Shocked by static? Mixed up about magnets? Curious about currents? This book will help you get beyond memorizing electricity-related formulas, rules, and procedures so you can understand the topic at a deep level deep enough to teach it with confidence and comfort. By covering the basics of static electricity, current electricity, and magnetism, the book develops a scientific model showing that electricity and magnetism are really the same phenomenon in different forms. A bonus access to interactive software that you can download from the NSTA Web site. The software will help you investigate electrical circuits from simple to complex without having to buy a lot of expensive materials (or risking electrocution!). Electricity and Magnetism is the fifth title in the award-winning NSTA Press Stop Faking It! Series. As author Bill Robertson writes, The book you have in your hands is not a textbook. It is, however, designed to help you get science at a level you never thought possible, and also to bring you to the point where tackling more traditional science resources won t be a terrifying, lump-in-your-throat, I-don t-think-I ll-survive experience. Robertson serves as your friendly guide, one with a comforting knack for anticipating fears, meeting information needs, and entertaining as he edifies.
Come on. Do some research before publishing a book. If the currents in both wires flow in the same direction, the forces acting on the two wires are attractive and they will move towards each other. Conversely, if the currents flow in the opposite directions, the forces will be repulsive and the wires will pull away.
