An air ioniser (or negative ion generator or Chizhevsky's chandelier) is a device that uses high voltage to ionise (electrically charge) air molecules.Negative ions, or anions, are particles with one or more extra electrons, conferring a net negative charge to the particle.ost commercial air purifiers are designed to generate negative ions. Another type of air ioniser is the ESD ioniser (balanced ion generator) used to neutralise static charge. In 2002, Cecil Alfred 'Coppy' Laws was credited with being the inventor of the domestic air ioniser in an obituary in The Independent newspaper.
Source: NASA. The ionosphere is defined as the layer of the Earth's atmosphere that is ionized by solar and cosmic radiation. Short wave radiation that penetrates the Earth's atmosphere does not reach the surface. A few examples of short wave radiation are x-rays, ultraviolet and gamma rays.When these waves pass through the atmosphere, they ionize molecules of oxygen and nitrogen and create a thin ionized region known as the ionosphere.he ionosphere is very important because it can be used to help transmit radio waves across the globe. The radio waves are able to bounce off the ionosphere for communication purposes.
