Charging by induction. 1) Charged rod brought close to isolated conductor. 2) Charge separation. 3) Earth conductor. 4) Remove charged rod. A charged polythene rod can be used to transfer charge onto an insulated conductor without the two object coming into contact. The negatively charged polythene rod is brought close to the conductor.

What causes static electricity Edinformatics
The triboelectric effect is a type of contact electrification in which certain materials become electrically charged after coming into contact with another different material and are then separated. Most everyday static electricity is triboelectric.

ElectrostaticsWikipedia
Electrostatics is a branch of physics that studies electric charges at rest.. Since classical physics it has been known that some materials such as amber attract lightweight particles after rubbing.The Greek word for amber ήλεκτρον or electron was thus the source of the word electricity . Electrostatic phenomena arise from the forces that electric charges exert on each other.

Electrostatic inductionWikipedia
Electrostatic induction also known as "electrostatic influence" or simply "influence" in Europe and Latin America is a redistribution of electric 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.
