Product Details:

The small Tesla Coil produces an alternating high voltage potential which attracts or repels free electrons. When the electrons collide with the gaseous atoms and molecules inside the globe, the gas particles are ionized creating even more electrons, as well as, positive ions. A plasma is formed. When electrons return to the ionized gas, light is produced. Touching the globe with your finger provides a ground, an addition source or sink of electrons. You can also observe super, neat, wow effects by moving a fluorescent tube or neon light near the plasma globe. They will light up in your hands.

Product Details:

By means of null method this balance measures tiny forces, it possess adjustable counterweight and an optical lever. To measure the repulsive force between parallel current-carrying conductors a pair of straight aluminium rods are given. Attractive force between charged capacitor plates ,a pair of plates are also included. In the electromagnetic experiment sufficient deflection may be caused by means of a current of 10-20A. For returning the balance to its original position, fractional weights are added to a small pan which is attached to the upper conductor rod, thus force between the conductors are measured. The dynamic definition of the Ampere or to determine the permeability of Air may be confirmed by interpretation of the result. Permittivity of the air may be observed by the analogous electrostatic experiment. An indirect estimate of the speed of light may be made from these two values. The whole experiment requires a diode laser & scale for the optical lever, fractional weight set for the current experiment, multimetyer for volts and amps, a 300V variable high voltage source and an AC or Dc current source for 10-20A. A detailed manual is included.
