## Electromagnetic fieldsThis revised edition provides patient guidance in its clear and organized presentation of problems. It is rich in variety, large in number and provides very careful treatment of relativity. One outstanding feature is the inclusion of simple, standard examples demonstrated in different methods that will allow students to enhance and understand their calculating abilities. There are over 145 worked examples; virtually all of the standard problems are included. |

The term in the parentheses of (21-30) is clearly the total charge density written

as the sum of the free and bound charge densities as we found in (10-38).

Similarly, the term in parentheses of (21-33) represents the total
