Sir James Jeans' well-known treatise covers the topics in electromagnetic theory required by every non-specialist physicist. It provides the relevant mathematical analysis; it is therefore useful to those whose mathematical knowledge is limited, as well as to the more advanced physicists, engineers and applied mathematicians. A large number of examples are given
