Quizzes As we go through the course, I will double box material you should know/memorize. There will generally be daily quizzes on any material that has been double boxed. There are no makeups – but, I’ll drop the bottom 5 quizzes.

Approximate Test Dates There will be 3 tests on Friday, Oct. 4th, Friday, Nov. 1st and Wednesday, Dec. 4th

Final Exam Schedule Phys 235B: Monday, Dec. 16th at 1:30 PM

Absence Policy Your attendance in class is expected, unless you are ill. Please let me know in advance by email or phone call if you will miss class.

Homework There will generally be weekly assignments, due by the beginning of class. There will typically be two components to the assignment, an online component and a written component. For the online component (via ExpertTA): PHYS 235-B (Fall 2019) Intro Physics E&M with Dr. Paul Harper Student Registration Link: http://goeta.link/UST24MI-58D531-1ZC

For the written component: Generally the written assignments will consist of two problems, one completed on one side of paper and the second on the other side of the paper. On the front page of the paper should be your name, section (Phys 235B) and assignment number. Because there will typically be only two written problems, it is expected that they will be clearly laid out in detail, with all relevant diagrams, equations, and algebra shown. Written homework handed in after the start of class on the day it is due is late, and will be graded on a 75% credit basis. After a graded written assignment is passed back, the answer key will be posted on Moodle and/or Google. Needless to say, homework will not be accepted after the answer key is posted.

Student Learning Objectives Students should be able to…. 0) Understand and solve problems for the physics topics listed in the course outline 1) Determine electric and magnetic fields from charge and current distributions. 2) Find the forces that electric and magnetic fields exert on charges and currents. 3) Know Faraday’s law, Lenz’s Law and how to apply them. 4) Analyze D.C. and A.C. circuits. These objectives will be assessed via homework problems, tests, labs and a final exam.

Course Practices 1) Lecture 2) Peer discussion and instructor followup 3) Homework 4) Exams and Quizzes

Students with Disabilities Calvin College will make reasonable accommodations for a student with a documented disability. You should notify a disability coordinator in the Center for Student Success (located in Spoelhof College Center 360) in order to arrange your accommodations. Then, come and talk to me within the first two weeks of class so we can put your accommodations in place

Academic Honesty Students are responsible for acting in accordance with the Calvin College Student Conduct Code. Academic dishonesty on the part of a student will result in a severe grade penalty (possibility a failing grade in the course) and may jeopardize the student’s enrollment status at Calvin.

Electronic Items Please keep all electronic items (computers, tablets, cell phones, etc.) turned off and stowed away (pocket or backpack).

Changes to Syllabus It is understood that the instructor reserves the right to change the syllabus during the course. Nonetheless, I don't anticipate any major changes.

How to study physics 1) Skim the chapter to be covered in lecture ahead of time. Pick out the key points. 2) When a formula is double boxed in lecture, commit it to memory that day. That is, know the formula, what each variable stands for, the units for each variable and have in mind a physical example of the formula (i.e., a sample problem involving the formula). This is helpful for multiple reasons: a) Knowing the formulas allows you to better follow what happens in the classroom. b) Knowing the formulas will help you do the homework. If you have a physical picture of what a formula means and can be used for, it will guide you in how to start and do the homework problems. c) Later work builds on the fundamentals. If you know the physics formulas well for electric fields, it will give you a frame work for understanding magnetic fields. d) You’ll need to know these formulas for the tests and labs. e) You’ll use these formulas and more advanced versions in subsequent engineering and physics classes. f) These formulas really describe the physical world; if you want to understand and use electrical and magnetic phenomena, they’re an essential framework to build from. 3)

“What I cannot create, I do not understand” – Richard Feynman, Nobel Laureate in Physics If you can’t start from a problem in notes and solve it on your own (i.e., without notes or text), you don’t fully understand it (yet). 4) Read through the chapter. 5) Do the homework problems. a) Try to do the problems without referring to the notes or text at first. b) If, after a few minutes, you’re stuck on a problem, think about what it is that you need to proceed. Then, go look for information in the notes and text, find out what was missing, make a note of it, and return to working on the problem without the notes or text. c) It’s often good to work on problems with friends. d) Use plenty of space for each problem and organize your work neatly. e) When you get your homework back, look it over and make certain you understand any corrections. f) As per tip#3, you don’t understand it until you can do them completely on your own. 6) Study for the tests well in advance. a) As per #3, you don’t understand physics until you can do the problems completely on your own. b) You have multiple resources to help you study: your notes, the text, classmates, older students who have taken the course, help sessions, answer keys, tutoring (if needed) and, of course, your professor!...
