Introductory Physics II Electricity, Magnetism and Optics by Robert G. Brown Duke University Physics Department Durham, NC 27708-0305 [email protected] Copyright Notice Copyright Robert G. Brown 1993, 2007, 2013 Notice Thisphysicstextbook isdesignedto supportmy personalteachingactivities atDuke University, in particular teaching its Physics 141/142,151/152,or 161/162series (Introductory Physics for life science majors, engineers, or potential physics majors, respectively). It is freely available in its entirety in a downloadable PDF form or to be read online at: http://www.phy.duke.edu/ rgb/Class/introphysics 2.php ∼ It is also available in an inexpensive (really!) print version via Lulu press here: http://www.lulu.com/shop/product-21025164.html where readers/users can voluntarily help support or reward the author by purchasing either this paper copy or one of the even more inexpensive electronic copies. By making the book available in these various media at a cost ranging from free to cheap, I enable the text can be used by students all over the world where each student can pay (or not) according to their means. Nevertheless, I am hoping that students who truly find this work useful will purchase a copy through Lulu or a bookseller (whenthelatteroptionbecomesavailable),ifonlytohelpsubsidize me while I continue to write inexpensive textbooks in physics or other subjects. This textbook is organized for ease of presentation and ease of learning. In particular, they are hierarchicallyorganizedin a waythat directly supports efficientlearning. They arealso remarkably complete intheirpresentationandcontainmoderatelydetailedderivationsofmanyoftheimportant equations and relations from first principles while not skimping on simpler heuristic or conceptual explanations as well. As a “live” document (one I actively use and frequently change, adding or deleting material or altering the presentation in some way), this textbook may have errors great and small, “stub” sectionswhere I intend to addcontentatsome latertime but haven’tyetfinished it, andthey cover and omit topics according to my own view of what is or isn’t important to cover in a one-semester course. Expect them to change with little warning or announcement as I add content or correct errors. Purchasersofthe paper versionshouldbe awareofits probableimperfectionand be preparedto either live with it or mark up their copy with corrections or additions as need be. The latest (and hopefully most complete and correct) version is always available for free online anyway, and people who have paid for a paper copy are especially welcome to access and retrieve it. I cherish good-hearted communication from students or other instructors pointing out errors or suggesting new content (and have in the past done my best to implement many such corrections or suggestions).
