AbstractStudents will become familiar with the basic laws and principles of electricity and magnetism such as Coulomb’sLaw, Gauss’ Law, Ampere’s Law, Biot-Savart Law, Faraday’s Law, and Ohm’s Law. Students must then applythese laws to concrete situations such as the motion of charge particles in electric and magnetic fields, thenature of electric and magnetic fields, and the analysis of electrical current and circuits.

2. Place in the program

Physics NYB is the last of three obligatory Ministerial Physicscourses that have to be taken by all students in a Science Pro-gram. Students usually take this course during their thirdsemester and after, or at least concurrently with, Mathemat-ics 201-NYB (Calculus II—integrals). Following a trendestablished in Physics NYC, students are obliged to com-bine many of the concepts and techniques they have learned(principally in Physics, Chemistry, and Mathematics) so asto tackle new kinds of problems and applications that requirea more comprehensive knowledge and set of abilities thanprevious courses. Physics NYB deals with subject matterwhose principles and applications form the basis of our under-standing of an enormous number of fundamental phenomena,practical devices, and widely-used processes that pervade ourtechnological society (see end of this course outline). Since

all science students can be expected to spend most of theirprofessional lives in environments where such phenomena, de-vices, and processes are an integral part of normal operations,it is essential that they acquire a thorough understanding ofthese things and that they be able to apply them to concretesituations.

3. Contribution to exit profileAs described in the Science Program (200.B0), students mustpossess certain attributes upon graduation. To varying degreesin 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 ObjectivesThe course 203-NYB-05 is designed to fulfill the 00US objec-tives: Analyze various situations and phenomena in physicsusing the basic laws of electricity and magnetism, for whichthe performance criteria are:

and social progress.

5. Course Content5.1 Teaching ScheduleWe meet five hours a week. These are divided into threehours of theory and two hours of lab work or problem solving.Problem sessions are organized to develop problem solvingskills and to promote team work. Students are expected tobe in class on time, and to behave themselves in a dignifiedmanner. Attendance is necessary but not sufficient to ensuresuccess. While it is suggested that students spend at least threehours every week to complete the requirements of the course,most students will require close to five hours. It is absolutelyessential that students arrange their schedule to include thisperiod of preparation.

5.2 Teaching MethodThe course will be presented using a mix of active learningactivities, lectures, in-class problem solving, laboratory exper-iments and demonstrations. Laboratory periods will be usedfor experiments as well as class tests and lectures.

5.3 TextbookThe textbook used in this course, is free open source text fromOpenStax called University Physics developped by Rice Uni-versity. (https://openstax.org) This three volumetextbook will be used this semester as a primary reference.Sections will be assigned for reading before a topic is dis-cussed in class, and problems will be assigned from this text-book. You are expected to come to class prepared, having

Electricity and Magnetism — 3/5

read the assigned sections, and to solve all assigned problemsbefore the quizzes and tests.

All lab experiments, problem sessions, and other relevantdocuments and information, are available on your class web-site (www.remipoirier.com). It is your responsibility todownload and print the documents BEFORE class.

5.4 Problem SolvingThis should become your mantra; solve problems... solveproblems... This class is problem-solving oriented. I wish tosee if you are able to translate a written problem into mathe-matical notation, and solve it using the techniques learned inclass.

A list of suggested problems from the end of chapterproblems in the textbook, will be made available through theclass website. It is the student responsibility to practice allsuggested problems before the test.

5.5 ExperimentsPhysics is an experimental science, and as such, experimentsare of paramount importance to this class. The lab componentof the course is divided into two sections: Lab Reports andExperiment Logs.

5.5.1 Lab ReportsThere will be three (3) evaluated lab reports during the semester,they must be typed using a software such as, LibreOfficeWriter or Microsoft Word. Graphs must be computer gener-ated, using Libre Office Calc, or Microsoft Excel. Equationsmust be typeset in the text with an equation editor. Furtherdetails regarding the format and content of lab reports willbe given during the first lab session and are provided in yourwebsite (www.remipoirier.com).

Deadlines Formal lab reports must be submitted within twoweeks using the Omnivox system. Late lab reports will beaccepted with a penalty of -10% for the next day, and -25%for the day after the next. Lab reports submitted later thantwo days after the deadline receive a grade of zero for all thestudents of the group, even if they have attended and partici-pated in the lab. The same penalty schedule will be applied toany homework that needs to be submitted for evaluation.

Electronic Format The lab reports will be submitted elec-tronically in PDF, ODT (libreOffice), or DOCX (Microsoft-Word) format. Apple Pages documents are not accepted asthey are not compatible with the evaluation software used;install and use LibreOffice instead. It will be your respon-sibility to make sure the documents are complete, and thatall parts, including equations and graphs, display correctlybefore you send it for evaluation. Reports submitted in thewrong format will not be accepted. It is imperative that youwrite lab reports in proper English. Poor English leads to alack of clarity that negatively affects your grade.

5.5.2 Experiment LogsDuring 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 differentformats and are submitted either immediately at the end ofthe lab period, or after a few days following the lab. Furtherdetails regarding the format and content of the experimentlogs will be given during the lab session and are provided inyour website.

5.6 QuizzesQuizzes will be scheduled at roughly weekly intervals, through-out the semester, except when a test is scheduled. At the end,the two (2) worst quizzes will be discarded.

