(1) Understand and can explain the laws of magnetism.
(2) Can explain the various properties derived from the Maxwell equation.
Outline:
Based on the knowledge of electrostatic fields learned in Electromagnetism I, this course will be focusing on magnetic fields. Afterward, acquire the knowledge of the entire system of electro-magnetism by learning the Maxwell equation, electromagnetic waves will also be taught. There will be quizzes to check students' understanding.
Style:
The first part of classes will be taught in a lecture style to explain the outline. Then, each student will self-study. There will be a quiz at the end.
Notice:
This course requires an active attitude. It's essential to ask questions if anything is unclear during classes. Any assignment that are given must be submitted on time.
Students who miss 1/3 or more of classes will not be eligible for a passing grade.
