#### Course Description

Topics include concepts in electromagnetism together with their relationship to practical applications. Prerequisites: PHY 211 and its prerequisite requirements. Audit available.#### Addendum to Course Description

This is a calculus-based physics course required for students majoring in engineering, physics and chemistry. The course is transferable to other baccalaureate engineering programs. Students should be aware of the program requirements of the institutions to which they wish to transfer. This course conforms with the Oregon Block Transfer program.

#### Intended Outcomes for the course

After completion of this course, students will

1) Apply knowledge of electricity and magnetism to explain natural physical processes and related technological advances.

2) Use an understanding of calculus along with physical principles to effectively solve problems encountered in everyday life, further study in science, and in the professional world.

3) Design experiments and acquire data in order to explore physical principles, effectively communicate results, and critically evaluate related scientific studies.

4) Assess the contributions of physics to our evolving understanding of global change and sustainability while placing the development of physics in its historical and cultural context.

#### Course Activities and Design

Principles and techniques are presented through lectures and class demonstrations. Students must register for lecture, one recitation, and one lab. Laboratory work will be performed in order to clarify certain facts in the lecture materials.

#### Outcome Assessment Strategies

At the beginning of the course, the instructor will detail the methods used to evaluate student progress and the criteria for assigning a course grade. The methods may include one or more of the following tools: examinations, quizzes, homework assignments, laboratory reports, research papers, small group problem solving of questions arising from application of course concepts and concerns to actual experience, oral presentations, or maintenance of a personal lab manual.

Specific evaluation procedures will be given in class. In general, grading will be based on accumulated points from homework assignments, tests, final exam, and labs.

#### Course Content (Themes, Concepts, Issues and Skills)

**COURSE CONTENT:**

1.0 CHARGE AND MATTER

Goal: The goal is to gain knowledge and develop skills in the basic concept

of electric forces.

Objectives:

1.1 To learn the concepts of charge and current.

1.2 To learn and understand how to use Coulomb's law, the

force law which gives the electrostatic force between point

charges.

2.0 THE ELECTRIC FIELD

Goal: The goal is to gain knowledge and develop skills in the concept

of electric fields.

Objectives:

2.1 To learn the definition of the electric field, E.

2.2 To learn the formula for the electric field due to a

single point charge. The student should be able to quickly

derive this using Coulomb's law and the definition E.

2.3 To learn to calculate E due to any given distribution of

charge. This involves dividing the distribution of charge

into point charges and then applying the equation to each such

point charge.

3.0 GAUSS'S LAW

Goal: The goal is to gain an understanding of Gauss° law, and to use it

to calculate electric fields due to various charge distributions.

Objectives:

3.1 To understand the definitions: (a) vectorial surface area

element; (b) flux of a vector field (the flux of fields other

than E will be involved); (c) open and closed surfaces.

3.2 To learn the formula for Gauss's law and very clearly

understand the meaning of the symbols in it.

3.3 To learn how to apply Gauss's law to problems. This is

probably more difficult than "applying" most of the previous

physical laws to problems. The student will find that the

problems are usually one of the following two types.

a. Calculate E due to a given distribution of charge.

The charge distribution must have sufficient symmetry.

b. Calculate something about the distribution of charge

on a conductor. Use is made of the fact that E = O

within a conductor in electrostatic equilibrium.

4.0 ELECTRIC POTENTIAL

meant by electric potential.

Objectives:

4.1 To learn the definition of potential difference and its

relation to the potential energy difference.

4.2 To learn the formula for the potential due to a single

point charge.

4.3 To learn how to apply the above formula in order to

calculate V due to any distribution of charge.

4.4 To learn the relation between power, current, and

potential difference. This will be used in later applications

to electric circuits.

5.0 CAPACITORS AND DIELECTRICS

Goal: The goal is to gain knowledge of how a capacitor works, and to

understand how capacitance is affected by the presence of a dielectric.

Objectives:

5.1 To learn and understand the definition of the capacitance