5.7 TestsThese are 100-minutes tests, held during a lab period, requir-ing the solution of harder problems. There will be two testsduring the semester: the first one held on February 26, thesecond one on April 22. These dates are subject to change;any change will be posted on the class website.

5.8 Integrative ActivityAs required by the Science Program, an integrative activity(IA) in which you must integrate the physics concepts dis-cussed in this class with concepts related to other scienceswill be held at the end of the semester. This IA, will be anessay on a science topic. More information will be providedin class regarding this topic. If you have previously done anintegrative activity in physics, you must do another one on adifferent topic for this class.

5.9 Final ExamA three-hour final exam will be held during the official finalexam period. The final exam will consist of two sections cov-ering 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 thefinal exam is to evaluate your overall understanding of theconcepts presented in the course.

5.10 List of EquationsFor the Tests and Final Exam, a list of equations will notbe provided by the teacher. On the other hand, you will beallowed to bring one sheet of handwritten equations. Thislist must be letter sized (8.5 x 11 inches squared) only con-tain mathematical equations, physical constants, and physicsequations relevant for the topics under evaluation. The teacherwill not provide additional information to you if you havenot made a complete list of equations. Full solutions ofproblems, derivations of equations or diagrams are notwelcome on the equation sheet, and the teacher may removethe list if you included any of those on the sheet. The equationsheet will be picked up with the test and will not be givenback to you; you will therefore have to make three lists ofequations during the semester: one for each of the tests andone for the final exam. During quizzes in class, the relevantequations and physical constants will be provided for you.List of integrals will be provided for each evaluations, andyou do not to include them on your lists of equations.

5.11 Marking SchemeThe Omnivox LEA system, will be used to calculate andcommunicate the grades to students. A single marking schemeis 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. TheMid-Term Evaluation for the course is the first exam of thecourse plus the first three quizzes of the semester, and the firstlab report. All experiment logs, and two of the quizzes, areformative; all other evaluations are summative.

6. Numerical gradesEvery time a problem is graded in order to evaluate theachievement of the 00US Objective (see section 4), the follow-ing marking scheme will be applied. The numerical value inthe following table represents a proportion of the total valueof the problem, and the same marking scheme will be usedwhether the problem is graded on 5 or 10 points.

Table 2. Numerical grade

Perfect Solution 100%

Unit absent or wrong, one conversion or signmistake only 90%

One mistake in the mathematical solution 80%

Major or multiple mistakes in themathematical solution, but there is no physicsmistake in the solution

60%

A mistake in the application of the physicsconcepts 40%

Multiple mistakes in the application of thephysics concepts. 20%

Too many mistakes or the solution is notappropriate for this problem. 0%

7. Absence during an evaluationStudents should be present for all classes and labs, unlessthere is a serious emergency. A student who is absent fora test, a quiz or a lab must contact the professor as soon aspossible by email to notify the absence. Students must alsoprovide a signed medical note to the Professor to justify theirabsence as soon as they are back to class. The professor mayask the Office of the Registrar to validate the medical note athis discretion.Unless the teacher receives a notification or justification in duetime, the absent student gets a mark of zero for the evaluation.Please consult the College’s IPESA (all of sections 5.2 and5.3, pages 17 to 20) for further provisions.

8. Special NeedsIf you require special accomodations during tests and exam,you should complete a request through the Student AccessCenter at least a week prior to the test date. Failure to presentthe request in due time will be met by a rejection, and youwill have to take the exam in the same condition as the rest ofthe class.

Exams taken in the Student Access Center must be takenon the same day as the regular exam, in a single seating. Thestart or end time of the exam must be synchronized with therest of the class. For example, if you start the exam early, youmay not leave before the first section of students finish theirseating. Alternatively, you may not start your exam after thefirst section of students have finished their exam.

Accommodation for the final exam works exactly the sameas other evaluations, except that you will start the exam inthe gym with all other students. A space will be reserved foryou in front of the row. After two hours, your professor willbring you to the student access center for the remainder ofthe allocated time. This will insure that I can answer all yourquestions during the first two hours of the exam.

9. PlagiarismThe College has clear policies on cheating and plagiarism.Academic honesty and integrity is the basis of good ethi-cal science. Students must read the College’s IPESA (all ofsection 5.4, pages 20 to 21) and Course Calendar to clearlyunderstand the definitions of the terms cheating and plagia-rism.More specifically, the use of cell phones is strictly prohibitedduring class. Using any communication device during anevaluation will result in a mark of zero for this evaluation!Cooperation between students during tests or quizzes is strictlyprohibited; cases of cheating will be dealt with severely.You may use the internet for research purposes when writingyour lab reports. You may even use some figures or picturesfrom the web. However if you do so, you must state clearlybelow the image, the website where it was taken from. Youmust also state clearly in a reference section the list of web-sites you used in your research. You may not quote or copyfrom someone else’s work on the internet or elsewhere. Incases where the text in the report is too close to another text,the report (hence all members of the group) will receive amark of zero.This includes student who share their work with friends. Ithas happened numerous times that students have shared theirwork in order to help friends, only to find that the ”friends”had copied part of their report. The result was the same asstated above, and two lab reports, so four people, received agrade of zero, and an administrative note was added to theirfile to prevent further incidents, as per the guidelines in theInstitutional Policy on the Evaluation of Student Achievement(IPESA).
