An electrostatic pinwheel, or corona spinner, attached to a small Wimshurst machine (electrostatic generator) is shown stationary and rotating. Ion wind, ionic wind, corona wind or electric wind is the airflow of charged particles induced by electrostatic forces linked to corona discharge arising at the tips of some sharp conductors (such as points or blades) subjected to high voltage relative ...
In 1941 Van Arkel recognised three extreme materials and associated bonding types. Using 36 main group elements, such as metals, metalloids and non-metals, he placed ionic, metallic and covalent bonds on the corners of an equilateral triangle, as well as suggested intermediate species.
Air ioniser and purifier with its dust collection plates removed. Air ionisers are used in air purifiers to remove particles from air. [3] Airborne particles become charged as they attract charged ions from the ioniser by electrostatic attraction.
The density of air or atmospheric density, denoted ρ, [1] is the mass per unit volume of Earth's atmosphere.Air density, like air pressure, decreases with increasing altitude.
Electron transfer between lithium (Li) and fluorine (F). Forming an ionic bond, Li and F become Li + and F − ions.. An ion (/ ˈ aɪ. ɒ n,-ən /) [1] is an atom or molecule with a net electrical charge.
Ion-exchange resin beads. An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange, that is also known as an ionex. [1] It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.
In electromagnetism, an eddy current (also called Foucault's current) is a loop of electric current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction or by the relative motion of a conductor in a magnetic field.
