1 SYLLABUS Lecture: MWF 1 2:05 PM, Building 8 Room 241 Instructor: Dr. Matthew S. Povich Building 8, Room 216; (909) ; mspovich@cpp.edu Office hours: M 2:15-4 PM in room , F 11 AM-noon, and by appointment Learning Assistant: Ian Marsh; immarsh@cpp.edu; Office hour T 4-5 PM in Course Website on Blackboard: Log in with your Cal Poly Pomona Bronconame and password. This is your one-stop shop for all course materials, including this syllabus! I will rely on to communicate with you, so please check your cpp.edu address at least once per week. Required Textbook: Introduction to Electrodynamics, Fourth Edition by David J. Griffiths. This is the most popular advanced undergraduate textbook on electricity and magnetism (it s basically the Bible for electricity and magnetism at the undergraduate level) and it is well worth purchasing your own copy, to keep for your reference in the future (we used the same book in PHY 314). Recommended Background Text: Fundamentals of Physics, 9th ed. by Halliday, Resnick, and Walker (PHY 133 textbook, if you need some refreshing on the basics) Pre-requisites: PHY 308, 309, 314, MAT 215, 216 or equivalent Course Description The experimental investigation by which Ampere established the law of the mechanical action between electric currents is one of the most brilliant achievements in science It is perfect in form, and unassailable in accuracy, and it is summed up in a formula from which all the phenomena may be deduced, and which must always remain the cardinal formula of electro-dynamics. James Clerk Maxwell, A Treatise on Electricity and Magnetism (1873), Vol. 2, 162. Physics 315 is the second in a two-quarter, upper-division course sequence on classical electricity and magnetism. This course is required for all Physics majors at Cal Poly Pomona (and most other universities). We will apply mathematical tools, with a heavy emphasis on vector calculus, to develop a theoretical foundation for understanding electric and magnetic phenomena. Learning Goals 1. Students should be able to translate a physical description of a junior-level electromagnetism problem to a mathematical equation necessary to solve it. 2. Students will see the various laws presented in the course as part of the coherent field theory of electromagnetism (Maxwell s equations). 3. Students accept responsibility for their own learning. They will be aware of what they do and do not understand about physical phenomena and classes of problem. Cal Poly Pomona PHY 315 Syllabus Dr. Povich 1

2 Course Structure and Requirements Physics 315 covers very abstract concepts with considerable mathematical rigor. Many students find electricity and magnetism to be among the most challenging physics topics, so you should expect to expend considerable time and effort to master the material. In addition to attending Lectures, you should plan to spend at least 9-12 hours per week outside of class on assigned readings, homework, and studying. If you find yourself struggling or falling behind, please do not hesitate to contact me. Please take advantage of office hours, and make an appointment if you can t make it to my regular office hours! Lecture and Discussion The three 65-minute class meetings per week will include lecture, demos, discussion (involving the whole class or in small groups), and group tutorial activities. I will not take attendance every day, but I will learn your name and may occasionally call on you to contribute to in-class discussions. Class participation counts as part of your overall grade. I will provide you with a multicolored answer card that you will use every class to answer inclass, multiple-choice questions that motivate discussion of key concepts with your classmates. Please have your answer card ready on your desk at the beginning of each class. If you lose your card, you can download and print (in color, please) a replacement from Blackboard. Reading Assignments Reading assignments from Griffiths are listed below in the Schedule. The reading is required and very important. While the reading assignments are not lengthy, the text is conceptually and mathematically dense, so you can expect to re-read many sections of the book multiple times. To make sure you are keeping up, you can expect occasional, brief reading pop-quizzes (two or three questions) at the beginning of class! I will drop the two lowest reading quizzes from your final grade. Guidelines: Reading quizzes are closed-book but open-notes, so you ll want to do the readings and take notes from your reading in advance. Homework An important part of this course will be weekly homework (HW) sets, posted on Blackboard. HW assignments will be due at the beginning of class on the days specified in the Schedule (usually Friday). I will drop the lowest HW score from your final grade. Guidelines: I will be happy to offer HW assistance in office hours, provided that you show evidence that you have already put substantial thought into the problems. I welcome and encourage students to discuss the HW problems in study groups, however you must write out your final solutions by yourself and in your own words. Exams Like the rest of the course, exams will be designed primarily to test your mastery of concepts and application of physical laws, not just your ability to memorize facts and equations. There will be one Midterm and one (cumulative) Final Exam, administered in the same room where we have lecture. There will be no make-up exams! Guidelines: You may bring a calculator and pencil/eraser to the exams. Notes, computers, ipods/ipads, smartphones and all other outside aids/devices will not be allowed. Obviously, copying other students exams is forbidden! Cal Poly Pomona PHY 315 Syllabus Dr. Povich 2

3 Collaborative Learning Environment We all want our classroom to be a safe and diversity-sensitive learning environment that respects the rights, dignity, and welfare of all students and instructors. When we employ group discussion in our class that may invite conflict as you try to convince your peers of a correct answer, please be especially aware of your debate tactics. Please feel free to contact me at any time regarding your individual circumstances and needs, especially if you have concerns or disabilities that might affect you in this course. I promise to make every reasonable effort to accommodate your situation. Students with documented learning disabilities requiring special accommodations should notify the Disability Resource Center ( , Room 9-103). Following this principle of respect for others, the following behaviors are not permitted in our classroom: use of laptops and cell phones, eating, distracting conversations with neighbors, and similar disruptive behavior. Students caught engaging in these activities will be asked to leave the classroom immediately and be marked absent (yes, seriously!). Academic Honesty Please make sure that you have read and fully understood all the guidelines governing assignments and exams for this course (above) and the statement on academic integrity that appears in the University catalog. I work on the assumption that all of our interactions are based on openness, honesty, and good faith, but I will take serious action if this trust is violated. Grading Grades are meant to reflect your understanding and effort. Your final grade will be calculated using the following weighting: Number % Reading Quizzes TBD* 10 Participation 5 Homework Assignments 7* 20 Midterm Exams 2 30 Final Exam (cumulative) 1 35 TOTAL 100 *Your lowest HW and two lowest Reading Quiz scores will be dropped from your average.

4 Schedule We will try to keep to this schedule, but in the (likely) event that later on we find that modifications are required I will produce an updated version. Unless otherwise noted, all reading assignments are from the Griffiths textbook.

If the strike takes place, class will not meet on those days (if the strike ends early, we will of course immediately return to our regularly scheduled class meetings for the rest of the quarter). I will keep you updated via and advise you of alternative activities to do instead of coming to class on those days. Cal Poly Pomona PHY 315 Syllabus Dr. Povich 5
