmholtz Coils are a special arrangement of coils that are placed in such a way as to generate a very uniform magnetic field between them when a current is applied. The strength of the magnetic field is proportional to the number of turns in the coils and the current applied to them. The Supertek Helmholtz Coils setup consists of two field coils mounted on a track to provide a uniform magnetic field between the coils. The proper separation for Helmholtz coils is marked on the track. A pair of precision coils and 400 turns of wire are wound on heat resistant former of about 150 mm diameter.

Newton’s / Coulomb’s Law Demonstration
Study the concepts of Newton?s and Coulomb?s laws with this apparatus. This apparatus can be used to demonstrate repulsion, attraction of charged bodies and provides the ability to measure the angle between the 2 strings and thus the force between the two charged spheres. The charge can be provided by a Wimshurst machine or a Van de Graff generator or by simply rubbing a plastic rule with on a duster. Includes manual.
