Plasma sphere OPTIKA SCIENCE. By bringing a finger close to the surface, due to the conductivity of the human body, the discharges are concentrated in the vicinity of the finger. Therefore the sphere can be used to distinguish conductive objects from insulating ones. It can also be used to demonstrate the existence and nature of electromagnetic waves
Plasma sphere OPTIKA SCIENCE.
Glass sphere with a diameter of 20 cm, containing a mixture of rarefied gases.
The central electrode has an alternating voltage of 10,000 volts, thus generating discharges that propagate outwards.
By bringing a finger close to the surface, due to the conductivity of the human body, the discharges are concentrated in the vicinity of the finger. The sphere can therefore be used to distinguish conductive objects from insulating ones. It can also be used to demonstrate the existence and nature of electromagnetic waves.
In fact, by bringing a neon tube close to it, it lights up thanks to the energy carried by the electromagnetic waves. Interposing a sheet of paper, the phenomenon is maintained, because the waves can pass through it. However, with a foil of conductive material such as aluminum, the waves cease due to the shielding effect.
