Friction Electrification
★Exhibit Content: Static electricity phenomenon, triboelectric effect ★Interaction: Mechanical interaction ★Operation: 1. Repeatedly rub the glass surface with a silk handkerchief; 2. Bring the glass rod close to the paper scraps and observe the phenomenon of the paper scraps below being attracted by static electricity. ★Exhibit Description: The triboelectric effect exhibit consists of a silk handkerchief, a glass rod, paper scraps, a display stand, etc., demonstrating the scientific principle of triboelectric charging. Visitors can use the glass rod repeatedly rubbed with the silk handkerchief to attract paper scraps, thereby understanding that charged objects can attract small light objects and learning about triboelectric charging. ★Scientific Principle: The phenomenon in which two different objects rub against each other, causing one object to become positively charged and the other negatively charged, is called triboelectric charging. A rubbed object has the property of attracting small light objects. When two objects rub against each other, one object loses some electrons, and the other gains these electrons, causing them to become positively and negatively charged, respectively. A charged object generates an electric field around it, which exerts an attractive force on nearby small light objects, causing them to be attracted to the charged object. Therefore, a rubbed object, being charged, has the property of attracting small light objects.
