Unit description Unit description
The theory of electromagnetism, one of the most successful and most widely applied theories of modern physics, describes the properties and behaviour of electric and magnetic fields and their interaction with charged matter. This theory underlies all of modern optics, telecommunication and electrical engineering, and has played an important role in furthering our understanding of the fundamental forces of nature.
The basic laws of electromagnetism are introduced in this unit, and their important consequences and applications in electrostatics, magnetostatics and electrodynamics are studied. It is also shown how these laws can be re-expressed in terms of the more powerful mathematical language of vector calculus, which leads to the development of Maxwell's equations. These equations give a fully unified description of electromagnetism in both static and dynamic situations. The overwhelming success of these equations in describing electromagnetic phenomena is illustrated by studying electric and magnetic fields in matter, and electromagnetic waves. More advanced techniques of experimental physics including indirect measurement of microscopic quantities are covered in weekly guided laboratory sessions, as are further data analysis techniques and regular report writing.

These will be discussed in the Tutorials, and a 15-minute quiz related to the previous week's tutorial questions will also be completed each week during the tutorial. The best 7 quiz marks out of a possible 11 marks will contribute 20% to the final grade. 

Satisfactory performance in quizzes is a hurdle requirement. You must obtain a mark of at least 40% in at least 7 out of the 11 scheduled quizzes to pass the unit. No additional quizzes will be offered for those who fail to meet this requirement.  


On successful completion you will be able to:
  • Understanding and skill in differential and integral calculus with scalar and vector fields in cartesian, spherical, and cylindrical coordinates.
  • Understanding of and a facility for solving problems involving electric fields in the vacuum.
  • Ability to use symmetry arguments to derive electric and magnetic fields from various configurations of charges and currents.
  • Understanding of and a facility for solving problems involving time dependent electric and magnetic fields.
  • Understanding and applying thermodynamic principles to describe physical systems and solve quantitative and qualitative problems concerning thermodynamic systems.

Final Examination (3 hours)

Due: University Examination Period
Weighting: 45%

The final examination is a hurdle requirement. You must obtain a mark of at least 40% to pass the unit. If your mark in the final examination is between 30% and 39% inclusive then you will be a given a second and final chance to attain the required level of performance.

You are expected to present yourself for examination at the time and place designated in the University Examination Timetable.  The draft timetable will be available approximately eight weeks before the commencement of the examinations and the final timetable approximately four weeks before the commencement of the examinations.  Exam timetables are available at http://www.timetables.mq.edu.au/exam.

If you do not sit the final examination at the designated time due to documented illness or unavoidable disruption, you may wish to consider applying for Special Consideration. Supplementary Examinations will be scheduled after the conclusion of the official examination period.

It is Macquarie University policy not to set early examinations for individuals or groups of students.  All students are expected to ensure that they are available until the end of the official examination period.

The final examination will include material from both halves of the unit, with more emphasis on the material taught in the final 6 weeks of the unit.


On successful completion you will be able to:
  • Understanding and skill in differential and integral calculus with scalar and vector fields in cartesian, spherical, and cylindrical coordinates.
  • Understanding of and a facility for solving problems involving electric fields in the vacuum.
  • Ability to use symmetry arguments to derive electric and magnetic fields from various configurations of charges and currents.
  • Understanding of and a facility for solving problems involving time dependent electric and magnetic fields.
  • Understanding and applying thermodynamic principles to describe physical systems and solve quantitative and qualitative problems concerning thermodynamic systems.

Laboratory reports

Due: Week
Weighting: 20%

Laboratory work will begin in week 2 . Students must bring a laboratory notebook to the first class. Lab notes for each experiment will be provided in the lab. Each experiment is allotted two weeks for completion and you are expected to complete 5 experiments. 

You must keep a laboratory  notebook, in which you keep a record of all activities.  In addition you will be required to write a full report on one experiment of your choice.  Some notes about laboratory log books and report writing are included in an appendix at the end of this outline.

The purpose of the laboratory work is to expose you to a range of physical concepts and experimental techniques which spread beyond the coverage of the lectures.  In addition we hope that your ability to maintain a written record of your laboratory work and to write reports on your work will develop further.  To this end, the laboratory will be assessed in the following way:

(i) Your laboratory notebook will be marked each fortnight.  If it is less than satisfactory, it will be returned to you for correcting, and then re-marked.  All relevant calculations must be done, the appropriate graphs drawn, and uncertainties assessed where appropriate.

