Summary:

Electromagnetics describes the interaction between electric charges, electric currents, magnetic moments, and electromagnetic fields. An electromagnetic field can be static, slowly changing, or form waves. An in-depth knowledge of electromagnetism will be essential to understand the character of light which is an electromagnetic wave and obey the laws of optics. This volume presents a collection of problems in electromagnetics covering basics and the varied areas of applications of electromagnetic principles
