LECTURES

The main goal of the course is the development of a basic understanding of magnetism, magnetic fields, magnetic force, electromagnetic induction, inductors, AC circuits, electromagnetic radiation, geometrical optics, optical interference and diffraction. Lectures will cover the major topics, emphasizing and discussing the important points. PowerPoint lecture notes will be posted on-line on Angel. Your personal participation is important, and it is critical that you read the assigned material before lecture.

 

HOMEWORK:  There will be one homework assignment per week (see Table below). Homework is due each Friday (at the beginning of the class).

 

Suggestion: You will have about a week to work on homework problems. Don't wait until the last hour to do them. Personally, I found that it is very helpful to attempt the problems even before the material is discussed in the lecture.

 

QUIZZES are optional:  There will be few unannounced quizzes for extra points. Each one is worth 10 points. All extra points will be added to your Exams. Since the quizzes are optional, the missed quiz can not be retaken. 

 

TESTS:  There will be 3-4 Tests during the quarter. On a Test you will get 5-6 problems, similar to quiz problems, homework problems, problems done in class, or problems worked out in the book. In case of 4 tests the lowest grade test will be dropped from your final score. In the case of absence, that are beyond your control, you have to contact me BEFORE the exam to get permission and then you should retake the test. 

 

LABORATORY:  There are five lab sessions and a few smaller activities in this course (see Table below). According to PHOE department policy, in order to pass this course you have to complete all labs and reports and get a passing grade (not less than 70%).

Class Policy

Attendance POLICY:             It is important that you attend all the classes to take maximum benefit of the lectures and classroom activities. If you miss classes it is your responsibility to make sure that you learn the materials before attending the next class.

 

Late homework, or missed quizzes/exams will DEFINITELY, absolutely not be credited for, except in very unusual circumstances. If you are unable to submit any homework on the due date, please do so BEFORE the time.

 

The test dates (weeks) are specified in this syllabus in advance (please, see table below) and will be additionally announced in the class. If it is inevitable that you miss any test, let me know before the date, NEVER after the work has already been missed. If you are sick, I need to have an official call from administration, please.

 

Please note that in the case of cheating, which includes copying homework or laboratory reports, or copying or using unauthorized materials during examinations, it will result in a course grade of " F ", at least. You may consult with each other about homework assignments; however, if you work out a homework problem while watching over someone else’s solution, that will be considered cheating.

Usage of your laptop computer on topics irrelevant to the lectures (checking e-mails, surfing the web, etc) inside the classroom is not permitted. This is very distracting to those sitting next to you. Laptops are not allowed in any examination
