| 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. This course is a part of physics courses classified as specialized basic subjects in the Department of Applied Chemistry. |

| 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. |