(ii) You are required to submit a full report on one two-week experiment of your choosing from the first three experiments that you have completed.  This report will be submitted in draft form initially.  It will be marked and returned to you with comments for its improvement.  When the report is resubmitted, your first attempt should also be handed in for comparison.  The mark awarded for the report will be that obtained in the second marking.  (However, if you obtain more than 7 out of 10 for the initial submission, then handing in the final version is optional.) This strategy gives you the opportunity to use the feedback from staff to help you develop professional report-writing skills before your work is finally graded.

The draft report is to be submitted by the end of week 9 with the final version by the beginning of week 13.

Permission may be granted for late submission of laboratory reports if the request for consideration is made prior to the due date.  Reports submitted late may be subject to a marking penalty of one-half mark (out of ten marks) for each working day that the report is late, unless a valid, extraordinary, substantiated reason for late submission is presented to the Unit Convenor.

An increasing number of students are choosing to submit laboratory reports in word-processed form.  This is a good procedure, however there are some points which need to be kept in mind.  If you are not accustomed to using a word processor, the process can take much longer than writing a report by hand.  In addition, problems with hardware can arise which cause delays and frustration.  As a general rule we are not sympathetic to late reports caused by computer faults. 

If you are planning to word-process your report it may also be advisable to bring a memory stick to the lab sessions.  Some experiments have data recorded on PCs which can be saved direct to your memory stick, then included in your report.

The relative weighting of the components of the laboratory assessment will be

Laboratory log book 14%

Report 6%

TOTAL 20%

Satisfactory completion of laboratories is a hurdle requirement. You must obtain a mark of at least 40% in the laboratory activities to pass the unit. If you miss or fail an activity, you must within two weeks arrange a new time to perform the activity. 


On successful completion you will be able to:
  • Understanding of and a facility for solving problems involving electric fields in the vacuum.
  • Understanding of and a facility for solving problems involving time dependent electric and magnetic fields.
  • Understanding and applying thermodynamic principles to describe physical systems and solve quantitative and qualitative problems concerning thermodynamic systems.
  • Developing experimental physics skills in setting up and safely operating laboratory equipment to perform specific measurements, and analysing and interpreting the results of the experiments in the context of discipline knowledge.

Mid-semester assignment

Due: Week 8
Weighting: 15%

A mid-semester assignment based on the first 7 weeks of material in the unit will be announced during Week 6. It will be due in week 8 after the midsemester break.


On successful completion you will be able to:
  • Understanding of and a facility for solving problems involving electric fields in the vacuum.
  • Ability to use symmetry arguments to derive electric and magnetic fields from various configurations of charges and currents.
  • Understanding of and a facility for solving problems involving time dependent electric and magnetic fields.

Teaching and Learning Strategy

The first part of PHYS202 concerns Electromagnetism.  Although we will be following the text by Griffiths, this material is fairly standard and many texts cover it.  The actual physics will not be new to you; it has been covered in previous physics units.  What will be new are the mathematical methods used to describe it - in particular vector calculus.

In the text by Griffiths, chapter 1 gives an outline of vector calculus.  This unit will cover a large part of the material in chapters 2,  5, and 7 and selected topics from chapters 4, 6 and 9 of the text.

The second part of PHYS202 concerns Thermodynamics. Carefully defining temperature, heat, energy, and entropy, we will explore the implications of the first and second laws of thermodynamics. In particular, we will apply thermodynamic concepts to the processes in heat engines and to the modeling of internal energy, enthalpy, the Helmholtz function and the Gibbs function.

In the text by Blundell and Blundell, we will concentrate on chapters 1 and 2, chapter 4, chapters 11, 12, 13, 14, and chapter 16.   

NOTE: To succeed in this course you will need to do many practice exercises from the textbooks and the tutorial questions. You are encouraged to work on the tutorial questions in advance of the tutorials to make the best use of the tutorial time for feedback. This will help build intuition for the physical concepts and skill in the mathematics involved.  If you are comfortable with solving the tutorial and end-of-chapter textbook problems independently then you should perform well in the mid-semester and final exams.
