## 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. |

provides us with a straightforward way of calculating the force on a given charge

when the relative position with respect to the source charge is known.

**Coulomb's law**is an example of what is known as an "action at a distance" law. Itprovides us with a straightforward way of calculating the force on a given charge

when the relative position with respect to the source charge is known.
