Lecturer: Masud Haque (email@example.com)
Lectures and Tutorials
The lectures are on Tuesdays, 11:05 PM, Physics Hall, and Fridays, 11:05, Physics Hall.
There are two tutorials every week, with the same content. (You
can attend whichever is more convenient.)
Thursdays, 2:05, Hall A (Arts Block); Fridays, 1:05, Hall C (Arts Block).
The tutor is Adam Tallon. Email: firstname.lastname@example.org
Office: Room 1.6 in the Theoretical Physics Dept.
During tutorials the tutor will discuss solutions to some of the assignment problems.
Problem set 03. Due tuesday February 25th, 5:30PM.
Problem set 02. Due tuesday February 18th, 5:30PM, in MP204 drawer near entrance of Dept.
Problem set 01. Due tuesday February 11th, by the end of the working day (5:30PM), in the MP204 drawer near the entrance of the Theoretical Physics Dept.
Problems 3 and 4 in this problem set involve finding the total
charge of objects from the linear charge density or from the surface
charge density. This will require breaking up the object into
infinitesimal pieces and then adding up the contributions of each
piece, which amounts to an integration. We will have to do variants of
this procedure many times during this module; so please practice until
you are fully comfortable.
The relationship between charge density and total charge is the same as that between the usual (mass) density and total mass. For guidance, you could try
this video, this video, this discussion, these notes.
Material covered in Class
I will point to relevant chapters in
Prof. Nash's Notes and
Vol. II of the Feynman lectures (referred to as Feynman II below).
Of course, equivalent material is available in many other textbooks, or in online material such as those linked to further down on this page.
Continuous charge distributions. In class, we worked out how to calculate the potential and the electric field due to a continuous distribution of charge by first calculating the contribution due to an infinitesimal element and then integrating (``adding up''). This is an important technique which will recur throughout this module; please make sure you are able to set up integrals like this yourself.
Coulomb's Law, Electric Fields,
Chapter 1 of Nash-notes. The introduction to the electric potential
in Nash-notes Chapter 1 Section 3 is more detailed than we had time
for in class; you might want to read this carefully.
In Feynman lectures Vol. II, you will find similar material in the first 4 sections of Chapter 4.
Overview and Background.
In Feynman lectures Vol. II, Chapter 1 gives an overview of what we
will learn this semester.
Chapters 2 and 3 introduces grad-div-curl and vector integration. You are supposed to know most of this material already. Working through them will be a great help for MP204.
Prerequisite: Vector Calculus
This module requires you to be very familiar with Vector Calculus. You should be comfortable with grad/div/curl, Stokes' theorem and the divergence theorem, and of course vector addition and components.
If you need a review, you can try working through some of the following. I strongly suggest making time to do this at the beginning of semester.
Important equations of electromagnetism
Here is a list of the main equations and results we encounter in MP204.
Lecture notes from a previous lecturer
MP204 lecture notes of Prof. Charles Nash --- this is roughly the material to be covered in the module, with some additions. It is recommended that you work through these notes, and in addition spend significant time working through at least one textbook.
There are many, many textbooks on introductory electromagnetism or electrodynamics. You are strongly encouraged to read through one or more textbooks.
In particular, I suggest working through the Feynman lectures (Volume II), which are free to read on this website. The material we will cover in MP204 is mostly contained within the first 20 chapters of Volume II. (Specifically: Chapters 1, 4--6, 13--18, 20.) This will be very close to what we will cover. However, the material is very standard and you will find the same topics in many other texts.
Material available online:
Lecture notes from various places.
Of course, I didn't check in detail for correctness and/or how closely these notes are aligned to the matter we cover in MP204, so please use at your own discretion.
Please let me know if any of the links don't work.
We use SI (also called MKS or MKSA) units. Note that many equations look quite different when written in Gaussian (or CGS) units. When reading a textbook, be sure to watch out for which units that text is using.
Notations vary. I will mostly try using the same notations as in Prof. Nash's notes, but will not always succeed. You anyway need to be able to read and learn from multiple sources using different notations for the same physical quantities.
