授業の目的　【英語】
Goals of the Course

This course is a solid introduction to electrostatics and magnetostatics, as well as elementary electro- and magnetodynamics. It covers the first half of the textbook by Griffiths.

NOTE TO INTERNATIONAL EXCHANGE STUDENTS: this course assumes knowledge of vector calculus. We do not have time to reteach the basics that Nagoya University students have already learned. You must have a good grasp of vector calculus to take this course. You must be willing to work hard -- this course is not a holiday in Japan.

By the end of the course, students will have gained an intuitive as well as quantitative understanding of the basic physical principles of electromagnetism, as well as familiarity -- and hopefully mastery -- of some of the fundamental mathematical methods required to solve problems in physics, engineering, chemistry and applied mathematics.

This course has dual aims: 1) to convey physical and mathematical principles relevant to solving applied problems in physics, engineering and chemistry; 2) to improve students’ technical ability – i.e. ability to express intuition in mathematical terms and ability to solve problems.

Unless a prior special arrangement is made with the lecturer, students must be familiar with vector calculus (div, grad, curl; line, surface, volume integrals; etc.) to take this course. Vector calculus is taught in Mathematical Physics II.

Objectives of the Course

The main course objective is to enable students to master each point in the course plan, as outlined below, to the level of the first half of the textbook by Griffiths. Advanced students will gain extra insights into theoretical physics and applied mathematics.

授業の内容や構成
Course Content / Plan

Participants are expected to prepare solutions to problems relating to the lecture course content, which are handed out by the EM lecturer, and present their solutions by projecting them on a screen using MS Teams during the tutorial course (Physics Tutorial IIa).

Course outline.

1. Revision of vector calculus, curvilinear coordinates, Dirac Delta Function.

2. Electrostatics. Coulomb's Law. Continuous Charge Distributions. Divergence and Curl of Electrostatic Fields. Field Lines, Flux, and Gauss's Law. Electric Potential. Poisson's Equation and Laplace's Equation. The Potential of a Localized Charge Distribution. Physical meaning of the Dirac delta function in the context of Poisson's Equation.

3. Work and Energy in Electrostatics. Conductors. Induced Charges. Surface Charge and the Force on a Conductor. The Method of Images: point charge near a conducting plane or sphere, grounded or insulated. Separation of Variables.

成績評価の方法と基準
Course Evaluation Method and Criteria

PhysSci and all other students for whom the tutorial course Physics Tutorial IIa counts towards their graduation requirement:

Attendance and class performance, attitude: 5%; Weekly quizzes or other written assessment: 30%; Midterm exam: 32.5%; Final Exam: 32.5%

Automotive Engineering Students and all other students for whom the tutorial course Physics Tutorial IIa DOES NOT count towards their graduation requirement:

Lecture Course mark: 2/3; Tutorial Course Mark: 1/3.

The Lecture Course mark is calculated in the same way as for PhysSci students.

Conditions for Course Withdrawal

A formal withdrawal form must be signed by the lecturer and submitted to the Student Office by the official withdrawal deadline in May.

A withdrawal request made after the official withdrawal deadline in May will be rejected unless the circumstances are very exceptional.

Students who wish to take this course -- even though it is not compulsory for them -- in order to learn the exciting ideas are welcome.

---------------------------------------------
Criteria for "Fail (F)" & "Absent (W)" grades

The "Absent (W)" grade is reserved for students who withdraw by the official deadline in May. After that day, a letter grade will be awarded based on marks earned from all assessment during the semester.

If Electricity and Magnetism I is NOT A COMPULSORY SUBJECT and the student plans never to take Electricity and Magnetism I in the future, then a late withdrawal request will be considered.

Notice to Students

Plagiarism (e.g. copying solutions that you have found on the Internet) is an act of academic dishonesty. Cheating in exams (e.g. having lecture notes, assignment solutions or online references open on your computer screen during an online exam) is a serious offence. Copying other people's solutions and claiming them as your own is also an act of academic dishonesty. Nagoya University has a strict policy towards academic dishonesty:

"Acts of academic dishonesty are prohibited during exams, for reports and assignments. If acts of academic dishonesty are discovered, you may be subject to discipline, which may affect your ability to graduate on time."

The punishment for serious breaches (such as cheating in an exam or repeated plagiarism despite a warning) is the loss of all grades from all subjects during the semester and cancellation of any scholarships received.

Even if your course is difficult and it is to be expected that you'll find it hard to finish assignments, it is far better that you submit an honest effort than take the dishonest path. Remember, to be on course for a "B" you only need to score over 70% in the assignments -- and if you paid attention in the tutorials, you would have seen nearly all the problems done for you (in my subjects, at least).

There's no excuse for cheating.

Textbook

1. Griffiths, D.L., 2012, Introduction to Electrodynamics, 4th ed., Prentice Hall.

Alternative textbook (HIGHLY RECOMMENDED):
2. Purcell, E.M. and Morin, D. J., Electricity and Magnetism, 3rd Ed., Cambridge University Press

(Students must read Griffiths regularly.)

参考書
Reference Book

1. Leighton, R.B. & Feynman, R.P., Feynman Lectures on Physics (Volume 2), Pearson.
(Highly recommended.)

2. Boas, Mary, Mathematical Methods in the Physical Sciences 3rd Ed., Wiley (2005). (Intuitive and well-explained introduction to much of the basic mathematics students need to master in undergraduate physics, including vector calculus.)

3. Jackson, J. D., Classical Electrodynamics, 3rd Edition, 1998. (Advanced reference.)

Even if at this stage you can’t understand much of the theory in the book by Jackson, you can occasionally “consult Professor Jackson” and understand a page or more, and also look at the fascinating graphs of solutions. You can learn a lot doing even this.

4. Schwinger, Julian, et al. Classical Electrodynamics (Frontiers in Physics) (Advanced reference.)
Advanced students might wish to be challenged by the world view of one of the 20th century's most brilliant minds in the field.

課外学習等（授業時間外学習の指示）
Study Load(Self-directed Learning Outside Course Hours)

This course is part of your training to be a professional researcher. You are expected to revise the lecture notes, read and work through the textbook, and solve assignment problems outside lecture hours. You cannot learn physics by only attending lectures. The exams will consist of questions covering both lecture notes and assignments.

Students must be willing to work hard if they want to achieve a good, internationally competitive level.

Consultation with, or help from, the lecturer is available at anytime online using MS Teams.

授業開講形態等
Lecture format, etc.

Face to face lectures and tutorials are compulsory (other than in exceptional circumstances; e.g. COVID infection). However, in order to record a video of the lecture -- including student interaction with each other and with the lecturer -- the lectures will simultaneously be carried out online using MS Teams. Students are therefore requested to bring their laptop or tablet to the lecture room. Make sure it has a microphone! Bring an electrical cord. For many G30 students, English is a 2nd or even 3rd language, so video recordings are an invaluable learning aid.

Live lectures via MS Teams (face-to-face and online). Before the start of semester students should ensure that they have correctly installed MS Teams using their THERS (国立大学法人東海国立大学機構 ) email account.

NUPACE students should contact Professor John Wojdylo before the start of semester for assistance with installing Teams correctly.

遠隔授業（オンデマンド型）で行う場合の追加措置
Additional measures for remote class (on-demand class)

All lectures will be live face-to-face and online via MS Teams. Face-to-face attendance is compulsory (barring exceptional circumstances such as COVID infection).

A lecture video will be available immediately after each lecture to help with student revision.

The lecturer will be available to answer questions via Teams chat.
