Electricity and Magnetism Electrostatics: LAWS: Like charges repel Unlike charges attract Neutral objects attract charged objects (temporary induced dipoles (London dispersion forces) that cause separation of charge. Fattraction > Frepulsion Electric charge is always conserved Charging by induction: Charging: neutral to start By Grounding: a neutral object that can receive or supply large numbers of electron without significantly altering its own charge (earth and people) Come away with opposite charge Charging by Conduction: through contact and electrons are equally transferred and equally shared, kiss up and repel, and both have the same charge (electroscopes) same charge
