전하/전류가 만들어내는 전기장/자기장에 대해서 배우고, 그에 따른 역학과 에너지 관계를 배운다.

The course is aiming to provide a basic knowledge of the electromagnetism from electrostatic in vacuum, conductors, and dielectrics; magnetostatics in vacuum and in linear/nonlinear media. Also basics of electrondynamics including Faraday's law and Maxwell's equations will be discussed.

Electromagnetic Fields by Roald K. Wangsness
Lectures on Physics Vol. 2 by Feynman, Leighton, and Sands
Mathematical Methods for Physicists (5/e) by Arfken and Weber

1. Vector analysis (3.5 lectures)
The mathematical apparatus that we will use in our discussion of electromagnetism is introduced

2. Electrostatics (4.5 lectures)
Starting with the definition of the electric field obtained from Coulomb's law, we develop the theory of electrostatics, by straightforward application of vector field theory.

3. Potentials (5 lectures)
The best approach to a large class of problems in electrostatics involves solution of the linear, second-order differential equations in the electrostatic potential V, Laplace's equation and Poisson's equation, subject to certain boundary conditions.

Midterm Exam

4. Electrostatic Fields in Matter (5 lectures)
The expansion method for electric multipole moments? is used as a bridge to the theory of the electrostatic field and potential in dielectric matter.

5. Magnetostatics (5 lectures)
Starting from the empirical Lorentz force law and Biot-Savart field law, we develop the theory of magnetic fields from steady currents.

6. Magnetostatic Fields in Matter. (4 lectures)
Of the three forms magnetism takes in matter, we will discuss two: paramagnetism, which is the analog of linear electrostatic polarization, and diamagnetism, which can be treated semiclassically even though it is a quantum mechanical phenomenon.
