Outline and Purpose of the Course	With the wide-spread of mobile communication, humans are now exposed to electromagnetic fields severely. As today's society is based on various electromagnetic phenomena, it has become a necessity to understand electromagnetics for all. This course focuses on the philosophical view of different physical laws to enrich the understanding of electromagnetics and communication. We will learn that all the complex phenomena found in the universe consist of some basic laws. We will try to understand how these basic laws work using several experiments and illustrations. We will learn different applications of electromagnetism in our lives. We will also learn about harmful electromagnetic radiation. On our journey toward understanding electromagnetism, we will learn that the universe is more mysterious than we thought.
Course Goals	- To understand electricity and magnetism - To understand different features of wave and its role in communication - To be able to explain various natural phenomena and - To understand the role of electromagnetic in modern society and the importance of being aware of electromagnetic radiation

Evaluation Methods and Policy	The evaluation will be based on assignments (20%), mid-term examination (30%) and term-end examination (50%).
Course Requirements	None
Study outside of Class (preparation and review)	The students are encouraged to participate in discussion with others within and outside the class. Sample programs written in Python will be provided. Students are encouraged to play with the programs to visualize how the basic rules work.
References, etc.	The lecture series by the legendary physicist Richard Feynman will form the base of the course. A few related topics will be selected and presented by graphical illustrations to focus on the philosophical view.
