Electromagnetism
Lectures on Theoretical Physics, Volume 2
There are four forces at play in the universe. Gravity acts on the very biggest scales, and the two nuclear forces act on the very smallest. For everything in between, there is electromagnetism.
The exercises below have been created and curated over many decades by members of the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge. The faculty have long had a generous policy of making these examples sheets (and indeed exam questions) publicly available. These questions are taken from a second year course called Electromagnetism, and a third year course called Electrodynamics, together with a first year course on Vector Calculus.
PDFs of the examples sheets can be downloaded below.
