# ELECTROMAGNETICS

A good understanding of electromagnetics is a requirement to be successful in any scientific discipline. This book will make you an expert in electromagnetic theory, and help you get a complete understanding of Maxwell's equations. The artistic experiments, the mathematical constructs, and logical conclusions are presented in a step by step, easy to understand manner. The electromagnetic equations are presented first in electromagnetic and electrostatic system of units, and the present SI form of the equations are logically derived from them.
