**Welcome** to the Fall 2017 course webpage for **PHYS 3122** (Electro and Magnetostatics) ! This is an advanced undergraduate course introducing a rigourous field-theoretic formulation of classical electromagnetic phenomena in vaccum and matter. Bookmark this page and come often to check for updates. Homework assignments and solutions, lecture notes, and detailed reading assignments for the course will be posted here regularly. We will be using the following textbook: D. J. Griffiths, *Introduction to electrodynamics*, Fourth edition.
