Hey guys, Most physics or introductory electronics books that I have read begin the topic of electricity by introducing static electricity. The books introduce static electricity by either talking about the amber and the wool experiment or the glass rod and the silk cloth. My question is, what in fact is going on when the glass rod and the silk cloth are rubbed together and then later, attract? One of the materials involved in the electron transfer must have a net charge correct? What is the difference between electrostatic induction and the triboelectric effect?
