As Taught in:

2018/2019

Level:

Undergraduate

Learning Resource Types:

=> Problem Sets

=> Notes

=> Reading Resources

Course Overview:

102 Electromagnetism is an introduction to electromagnetic fields and forces. Electromagnetic forces quite literally dominate our everyday experience. The reason you do not fall through the floor to the center of the Earth as you are reading this is because you are floating on electrostatic force fields. However, we are unaware of this in a visceral way, in large part because electromagnetic forces are so enormously strong.

In addition to Electromagnetic course to the basic concepts of Electromagnetism, a vast variety of fun topics are covered in this course: Lighting, Pacemakers, Electric Shock Treatment, Electrocardiograms, Metal Detectors, Musical Instruments, Magnetic Levitation, Bullet Trains, Electric Motors, Radios, TV, Car Coils, Superconductivity, Aurora Borealis, Rainbows, Radio Telescopes, Interferometers, Particle Accelerators, Mass Spectrometers, Red Sunsets, Blue Skies, Haloes, Color Perception, Doppler Effect, Big-Bang Cosmology.

Prerequisites:

Physics 101, Calculus

Textbook:

Giancoli, D. C. Physics for Scientists & Engineers. Vol. 2. Prentice Hall.

Collaborative Work:

There will be 36 lectures, 12 problem sets, 1 exam during regular lecture hours, and a week of final.

During final, I expect you to know all material covered in the lectures, the reading assignments, the problem sets, and recitations. 

This subject encourages collaborative teamwork. As you study together, help your partners, ask each other questions, and critique your group homework and lab write-ups.

Please hand-in your work on the due dates. Three problems, randomly chosen, will be graded. Solutions will available on the day after the due dates.

There will be no make-up works! Therefore, teach each other! you can learn a great deal by teaching one another.

Course Notes:

Learners also need the 102 Electromagnetic Readings. This readings contains a number of different materials that learner will need for the course, including experiment write-ups. Learner should bring this reading to class consistently, as it contains a lot of material that will be used in class and handed in.

In addition, we use many visualizations in the course.

If learner feel a need to consult for additional insight or for a different perspective, just about any of the standard introductory textbooks on electromagnetism will do. For your convenience, we reference relevant chapters of the following texts in the summaries:

These texts are expensive, and we strongly advise you to make sure that you are comfortable reading them before you purchase them. 

Reading Resources:

Learner are responsible for reading the Course Readings resources and working assigned problems. Learner will sometimes be assigned homework problems on material that has not yet been covered in class. Learners should start homework early and get help if needed before the due date.

Honesty on Course Work:

Learner are welcome to and encouraged to work on the homework problems with fellow learners. However, the work learner submit should be learner own and reflect learner own understanding of the subject. For in-class work, learner must be present and personally write learner name on any material which is turned-in in that class.

Before Class Reading

There is a short reading assignment which covers the material in the up-coming class. We urge you to read this summary before coming to class.

Written Homework

There will be one homework handed in on paper each sessions. To receive full credit for your hardcopy homework handed in, you must prepare and submit lucid and clearly reasoned written solutions. 

In-class Group and Personal Assignments

In almost all classes, individuals and groups will submit answers to questions about desktop experiments done in class, material covered in the lecture in that class, and so on. Learner must be present in class to receive credit for assignments submitted either by learner or by a group.

Group Work

Learner will be assigned to a group of three for collaborative work. Your group assignment will be announced near the beginning of the term. If learner are not satisfied with the way learner group is working, first try to discuss it with group members. If learner cannot arrive at a satisfactory solution, then discuss the problems with instructors.

Laboratory

Learner will be offered hands-on, inquiry-based activities during the class period. These labs allow you to discover various aspects of a Physics Concept. Labs will vary in length and complexity and will be done in groups.

Evidence of Understanding

Papers and presentations. There will be a final in the course. The final will be a written paper and will cover all of the subject topics that being discussed during the course. 

If paper and presentations does well, then learner can get a chance to have an “A” or “AA”. Once the final course grade has been computed at the end of the term, grades will be assigned as explained in the beginning of “COURSE“
