Course Schedule

Welcome to the home page of Contemporary Physics III. This is your resource page for information about the course, including homework assignments, exams, and solutions. This web page is also the syllabus for the course. To save paper, I will not usually print and distribute copies of documents in class. You may read them on the web or your computer and print out if you need.

Recitations will be on Wednesday 2:00-3:50 p.m. or 4:00-5:50 p.m. in the physics computer lab, Disque 704.

In this final, and most fun of all part of Contemporary Physics, we'll delve into further properties of electricity and magnetism. Topics include

- Magnetic Fields
- Electric Circuits
- Magnetic force (including the Hall Effect)
- Patterns of EM fields (focus on Gauss's Law)
- Faraday's Law
- Electromagnetic Radiation (yeah!)
- Waves and Particles (EM waves are also particles!)

See the course schedule below for the reading assignments. You should do the reading before class so that you are prepared to ask questions about material that you did not understand.

Homework: 30% (2/3 written problem sets and 1/3 computer assignments)

Midterm: 25%

Final Exam: 35%

Class Participation: 10% (Woody Allen said "90% of life is just showing up." In this class you get somewhat less.)

Electronic distractions: Silence your cell phone or leave it home. Only phone calls (to me) from the Nobel Prize committee will be tolerated. Laptop computers may be used only for taking notes. Web surfing, texting, reading/sending email is prohibited during class. I will ask you to leave the class if you violate this rule.

Food, no. Coffee, yes. Maybe small snacks are also OK, but nothing that will tempt me to steal it (triathletes are always hungry!).

Plagiarism: Use your own very large brain (you're a physicist!) and
don't even think about cheating. The usual University rules apply. By
stepping into the classroom, you agree to abide by Drexel's policy on
Academic Integrity

Problem sets will be due at the beginning of class on each Friday (except the first week and week 6 of the midterm). Solutions will be available on the web page on that same day, so late homework will not be accepted. The lowest homework will be dropped (so you're covered for one and only one hungry dog incident or late homework if that's how you want to use it). Please neatly and accurately write up your solutions to these problems.

You may discuss the homework with your classmates, but you and you alone are responsible for the work that you turn in. Please write up your own solutions to the problems and computer assignments. Breaches of this policy will result in homework scores being divided by the number of ``participants.'' Second offenses may result in failure (of the class).

Use of solutions to these problems from previous years or any other source without reference constitutes plagiarism. You must attribute (by giving the correct reference) any significant help that you receive from outside sources.

**Problem Set 1 **(Due in class Friday, April 10):

Chapter 18, problems 41, 59, 60, 64, 68

on current, parameter." You must explain your answers!),
Problems 19.P.42, 44, 70, 71 (also graph the potential V and electron
current i for all at points A-F around the circuit), and 75

**Problem Set 3 **(Due in class Friday, April 24):

Problem Set 6 revised solutions(PDF)

Program assignments will be discussed in recitation, will count as one-third of your total homework grade, and are due at the beginning of recitation on Wednesday in weeks 3, 5, 7, and 9 (see schedule below)

Programming assignment 1 (Due in recitation Wednesday, April 15)

Programming assignment 2 (Due in recitation Wednesday, April 29)

Programming assignment 3 (Due in recitation Wednesday, May 13)

Programming assignment 4 (Due in recitation Wednesday, May 27)

The midterm will be given during recitation in Week 6 (on Wednesday, May 6). If we keep to the schedule, it will cover chapters 18 through 21. An equation sheet will be provided.

The final will be held on Friday, June 12 3:30-5:30pm in PISB 104. It will include material from the entire course, with more weight given to the second half (roughly 30% first half, 70% second half). An equation sheet will be provided.
