#### Textbook (Required)

Electromagnetic Field (Second Edition)

by Roaldk K. Wangsness

John Wiley & Sons, Inc. 1986

ISBN 0-471-81186-6

#### Course Description

The course covers the textbook Chapter

**Part 1:** 1. Vectors, Chapter 2 Coulomb's law, Chapter 3 The electric field, Chapter 4 Gauss's law, Chapter 5 The scalar potential, Chapter 6 Conductors in electrostatic fields, Chapter 7 Electrostatic energy, Chapter 8 Electric multipoles, Chapter 9 Boundary conditions , Chapter 10 Electrostatic in the presence of matter , Chapter 12 Electric current;

**Part 2:**Chapter 13. Ampere's law; 14. The magnetic induction, 15. The integral from of Ampere's law, 16. The electric field, 17. Faraday's law of Induction, 18. Magnetic energy, 19. Magnetic Multi-poles, 20. Magnetism in the presence of matter, 21. Maxwell's equations, 22. Scalar and Vector potential, 24. Plane waves, 25. Reflection and fraction of plane waves, 26. Fields in bounded regions.

These parts have important applications and are the core of modern physics.

#### Course Objectives

To gain basic knowledge, and understand the main principles, of the elctromagnetic field and their applications to specific areas. Students will learn how to find the solutions to specific questions by applying the electromagetic principles and equations. Students will be able to understand and derive important laws, including

- Coulomb's
- Gauss' Law
- Ampere's Law
- Faraday's Law of Induction
- Magnetic energy
- Maxwell's Equations.
- Plane waves
- Reflection and refraction of plane waves

#### COURSE REQUIREMENT AND METHOD OF EVALUATION

1) Students are expected to attend class and participate by asking questions and answering questions raised by the instructors. Class attendance takes 10% of the total grade.

2) The homework assignments and quizzes make up 40% of the total grade.

3) There will be one** midterm** (20%) and one **final exams** (worth 30% of the total grade). Mark your calendar with the exam dates. You are responsible for being there on time. If you have a religious holiday conflict, let me know during the first week of classes. During an exam you must avoid looking at the work of others.

#### Grading Criteria

The grade distribution will be as follows.

A 88% and higher

B 72-87%

C 55-71%

D 41-54%

F 40% and below

We use the +/- system so in each range (no A+), the low end will be minus and the high end plus.

#### HOMEWORK

1) Homework will be assigned once a time per chapter, and will be turned in one week late brfore it is due.

2) Homework solution will be posted below and replaced before next homework is due. Please download it and check your answers if you have any question to your answers.

**Homework Solution:**

Chapter 13 and 14 , Chapter 15 , Chapter 17 , , Chapter 18

#### Important Dates of Exams

**Midterm Exam**:

**Final Exam** :
