David Tong: Lectures on IB Electromagnetism
This is an introductory course on electromagnetism given to second year undergraduates at the beginning of 2015. It assumes a prior knowledge of special relativity. Individual chapters and problem sheets are available below. The full set of lecture notes come in around 120 pages and can be downloaded here. Please do email me if you find any typos or corrections.
