This course aims to provide students with an introduction to the principles and behaviours of electric and magnetic systems, and the unified subject of electromagnetism in terms of Maxwell’s four equations. Building on electromagnetic theory, we will analyse a number of problems that are of importance in optical and radiofrequency engineering. Graduate Attributes Developed in this Course – Research, inquiry and analytical thinking abilities – Capability and motivation for intellectual development – Ethical, social and professional understanding – Communication in a scientific/technical context – Collaborative and management skills – Information literacy 2.3 Course learning outcomes (CLO) By the end of this course, you will be able to: Explain how electricity and magnetism are related and unified Use Maxwell’s equations to analyse static and simple time-dependent systems of charge and current distributions. Apply Maxwell’s equations to describe the behaviour of electromagnetic waves for a number of important geometric arrangements. Demonstrate the practical implications of electromagnetic theory in experiments Graduate Attributes Developed in this Course Research, inquiry and analytical thinking abilities Capability and motivation for intellectual development Ethical, social and professional understanding Communication in a scientific/technical context Collaborative and management skills Information literacy 2.4 Relationship between course and program learning outcomes and assessments Course learning outcomes 1-3 are assessed in the 4 assessment tasks. These assessments are largely of a critical-thinking nature designed to determine students’ ability to deploy acquired knowledge to new situations, which is a key graduate attribute for successful university graduates. 4 3.

For details about lab days, times and class codes, see http://timetable.unsw.edu.au/2021/PHYS2113.html or contact Laboratory Staff (Tamara Reztsova at t.reztsova@unsw.edu.au). 3.2 Expectations of students We believe that effective learning is best supported by a climate of enquiry, in which students are actively engaged in the learning process. To ensure effective learning, students should participate in class. Effective learning is achieved when students attend all classes, have prepared effectively for classes by reading through previous lecture notes, in the case of lectures, and, in the case of tutorials or laboratories, have made a serious attempt at doing the problems or pre-work themselves prior to the class. Furthermore, lectures should be viewed by the student as an opportunity to learn, rather than just copy down lecture notes. Effective learning is achieved when students have a genuine interest in the subject and make a serious effort to master the basic material. Academic misconduct will not be tolerated in any form in this course. Substantiated instances of cheating, plagiarism or copying answers may result in a failure grade or significant deduction of marks. Please see 5 http://student.unsw.edu.au/plagiarism if you are in any way unsure of what constitutes plagiarism. Assignments in this class are to be done independently. 4.

Academic integrity, referencing and plagiarism Referencing is a way of acknowledging the sources of information that you use to research your assignments. You need to provide a reference whenever you draw on someone else’s words, ideas or research. Not referencing other people’s work can constitute plagiarism. Further information about referencing styles can be located at student.unsw.edu.au/referencing Academic integrity is fundamental to success at university. Academic integrity can be defined as a commitment to six fundamental values in academic pursuits: honesty, trust, fairness, respect, 7 responsibility and courage.1 At UNSW, this means that your work must be your own, and others’ ideas should be appropriately acknowledged. If you don’t follow these rules, plagiarism may be detected in your work. Further information about academic integrity and plagiarism can be located at: The Current Students site student.unsw.edu.au/plagiarism, and The ELISE training site subjectguides.library.unsw.edu.au/elise The Conduct and Integrity Unit provides further resources to assist you to understand your conduct obligations as a student: student.unsw.edu.au/conduct. 7.
