Welcome to Physics 220

What will we study? Electricity and Magnetism Why? To Graduate

Course Website Note three things in particular: 1.Course Outline 2.Class Schedule 3.PPT Slides

Course Objectives The official course objectives are: 1.Solve problems and answer conceptual questions involving electromagnetic energy (potential), forces, and the motion of charged particles and dipoles. 2.Use Maxwell's equations to find electric and magnetic fields in symmetric arrangements of static charges and steady currents. Also find electric and magnetic fields by integrating over charge and current densities. 3.Analyze simple direct current and alternating current circuits of resistors, inductors, capacitors and power supplies. 4.Use Maxwell's equations to solve problems and answer conceptual questions with changing electric and magnetic fields, including induction and electromagnetic radiation.

Course Objectives By the end of the semester, you should: 1.think more like a physicist; that is, be able to interpret the world around you in terms of abstract models. 2. have a greater appreciation of the beauty and symmetry of physical law. 3. understand the fundamentals of DC and AC electrical circuits. 4. be able to describe several applications of electromagnetic theory to real-world devices. 5. be able to explain how electrical and magnetic phenomena can be understood in terms of the thread model and in terms of the field model.

Course Objectives By the end of the semester, you should: 6. be able to write down the integral and differential forms of Maxwell’s Equations and explain what each equation means. 7. be able to find the electric and magnetic fields of a few fundamental configurations of stationary and moving charges. 8. be able to explain what electromagnetic radiation is, what causes it, and why it is important in our society.

Is Physics 220 difficult? There are many concepts. Many concepts are abstract. Many concepts are interrelated. There’s a lot of calculus – but we’ll review calculus as we need it.

How much time will it take? Plan on at least 2 hours outside of class for each hour in class.

What’s the difference between Section 1 and Section 2? They’re the same… You can attend either section as you wish Clicker quizzes taken in either section will count.

Will I get a good grade? Percentiles Letter Grade 85 – 100 A 67 – 85 A– 50 – 67 B+ 36 – 50 B 22 – 36 B– 14 – 22 C+ 10 – 14 C Most students who put forth a genuine effort will do reasonably well.

Will I get a good grade? A word of warning: Some students do not receive as good a grade as they are used to, even if they work hard.

Homework Submitted online Interactive Immediate feedback Due every Thursday at 11:55 p.m. Printable versions are available Tutorial Lab is in N-304 ESC

Mastery Checks Submitted online Similar to quiz and test problems Open book Some helps available Helps you identify weaknesses and misconceptions Due Saturday at 11:55 p.m.

Quizzes Submitted online Similar to test problems Closed book Please don’t discuss questions! Due Saturday at 11:55 p.m.

Basic Tests Practice Basic Tests No credit questions Covers basic concepts Single concept, simple questions Take as often as you’d like

Basic Tests No direct credit 10 questions randomly chosen from the Practice Basic Test No books, notes, web materials! Timed “Pass” if 9-10 are correct Can be retaken as often as you wish

Mid-term Exams In the Testing Center Note the closing time is 4 pm! Problems similar to mastery checks and quizzes. All multiple choice. There are no late days.

Mid-term Exams Basic Section (30% of points) - Take only if you do not pass the Basic Test first - Consists of selected Basic Questions in multiple choice format - 10 problems Standard Section (70% of points) - Harder problems! - 23 problems

Final Exam In Testing Center Two parts: 1) One part like mid-terms; covers last material 2) One part comprehensive; short, multiple choice problems based on Basic Tests

Score Adjustments Purpose: I give credit for Homework and Classroom Exercises as an incentive for you to do them. Most students receive nearly full credit for them. But these scores are not very good for evaluation.

Score Adjustments Scores are calculated 4 different ways: 1.Regular method or … Lowest test weight is 10% less, other tests 5% more each and 2. Tests only scored Quizzes and Mastery Checks scored HW scored Labs and Clickers scored

Score Adjustments Percentile is the highest percentile of methods 2-5.

Tutorial Lab Primarily for homework help Tutors can help you with general questions as well N-304 ESC Open most hours through the day Look for Physics 220 tutors
