Since this is taught over the highly accelerated summer session, ancillary topics covered will vary according to the student’s interests and majors. The instructor’s primary objective is to make the course as understandable and painless as possible and ensure every student passes the course. The instructor will be available for tutoring during scheduled office hours (to be announced) and by appointment. Textbook: Physics for Scientists and Engineers, by Wolfson & Pasachoff, Addison Wesley. Volume II, Custom Edition for University of California, San Diego Please note that this custom edition of the textbook includes only the chapters required for this course, namely, only the section on Electricity and Magnetism. Anyone having carried around a standard Physics, Chemistry, Biology or Calculus textbook covering an entire year worth of material will appreciate the relief experienced by the lower back. Lectures and Homework: Since this is an accelerated course, new material will be presented at lecture on Monday, Tuesday and Wednesday of each week. Homework will be assigned but not collected. It is highly recommended that you keep abreast of the assignments as physics is not a “spectator sport”. In addition to the lectures, problem solving sessions will be conducted weekly by the TA in order to facilitate your complete mastery of the assigned homework. You should attend these sessions, especially if you did not master a calculus-based Physics E&M course at the high school level. Thursdays will be devoted to review in preparation for the unit exam each Friday except for Unit 5 which will be given on Thursday. A Practice Exam will be handed out at the end of Wednesday lecture and should be at least attempted if not completed by the student for the review session. STUDY NOTES: you will get the most out of this course by reading the assigned material in the textbook prior to the lecture. There are two advantages to this approach: 1) you will have seen the material once and can ask considered and meaningful questions during the lecture to clarify your understanding and 2) you won’t have to divert your attention from the lecture content to take notes. 2 Exams and Grading: Unit Exams will be multiple choice and the problems have been designed to probe a range of skills as partial credit cannot be assigned. You must bring your own Scantron Form which may be purchased at the bookstore for a modest price. Exams must be taken at the time scheduled. Those missed for a legitimate reason can only be made up by special arrangement with the instructor and must be made up within the shortest reasonable time. For each Unit Exam you are allowed to bring one 8 ½ by 11 sheet of notes which you may prepare on both sides. A formula sheet will be handed out at the beginning of each week as a sample which you may use as-is or copy to your own sheet as you prefer. You should remember that the course is cumulative, that is, some formulas from previous units will be needed as we progress, so you will want to extend the prompt materials in the handout as necessary. I will announce in advance what support materials you may bring to the Final Exam. Friday of the last week will be devoted to a review in preparation for the Final Exam the following day. The Final Exam will consist of three components; a multiple-choice section to probe basic understanding of fundamental concepts, a comprehensive intermediate section (not multiple-guess) and a very challenging third section designed to identify the shining stars of the class. Be prepared to be puzzled by the last section which no one has ever completed even though typically half the class receives a grade of “A”. You will NOT need a Scantron Form for the Final Exam as all sections of it will be hand graded and partial credit will be assigned on all problems. Please note that working the homework problems