Course description and aims

In this lecture, we will study magnetostatic as sequel chapter of static electricity studied in Electricity and Magnetism I. After this, we will introduce a concept of temporal variation of electricity and magnetism and study their relations. Density of magnetic flux, Magnetic materials, Electromagnetic induction and Magnetic energy will be explained followed by explaining extended Ampere's law based on a concept of displacement current. Through lectures and excises in this class, basic of Electricity and Magnetism will be mastered.

Student learning outcomes

The following abilities will be mastered through this class
1) Understand and explain force produced by current
2) Understand the equations of density of magnetic flux and explain the meaning
3) Explain behaviors and phenomena by magnetic materials and magnetic circuits
4) Explain the meanings of electromagnetic induction and Lorentz force
5) Explain the meanings of inductance and magnetic force
6) Explain the meanings of displacement current and extended Ampere's law

Keywords

Ampere's law, Magnetic Meterials, Electromagnetic induction, Magnetic energy, Displacement current

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills
・Fundamental specialist skills on EEE

Class flow

Students must submit preparation reports in advance and the reports are evaluated in each class. At the end of each class, students solve some excise problems about the contents of the lecture.
