close Course Overview

Course Overview

During the course Electromagnetism I, we analyze several shapes of electric field around a fixed charge, metal and dielectrics, magnetic fields around an electric charge moving in constant velocity, and the magnetic field around the magnetic dipole.

Key Features

In this class, the mechanisms of electromagnetic phenomena in our lives, such as forecasting earthquakes, thunder, electric vehicles, etc., will be introduced and discussed. You may need to understand several laws of electromagnetism such as Coulomb's law, Gauss' law, Ampere's law, etc. The historical background of how each law was developed will be shown and an explanation given of how to easily understand them. The students will deepen their understanding by doing exercises related to each law taught in the class.

Course Aims

The objective of this class is, firstly, to understand how pioneers developed electromagnetics, and secondly to learn how to analyze electromagnetic fields based on mathematics; and thirdly to apply this knowledge to other issues related to electromagnetics.

In this class, you will learn about electric fields around a static charge in any shape, and magnetic fields around a static current.

The goal of this class is as follows:

  • You will be able to understand the physical meaning of electric fields and magnetic fields.
  • You will be able to understand many laws of physics and analyze static electric fields and magnetic fields by yourself.

Course Requirements

This is a compulsory subject.