will prepare you for the Final Exam. Unit Exams will count 60% towards the final grade. The Final Exam on Saturday, September 8 will be cumulative and will count 40%. Final course grades will be curved. Please note that, according to UCSD policy, you must bring your picture ID to the Final Exam. Academic Honesty: The UCSD and Physics Department academic honesty policies and procedures, as outlined in the catalog are applicable to all aspects of this course. End of Course: A grade of I (Incomplete) will be given only in circumstances of unusual need, when it is not reasonably possible for the student to complete all course requirements by the last day of class. Any student seeking a grade of Incomplete must sign an agreement with the instructor specifying the task(s) to be completed and the date by which the work is to be completed. If the tasks are not completed, the grade of Incomplete will be automatically changed to the student’s default value. 3 PHYSICS 2B – Electricity & Magnetism Course Outline 2009 – Summer Session II Week Dates Topics 1 August 3 – August 7 2 August 10 – August 14 3 August 17 – August 21 4 August 24 – August 28 5 August 21 – September 4 September 5 Chapters Electric Charges Coulomb Force Law Electric Fields Gauss’ Law Electric Potential Work & Energy Capacitors Current, Resistance Ohm’s Law Electric Power Circuits Magnetic Field Ampere’s Law Law of Biot & Savart Electromagnetic Induction Inductors Alternating Current AC Circuits Electromagnetic Waves Maxwell’s Equations FINAL EXAM 23 - 24 25 – 26 27 – 28 29 - 32 33 - 34 4 Physics 2B Homework Assignments Unit 1 2 3 4 5 Chapter 23 - 2 23 – 3 23 – 4 23 – 5 23 – 6 24 – 1 24 – 2 24 - 3 24 - 4 24 - 5 24 - 6 25 - 2 25 - 3 25 - 4 25 - 5 26 - 1 26 - 2 26 - 3 26 - 4 26 - 5 26 – 6 26 – 7 27 - 1 27 – 2 27 - 3 27 - 4 28 - 1 28 - 2 28 - 3 28 - 4 28 - 5 28 - 6 29 - 2 29 - 3 29 - 4 29 - 5 30 - 1 30 – 2 30 - 3 30 - 4 30 - 5 31 – 2, 3 31 – 4 32 – 1, 2 32 - 3 32 - 4 33 - 1 33 - 2 33 – 3,4,5 33 - 6 34 - 4 34 - 5 34 – 8 34 – 10 34 – 11 Page 594 595 595 596 597 624 624 625 625 627 627 653 654 655 656 679 679 679 680 680 681 682 704 705 705 706 736 737 737 738 739 739 764 765 766 767 796 798 798 799 800 827 830 848 849 850 877 877 878 879 910 911 911 911 912 Sample Problems 2 7, 11, 16, 17, 21 25, 27 33, 37, 45, 47, 49 57, 65 1, 3 5, 7 11, 13 17, 25, 26, 31, 35 39 Hint: near vs. far field 45, 47, 57 1, 12, 13, 17 18, 30, 35, 37 47, 51 53, 58 1, 5 9, 12 17 33, 35 46 51, 53, 57 65, 68 1, 7 27, 30 45, 53 3 5, 7 22, 26 29 43, 55 55 1, 3 15, 23, 27, 30 33, 35, 40* 46, 47, 53 1, 7, 10 18, 20, 24 27, 33, 35 39, 40, 41 43, 47 2, 3, 7, 9, 17, 25, 27, 29* 39*, 40*, 41* 1, 3, 4, 9, 11, 13, 22* 25, 27 39, 49 1, 3, 5 13, 17, 19 27, 29, 39* 58, 59 7, 8 21 31 39 55 Topics Electric Charges Coulomb’s Law The Electric Field Charge Distributions Matter in Electric Fields Electric Field Lines Electric Flux Gauss’s Law Applications of Gauss Arbitrary Charge Distributions Conductors Potential Difference Calculating The Potential Potential vs. Field Charged Conductors Energy of Charge Distributions Isolated Conductors Electric Field Energy Capacitors Capacitor Energy Storage Capacitor Networks Dielectrics Electric Current Conduction Mechanisms Resistance and Ohm’s Law Electric Power Electric Circuits and Symbols Electromotive Force Resistor Networks Kirchhoff’s Laws Measuring Instruments Circuits with Capacitors Force on a Moving Charge Free Charge Motion in a Field Force on an Electric Current The Current Loop The Biot-Savart Law Force Between Two Conductors Ampere’s Law Applications Solenoids & Toroids Faraday’s Law & Induction Induced Electric Fields Inductance Inductors in Circuits Magnetic Energy Alternating Current Circuit Elements LC, RLC Circuits and Power Transformers & Power Supplies Electromagnetic Waves Speed of EM Waves Polarization Energy in EM Waves Radiation Pressure
