The study of effect(electric and magnetic fields) of charges at rest and charges in motion.
The Electromagnetic force is one of the four known fundamental forces of nature
All theory of electrical engineering is based on electromagnetics

Introduction 22
Wireless communications systems require antennas To better understand modern communications and
computer systems. To be able to design and analyze electromagnetics-
based devices
Why Electromagnetics is difficult?Why Electromagnetics is difficult?
Introduction 23
Because Electric and Magnetic Fields are three-dimensional are vectors vary in space as well as time are governed by PDEs
As a result Solution of electromagnetics problems requires a high level of abstract
thinking – which is an ability to think three dimensionally in space.It is not possible to solve them by finding the right formula in which to plug the numbers.
Students must develop a deep physical understanding of wave propagation mechanisms where math becomes a powerful tool rather than a crutch
