: The book features over 900 problems (with solutions for odd numbers) and worked examples in every section to help master the "del operator" and Maxwell's equations. Purchasing Physical Copies

: Certain proofs, such as those for magnetic dipoles, have been described as more laborious than necessary for introductory learners.

If you cannot find Shadowitz, consider Electricity and Magnetism by Edward M. Purcell. Purcell also uses the relativistic approach to derive magnetism. In fact, Shadowitz was heavily influenced by Purcell’s Berkeley Physics Course. Purcell’s book is in print, cheap (via Dover), and available as a legal PDF.

Shadowitz’s book begins with a revolutionary idea: Not a mathematical trick, not an "action at a distance," but a physical entity. Elian explained it using his workshop.
