Static electricity induction charging

Electrostatic induction The process of inducing static electric charges on a body by bringing it near other bodies that carry high electrostatic charges. 

Static electricity is produced by the build-up of electrons on weak electrical conductors or insulating materials. These materials may be gaseous, liquid or solid and may include flammable liquids, powders, plastic films and granules. The generation of static may be caused by the rapid separation of highly insulated materials by friction or by transfer from one highly charged material to another in an electric field by induction. 

The permanent polarization of single bonds, or induction-static (/ ), as it is often called, originates whenever there is a covalent bondTBetween atoms which are electrically dissimilar. In a covalent bond between two like atoms the shared electron pair is midway between the two nuclei, and the valence electrons of each atom completely neutralize the positive charge of each atomic kernel (Fig. 1). In a covalent bond between two atoms such as carbon and chlorine, however, chlorine has a greater affinity for electrons than carbon.
