Principle of electrostatic adsorption

When an object with static electricity is close to another object with no static electricity, due to electrostatic induction, the side of the non-static object close to the electrostatic object will generate a charge with the opposite polarity to the charge carried by the charged object, and the other side will generate the same charge. A large number of charges of the same polarity will exhibit electrostatic attraction due to the attraction of opposite charges. This is the principle of electrostatic adsorption.
