### Overview

Formulation of the electromagnetism theory is an essential key to our understanding of nature, such as classical optics, microwaves and electric circuits. Both electric and magnetic forces were discovered millennia ago prior to being formulated by Coulomb and Bio-Savart. However, Maxwell showed that electric and magnetic fields are both generated and altered by each other. This revolutionary discovery led to a novel and unique branch of physics, named electrodynamics. In this course, we review several important concepts in the Classical Electrodynamics, among the others, such as Green’s functions, boundary-value problems, multipoles expansions, electrostatic of macroscopic media, magnetostatics, time-varying fields, Maxwell’s equations and gauge transformations, and covariant formulation of classical electromagnetism.

### COMPLETING THIS COURSE WILL HELP YOU:

- Electrostatic and boundary-value problems
- Green functions and determining electrostatic under different conditions
- Multipoles expansions and electrostatics of Macroscopic Media
- Gauges and Maxwell's equations

### Who is the course for?

This course is suitable for physics graduate students that are familiar with electromagnetism. In the current form, Electrodynamics has been developed over the last 150 years, and thus, it is impossible to learn all these developments historically. Therefore, the contents are chosen selectively for the graduate programme by the faculty of science. Note that propagation of EM fields, radiation, and scattering will not cover during this semester.

### MAIN TEXTBOOK

The course will be based on *Classical Electrodynamics* (3rd Edition) by *John David Jackson* (who is a Canadian–American physicist born in London-Ontario). Chapters 1, 2, 3, 4, 5, 6, and 11 of the book will be covered in the winter semester.
