Electromagnetism 1A

Electromagnetism attempts to describe all electromagnetic phenomena in terms of "fields," namely electric and magnetic fields. In electrical engineering, which is engineering that uses electromagnetic phenomena, it is necessary to correctly understand the phenomena of propagation of electric and magnetic fields in such fields. As the first step, in Electromagnetism 1A, students learn the basic concepts of electrostatic fields from the basics. In particular, Coulomb's law and Gauss's law, which are at the center of the field, are studied. The students will also practice vector analysis as a mathematical tool for this purpose.

In the exercises that follow the lectures, the students will practice applying the ideas learned in the lectures to simple models and solving them numerically in a step-by-step and continuous manner. Through this process, the students will gradually acquire both the mathematical treatment and the physical image used in electromagnetics.

Electromagnetism is a fundamental study that expresses the physical laws of the world, just like mechanics, which you have studied in high school physics. The purpose of this course is to help students understand the basic laws and field concepts of electromagnetism and to be able to visualize actual physical phenomena from the microscopic to the macroscopic level, since it is also the basis of energy conversion devices such as electric devices that you will be studying.

1. As a basic body of knowledge for electrical engineers, the student will acquire a basic knowledge of electrostatic potential and electric field and be able to apply it to simple electrostatic field problems.
2. The student should be able to calculate the vector operations necessary to describe electric fields and be able to perform operations using grad, div, and rot. Understand and apply Gauss's theorem, Stokes's theorem, and Poisson's equation, which are differential laws of electrostatic fields.
3. Understand Coulomb's law and Gauss's law and be able to apply and apply these laws to real problems by learning how to apply them repeatedly.
4. Can calculate the electric field generated by a point charge, line charge, and plane charge, and can find the force received by a charge in the electric field.

Evaluation will be based on exercises, quizzes, and a final exam.
A quiz will be given at the beginning of each lecture (If a student fails to take the quiz, he/she will receive zero points for that session. (However, if there is a valid reason for not taking the quiz, it will not be counted as a quiz.)
The total score will be calculated based on the ratio of 30% for the quiz, 20% for the exercises, and 50% for the final examination, out of a maximum score of 100 points, and a score of 60 points or higher will be considered as passing.
A score of 60 points means 60% of the achievement rate in the achievement objectives 1, 2, 3, and 4.
