Electrostatic induction also known as "Electrostatic Influence" or simply "Influence" in Europe and Latin America (see for instance Wilhelm Holtz influence machine), is a redistribution of electrical charge in an object, caused by the influence of nearby charges. In the presence of a charged body, an insulated conductor develops a positive charge on one end and a negative charge on the other end. Induction was discovered by British scientist John Canton in 1753 and Swedish professor Johan Carl Wilcke in 1762. Electrostatic generators, such as the Wimshurst machine, the Van de Graaff generator and the electrophorus, use this principle. Due to induction, the electrostatic potential (voltage) is constant at any point throughout a conductor. Electrostatic Induction is also responsible for the attraction of light nonconductive objects, such as balloons, paper or styrofoam scraps, to static electric charges. Electrostatic induction laws apply in dynamic situations as far as the Quasistatic approximation is valid. This is for instance the case for the capacitor in the Electrical network frame. Electrostatic induction should not be confused with Electromagnetic induction.
