Wimshurst Machine, Superior
This traditional electrostatic charge generator consists of two parallel transparent discs supported on rigid uprights. Each disc has a number of radial aluminium segments and are driven in opposite directions by hand wheel and belt. The electrostatic charge on aluminium segments is collected by combs mounted on either end of the discs and stored in the two leyden jars. When the potential difference between the jars is sufficiently high. A spark will flow between the adjustable discharging spheres.

Electromagnetic Induction Demonstrator
Lab EquipmentsElectromagnetic Induction Demonstrator kit is used for demonstrating the important experiments performed by Faraday and how they lead to some of the significant conclusions in electromagnetism. It is designed to perform studies even beyond the basic experiments. It comprises of three solenoids of 20, 40 and 80 turns, each of identical cross section, mounted on a transparent base along with a milliammeter. These three coils of different lengths are provided to understand the effect of length of coil on induced current. Repeatedly inserting a magnet into the coil and removing it causes electric current to flow
through the coil, which can be read directly from the milliammeter. Also notice that the milliammeter shows zero current when the magnet is not moving. Using this apparatus,
students can study correlations between induced current to that of magnetic field strength, number of turns of coil, magnetic field polarity and speed. Requires 1.5V dry cell battery (not included) -
Conductivity Meter
Lab EquipmentsA simple apparatus for testing the electrical conductivity of liquids. Connect the apparatus to the main supply and place the electrodes in the liquid used for testing. A strong conductor is a material that will let electric charges to flow through it very easy
and therefore the bulb of conductivity meter glows brightly. The weak conductors allow electric charges to flow through it slowly and therefore the bulb of conductivity meter glows dimly. The bad conductors do not allow electric charges to flow through it
and therefore the bulb of conductivity meter does not glow at all. Bulb provided is large and bright enough to be seen by the entire class. The conductivity meter includes a clamp on the back for attaching to a support stand. Instructions and appliance bulb are also included. -
