Course information Course Code: 203-NYB-05 Course Title: Electricity & Magnetism Weighting: 3-2-3 Course Credits: 2.66 Total Course Hours: 75 Pre-requisites: Mechanics (203-NYA-05), Waves and Modern Physics (203-NYC-05), Calculus I (201-NYA-05), and Calculus II (201-NYB-05.) 2. Place in the program Physics NYB is the last of three obligatory Ministerial Physics courses that have to be taken by all students in a Science Program. Students usually take this course during their third semester and after, or at least concurrently with, Mathematics 201-NYB (Calculus II integrals). Following a trend established in Physics NYC, students are obliged to combine many of the concepts and techniques they have learned (principally in Physics, Chemistry, and Mathematics) so as to tackle new kinds of problems and applications that require a more comprehensive knowledge and set of abilities than previous courses. Physics NYB deals with subject matter whose principles and applications form the basis of our understanding of an enormous number of fundamental phenomena, practical devices, and widely-used processes that pervade our technological society (see end of this course outline). Since
Electricity and Magnetism 2/5 all science students can be expected to spend most of their professional lives in environments where such phenomena, devices, and processes are an integral part of normal operations, it is essential that they acquire a thorough understanding of these things and that they be able to apply them to concrete situations. 3. Contribution to exit profile As described in the Science Program (200.B0), students must possess certain attributes upon graduation. To varying degrees in this course, students will learn to: Apply the experimental method Take a systematic approach to problem solving Use the appropriate data-processing technologies Reason logically Communicate effectively Learn autonomously Work as members of a team Make connections between science, technology and social progress Become familiar with the context in which scientific concepts are discovered and developed Adopt attitudes that are useful for scientific work Apply what they have learned to new situations 4. Specific Course Objectives The course 203-NYB-05 is designed to fulfill the 00US objectives: Analyze various situations and phenomena in physics using the basic laws of electricity and magnetism, for which the performance criteria are: Proper use of concepts, principles and laws Adequate representation of situations in physics Graphic and mathematical representations adapted to the nature of the problem Justification of steps in the analysis of situations Rigorous application of the laws of electricity and magnetism Critical evaluation of results Interpretation of the limits of the models Meticulous experimentation Appropriate use of measuring instruments Laboratory report in line with established standards The experimental component of the 203-NYB-05 course will also aim to fulfill the optional 00UV objectives: Apply the experimental method in a scientific field, for which performance criteria are: Proper use of concepts, laws and principles Rigorous application of concepts, laws and principles Appropriate use of terminology Correct representation in a drawing or graph or in mathematical form Consistency and rigour in problem solving, and justification of the approach used Observance of the experimental method and, where applicable, the experimental procedure Justification of the approach used Assessment of the plausibility of the results In addition, completion of this course is necessary to complete the Comprehensive Assessment (CA) of the Science Program, which aims to fulfill the 00UU objectives: Apply acquired knowledge to one or more subjects in the sciences, for which the performance criteria are: Use of an interdisciplinary approach Consistency and rigour in problem-solving, and justification of the approach used Observance of the experimental method and, where applicable, the experimental procedure Clarity and precision in oral and written communication Correct use of the appropriate data-processing technology Appropriate choice of documents or laboratory instruments Significant contribution to the team Appropriate connections between science, technology and social progress. 5. Course Content 5.1 Teaching Schedule We meet five hours a week. These are divided into three hours of theory and two hours of lab work or problem solving. Problem sessions are organized to develop problem solving skills and to promote team work. Students are expected to be in class on time, and to behave themselves in a dignified manner. Attendance is necessary but not sufficient to ensure success. While it is suggested that students spend at least three hours every week to complete the requirements of the course, most students will require close to five hours. It is absolutely essential that students arrange their schedule to include this period of preparation. 5.2 Teaching Method The course will be presented using a mix of active learning activities, lectures, in-class problem solving, laboratory experiments and demonstrations. Laboratory periods will be used for experiments as well as class tests and lectures. 5.3 Textbook The textbook used in this course, is free open source text from OpenStax called University Physics developped by Rice University. (https://openstax.org) This three volume textbook will be used this semester as a primary reference. Sections will be assigned for reading before a topic is discussed in class, and problems will be assigned from this textbook. You are expected to come to class prepared, having
Electricity and Magnetism 3/5 read the assigned sections, and to solve all assigned problems before the quizzes and tests. All lab experiments, problem sessions, and other relevant documents and information, are available on your class website (www.remipoirier.com). It is your responsibility to download and print the documents BEFORE class. 5.4 Problem Solving This should become your mantra; solve problems... solve problems... This class is problem-solving oriented. I wish to see if you are able to translate a written problem into mathematical notation, and solve it using the techniques learned in class. A list of suggested problems from the end of chapter problems in the textbook, will be made available through the class website. It is the student responsibility to practice all suggested problems before the test. 5.5 Experiments Physics is an experimental science, and as such, experiments are of paramount importance to this class. The lab component of the course is divided into two sections: Lab Reports and Experiment Logs. 5.5.1 Lab Reports There will be three (3) evaluated lab reports during the semester, they must be typed using a software such as, LibreOffice Writer or Microsoft Word. Graphs must be computer generated, using Libre Office Calc, or Microsoft Excel. Equations must be typeset in the text with an equation editor. Further details regarding the format and content of lab reports will be given during the first lab session and are provided in your website (www.remipoirier.com). Formal lab reports must be submitted within two weeks using the Omnivox system. Late lab reports will be accepted with a penalty of -10% for the next day, and -25% Deadlines for the day after the next. Lab reports submitted later than two days after the deadline receive a grade of zero for all the students of the group, even