Outline:
This course is based on Electromagnetics I and II taught in the Electrical and Computer Engineering Department and aims to further enhance and develop the content. Electromagnetics I and II also largely provide university-level lessons, however some parts were either omitted due to academic constraints (related to peripheral basic academic ability, etc.), or simplified by relaxing their stricter handling. However for the Advance Courses, it is desirable to maintain the academic ability for basic subjects like electromagnetics at a university level both in name and reality. Therefore, the course aims to further raise the level while supplementing the content of Electromagnetics I and II.
Style:
The evaluation will be based 100% on periodic exam scores. The pass mark is a score of 60 or more in total for these. Handouts will have content on electromagnetic theory, formulation, and specific computational problems.
Notice:
This course's content will amount to 90 hours of study in total. These hours include the learning time guaranteed in classes and the standard self-study time required for pre-study / review, and completing assignment reports. It is recommend that students have studied Electromagnetics I and II (in years 3 and 4) at our school's Electrical and Computer Engineering Department prior to taking this course.
Students who miss 1/3 or more of classes will not be eligible for a passing grade.

Electromagnetic induction phenomenon
Electromagnetic induction phenomenon is the principle for many kinds of equipment such as generators. However, electromotive force is generated by both the temporal variation of the magnetic flux itself and the relative motion of the conductor to it.
