Course description
In the first part, learn the Gauss' theorem and Poisson's equation to understand electrostatic phenomena. Give an understanding on the relationship between electric charge, electric field, and electrical potential. In the second part, learn the relationship between electrical current and magnetic field. Understand that the electric current generates magnetic field, and then magnetic field generates electromotive force.
Expected Learning
1. Solve the equation to obtain electric field using Gauss' theorem.
2. Solve the equation to obtain electrical potential using Poisson's equation.
3. Describe the relations between electric charge, electric field and electrical potential.
4. Describe the equation of force that is exerted to a current or a moving charge in a magnetic field.
5. Calculate the magnetic field using Biot-Savart law
6. Calculate the magnetic field using Ampere's law
7. Calculate the electromotive force in a moving or transforming circuit

Message from instructor(s)
Many students have an impression that the electromagnetic theory is difficult to understand due to frequent use for differential and integral mathematics. However, it is important to give a graphical image of the phenomena before resorting to the mathematical equations.
This subject is indispensable to understand the basic properties of materials and molecules. In addition, the electromagnetic phenomena are found in various aspects of our daily life.
