CourseDescriptionandCourseObjectives
Electricity & Magnetism for students in science and engineering. This is the second semester of a two-semester
sequence in introductory physics. Topics include material covered in chapters 21-32 of the textbook, “University
Physics”(seeTextandRequiredMaterialsbelow).
Knowledgetogain:Understandingofmaterialcoveredinchapters21-32ofthetextbook,UniversityPhysics.
Skillstogain:Abilitytoworkthroughcomplexproblems.
SeeattachedlistofLearningObjectives.
Pre-Requisites:
PHYS218andMATH151or171.
Youmusthaveaworkingknowledgeofplanegeometry,trigonometry,andalgebra.Youwillalsobeexpectedtohave
aworkingknowledgeofderivativesandintegrals,andbeproficientintheuseofvectors(addition,subtraction,dot
andcrossproducts).
Co-Requisite:MATH152or172.

Pre-Lectures: PHYS 208 lectures follow a “flipped course” model, and as part of that we are using a pre-lecture
systemhostedontheonlineFlipItPhysicssite.PleaseenteryourUINforyour‘uniqueidentifier’whenregistering,to
ensurethatyougetcreditforyourwork.Youarerequiredtoviewthepre-lectures(narratedslidesincludingafew
online questions) ahead of the lectures, and the lectures will include quizzes to see if you have gained a basic
understanding. The remainder of the lecture can then focus more on problem-solving. The FlipItPhysics site also
includes “Checkpoints” following most pre-lectures, which are short quizzes to test for understanding. The course
codeforthiscourseis:4cf56102.
Lectures and Clickers: The iClickers will be used for in-class conceptual testing and polling. To encourage class
participation,creditforiClickerswillbebasedinpartonparticipation,aswellasadditionalpointsbasedoncorrect
answers. Full participation credit allows for 3 “free drops” (missed classes), to avoid complicated accounting for
excusedabsences.Togainparticipationcredityoumustpre-registeryourdevice,andanswerallofthequestionsin

Absences:
If you miss an exam due to an authorized excused absence as outlined in the University Regulations, you should
attempt to contact me prior to the exam, but no later than the next class meeting following the missed exam to
arrange for a makeup exam. With an official excuse, the missed exam score will likely be replaced by the makeup
examscore.Note:Fewconditionsqualifyasanauthorizedexcusedabsence,soyoumustavoidmissingexamsexcept
