### The Purpose of this Course

This course is a continuation of fundamentals of Electricity and Magnetism I, PHYS 2330.  The principal aim of this course is to continue building the foundation of classical physics that students need in their progress toward the frontier of modern physics research.  The second aim of this course is to strengthen the problem-solving skills of students, which will be invaluable regardless of their future career path.  This course is focused on the extension of electromagnetic theory to magnetism, the understanding of the transient response of passive circuits, and the solution of alternating current circuit problems.  We will finish the course with a discussion of Maxwell’s equations.

## Course Materials

### Required Materials

• Custom courseware available from TopHat (see details below)

### Suggested Materials

• University Physics by H.D. Young and R. A. Freedman – your text from IPS*1500/1510
• Introduction to Electrodynamics, 4th Edition, D. J. Griffiths

## Evaluation

Assessment Weight
Check Your Understanding Questions 20%
Assignments (7 in total, 5% each)  35%
Final Assessment (3 parts, 15% each) 45%

The Check Your Understanding Questions are embedded in the course notes. You get half a mark for completing the question and half a mark for the correct answer. These are conceptual questions that ask you to consider a minor twist on the example problem that precedes the interactive question. The assignments will be a mix of mathematical problem solving, data analysis, and computational problem solving.

### Final Assessment

You will be creating your own personal study guide to summarize the course, which we will divide up into three segments:

1. Current, current density, resistivity, conductivity, Ohm’s law, Lorentz force law, Biot-Savart Law, motion of charged particles in electric and magnetic fields, Ampere’s Law (Lectures 1 to 8) – Due Friday Feb 11th
2. Induction, Faraday’s law, inductors/inductance, energy stored in magnetic fields, capacitance, energy stored in electric fields, capacitors & inductors in DC circuits, transient effects (Lectures 9 to 16) – Due Friday March 18th
3. AC circuits: resonance circuits, filter circuits, Power in AC circuits, force & torque on magnetic dipoles, Magnetic materials, the H field, Displacement current & Maxwell’s equations, EM waves (Lectures 17 to 24) – Due Monday April 18th

Your personalized study guide is a document that you create that can be used in your future studies to remind you of the key concepts and problem-solving strategies that you have encountered this semester. For each of the three sections in the course, you will include the following items:

• Key definitions and terminology
• Relevant equations and diagrams (as necessary)
• Three unique worked examples that illustrate the important concepts (not examples taken from the course notes or the assignments)

## Help

The “lecture” times (Tues/Thurs 10 to 11:20 am) will be used as an open opportunity to ask questions on the materials – lecture notes/problems, check your understanding questions, assignments, personalized study guide etc. If you would like help from either the instructor or teaching assistant at another time, please contact by email to arrange.

The information in the table above is provided as a rough guide in terms of the schedule of material covered during the term.  The indicated weeks in which assignments will be due are also tentative.  Assignments will be posted on the course website, along with the associated due dates.  Check Courselink regularly to stay informed.

Given the current situation with COVID19, this will be a semester that will be highly changeable. We will be working entirely online at the beginning, with the hope of being able to switch to face-to-face, depending on the situation. My plan is to have small, frequent assessments to keep us all on track and communicating, as this will be more challenging without face-to-face interactions. I will not be requiring you to do a midterm or final exam in a proctored fashion. My guiding principles throughout this unusual semester are:

1. Stay connected
2. Be flexible
3. Be kind

## TopHat

We will be using Top Hat for our digital textbook. You will be able to submit answers to in-class questions using Apple or Android smartphones and tablets, or computers. For instructions on how to create a Top Hat account, please refer to the invitation sent to your school email address or consult Top Hat's Getting Started Guide (https://bit.ly/31TGMlw). You will also require Top Hat to access the digital interactive textbook, Electricity and Magnetism, that we will be using in this class.

If you already have a Top Hat account, go to https://app.tophat.com/e/552258 to be taken directly to our course. If you are new to Top Hat, follow the link in the email invitation you received or...

1. Go to https://app.tophat.com/register/student
2. Click "Search by school" and input the name of our school (University of Guelph)
3. Search for our course with the following join code: 552258

The cost of the textbook is $5 and will be applied at checkout when enrolling in our Top Hat course (the lowest I could possibly set it). Bear in mind that textbook material will be made available in our course throughout the semester, so don’t panic if you don’t see any in the course upon entry. Note that you have the option of a one-semester TopHat subscription ($30) or a one-year subscription ($48). If you plan to take Electricity & Magnetism II (PHYS*2340) next semester, the one-year subscription plus the cost of the book (a total of$53) will be a one-time cost for the entire year of Electricity and Magnetism.

## Course Statements

### (Not) Working With Other Students

All work submitted for grading in this course must be each individual student's own work.  While students are encouraged to share thoughts and ideas, it is not acceptable to share assignment solutions.  The “Check Your Understanding” questions, assignments, and personalized study guides are not group projects unless explicitly stated otherwise by the instructor.

### Course Assessment

The Department of Physics requires student assessment of all courses taught by the Department. These assessments provide essential feedback to faculty on their teaching by identifying both strengths and possible areas of improvement. In addition, annual student assessment of teaching provides part of the information used by the

Department Tenure and Promotion Committee in evaluating the faculty member's contribution in the area of teaching.
The Department's teaching evaluation questionnaire invites student response both through numerically quantifiable data and written student comments. In conformity with University of Guelph Faculty Policy, the Department Tenure and Promotions Committee only considers comments signed by students.

Your instructor will see all signed and unsigned comments after final grades are submitted. Written student comments may also be used in support of a nomination for internal and external teaching awards.

NOTE: No information will be passed on to the instructor until after the final grades have been submitted.

## University Statements

The University of Guelph is committed to upholding the highest standards of academic integrity and it is the responsibility of all members of the University community, faculty, staff, and students to be aware of what constitutes academic misconduct and to do as much as possible to prevent academic offences from occurring.
University of Guelph students have the responsibility of abiding by the University's policy on academic misconduct regardless of their location of study; faculty, staff and students have the responsibility of supporting an environment that discourages misconduct. Students need to remain aware that instructors have access to and the right to use electronic and other means of detection.

Please note: whether or not a student intended to commit academic misconduct is not relevant for a finding of guilt. Hurried or careless submission of assignments does not excuse students from responsibility for verifying the academic integrity of their work before submitting it. Students who are in any doubt as to whether an action on their part could be construed as an academic offence should consult with a faculty member or faculty advisor.
The Academic Misconduct Policy is detailed in the Undergraduate Calendar.
