Electric wind is an electrostatic phenomenon that is produced in the presence of electric charge points due to the movement of the ions caused by the presence of the charge on the tip itself.
Assuming, for example, that the tip is charged negatively, it will attract the positive ions present in the air and reject negative ions. The latter, moving away from the tip quickly, generate a perceptible movement of motion as an air movement (such as a slight wind). On the tip, for the third principle of dynamics, there is a direct force in the direction opposite to the wind that it generates.
The phenomenon occurs in the presence of punches or conductors with small bend radius. In these areas, the surface charge density is higher than in areas with a large radius of curvature: consequently the electric field on the first is greater.
The electric wind can be observed, for example, by bringing near the tip of an electric conductor loaded with the flame of a candle: the latter bends under the action of the "electron wind", that is, the air movement due to ions, partially present in the atmosphere, in part formatted near the tip.
Another example may be the electric hammock (a conductor provided with a series of metal rays folded in the same direction and ending with a tip) where the ions attracted by the bits yield their amount of motion to them by generating a rotating motion opposite the direction in which the tips are oriented.