if they have attended and participated in the lab. The same penalty schedule will be applied to any homework that needs to be submitted for evaluation. The lab reports will be submitted electronically in PDF, ODT (libreoffice), or DOCX (MicrosoftWord) format. Apple Pages documents are not accepted as they are not compatible with the evaluation software used; install and use LibreOffice instead. It will be your responsibility to make sure the documents are complete, and that all parts, including equations and graphs, display correctly before you send it for evaluation. Reports submitted in the wrong format will not be accepted. It is imperative that you write lab reports in proper English. Poor English leads to a lack of clarity that negatively affects your grade. Electronic Format 5.5.2 Experiment Logs During experiments for which no lab reports are necessary, you will nevertheless have to submit a log of your activities, measurements, and calculations. These logs will take different formats and are submitted either immediately at the end of the lab period, or after a few days following the lab. Further details regarding the format and content of the experiment logs will be given during the lab session and are provided in your website. 5.6 Quizzes Quizzes will be scheduled at roughly weekly intervals, throughout the semester, except when a test is scheduled. At the end, the two (2) worst quizzes will be discarded. 5.7 Tests These are 100-minutes tests, held during a lab period, requiring the solution of harder problems. There will be two tests during the semester: the first one held on February 26, the
Electricity and Magnetism 4/5 second one on April 23. These dates are subject to change; any change will be posted on the class website. 5.8 Integrative Activity As required by the Science Program, an integrative activity (IA) in which you must integrate the physics concepts discussed in this class with concepts related to other sciences will be held at the end of the semester. This IA, will be an essay on a science topic. More information will be provided in class regarding this topic. If you have previously done an integrative activity in physics, you must do another one on a different topic for this class. 5.9 Final Exam A three-hour final exam will be held during the official final exam period. The final exam will consist of two sections covering all the material presented in the course, including labs; one section will consist of several multiple choice questions, the other of four to six long problems. The purpose of the final exam is to evaluate your overall understanding of the concepts presented in the course. 5.10 List of Equations For the Tests and Final Exam, a list of equations will not be provided by the teacher. On the other hand, you will be allowed to bring one sheet of handwritten equations. This list must be letter sized (8.5 x 11 inches squared) only contain mathematical equations, physical constants, and physics equations relevant for the topics under evaluation. The teacher will not provide additional information to you if you have not made a complete list of equations. Full solutions of problems, derivations of equations or diagrams are not welcome on the equation sheet, and the teacher may remove the list if you included any of those on the sheet. The equation sheet will be picked up with the test and will not be given back to you; you will therefore have to make three lists of equations during the semester: one for each of the tests and one for the final exam. During quizzes in class, the relevant equations and physical constants will be provided for you. List of integrals will be provided for each evaluations, and you do not to include them on your lists of equations. 5.11 Marking Scheme The Omnivox LEA system, will be used to calculate and communicate the grades to students. A single marking scheme is used in this class. Table 1. Marking Scheme Lab Reports (3) 15% Logfiles 5% Integrative Activity 5% Quizzes (n-2) 10% Tests (2) 25% Final Exam 40% The Final Evaluation for the course is the final exam. The Mid-Term Evaluation for the course is the first exam of the course plus the first three quizzes of the semester, and the first lab report. All experiment logs, and two of the quizzes, are formative; all other evaluations are summative. 6. Absence during an evaluation Students should be present for all classes and labs, unless there is a serious emergency. A student who is absent for a test, a quiz or a lab must contact the professor as soon as possible by email to notify the absence. Students must also provide a signed medical note to the Professor to justify their absence as soon as they are back to class. The professor may ask the Office of the Registrar to validate the medical note at his discretion. Unless the teacher receives a notification or justification in due time, the absent student gets a mark of zero for the evaluation. Please consult the College s IPESA (all of sections 5.2 and 5.3, pages 17 to 20) for further provisions. 7. Special Needs If you require special accomodations during tests and exam, you should complete a request through the Student Access Center at least a week prior to the test date. Failure to present the request in due time will be met by a rejection, and you will have to take the exam in the same condition as the rest of the class. Exams taken in the Student Access Center must be taken on the same day as the regular exam, in a single seating. The start or end time of the exam must be synchronized with the rest of the class. For example, if you start the exam early, you may not leave before the first section of students finish their seating. Alternatively, you may not start your exam after the first section of students have finished their exam. 8. Plagiarism The College has clear policies on cheating and plagiarism. Academic honesty and integrity is the basis of good ethical science. Students must read the College s IPESA (all of section 5.4, pages 20 to 21) and Course Calendar to clearly understand the definitions of the terms cheating and plagiarism. More specifically, the use of cell phones is strictly prohibited during class. Using any communication device during an evaluation will result in a mark of zero for this evaluation! Cooperation between students during tests or quizzes is strictly prohibited; cases of cheating will be dealt with severely. You may use the internet for research purposes when writing your lab reports. You may even use some figures or pictures from the web. However if you do so, you must state clearly below the image, the website where it was taken from. You must also state clearly in a reference section the list of websites you used in your research. You may not quote or copy
Electricity and Magnetism 5/5 from someone else s work on the internet or elsewhere. In cases where the text in the report is too close to another text, the report (hence all members of the group) will receive a mark of zero. This includes student who share their work with friends. It has happened numerous times that students have shared their work in order to help friends, only to find that the friends had copied part of their report. The result was the same as stated above, and two lab reports, so four people, received a grade of zero, and an administrative note was added to their file to prevent further incidents, as per the guidelines in the Institutional Policy on the Evaluation of Student Achievement (IPESA). 9.
