# Quizbank/Electricity and Magnetism (calculus based)

These quizzes closely follow examples in OpenStax University Physics Vol. 2 Unit 2.
Maybe that will get their noses into the book!

• Quizbank now resides on MyOpenMath at https://www.myopenmath.com (although I hope Wikiversity can play an important role in helping students and teachers use these questions!)
• At the moment, most of the physics questions have already been transferred. To see them, join myopenmath.com as a student, and "enroll" in one or both of the following courses:
• Quizbank physics 1 (id 60675)
• Quizbank physics 2 (id 61712)
• Quizbank astronomy (id 63705)

The enrollment key for each course is 123. They are all is set to practice mode, giving students unlimited attempts at each question. Instructors can also print out copies of the quiz for classroom use. If you have any problems leave a message at user talk:Guy vandegrift.

## Student study guide

Equation sheet for students to use while taking these quizzes. Available in three formats:
1. Online page
2. Online pdf
3. Wikiversity file

This unit has 12 classroom-read quizzes that can viewed by clicking the links (c05, c06,c06...) shown below. Each link offers the instructor a choice of 26 randomly selected quizzes. For each quiz versions V1 and V2 pose the same questions but in different order and with different numerical values. Students and instructors can also view all the questions on this unit's /Questions list. More suggestions for use by instructors can be found at Quizbank/Instructions.

The fractions shown below are an artifact of the software: Most such "exams" (/c05, /c06, ...) are random selections from more than one "quiz" (QB/d_cp2.5, QB/d_cp2.6...). For example, 2 exams based on these same quizzes can be found here.

c05: 4/6 from Special:Permalink/1894334 to QB/d_cp2.5
c06: 4/6 from Special:Permalink/1894335 to QB/d_cp2.6
c07: 4/11 from Special:Permalink/1893815 to QB/d_cp2.7
c08: 4/4 from Special:Permalink/1893633 to QB/d_cp2.8
c09: 4/10 from Special:Permalink/1893634 to QB/d_cp2.9
c10: 4/9 from Special:Permalink/1895273 to QB/d_cp2.10
c11: 4/9 from Special:Permalink/1902372 to QB/d_cp2.11
c12: 4/11 from Special:Permalink/1892310 to QB/d_cp2.12
c13: 4/9 from Special:Permalink/1893631 to QB/d_cp2.13
c15: 4/8 from Special:Permalink/1894891 to QB/d_cp2.15
c16: 4/6 from Special:Permalink/1895295 to QB/d_cp2.16

In most cases is should be possible to learn how to do these problems by reading the examples in the textbook

## Equations for students to use as they take these quizzes

The following link to two sets of equations for each chapter. The second (smaller) one is intended for students to use as they take the tests.

## How this works

QB/d_cp2.5 denotes Volume 2 Chapter 5 of University Physics. The fraction 4/5 informs the student that four out of the five questions will be randomly selected. I chose four per quiz to encourage instructors to try this out as unannounced "pop" quizzes (before, during, or after the lecture.) It is usually possible to display four questions on an overhead projector.[1]

All 4-question quizzes come in two student versions (V1,V2). Each version has the same questions for each quiz, but with different number inputs and in different order. The instructor will have a pdf file that can be delivered in a number of ways. All delivery systems will be free of charge, and some require almost zero effort on my part. Instead of attempting to suppress students gaining access to the exam bank, they will be posted publicly.

## Quizzes are hidden in plain sight

Each quiz comes in many renditions, and each renditions come in three versions. Versions V1 and V2 are for classroom use and contain the same questions in random order with random numerical values.[2] Hiding these materials in plain sight greatly simplifies the distribution of this (free) "product". The commercial vendors will continuously evolve their materials in order to continue selling products.[3]

## A card game for Bell's theorem and its loopholes

People can't win some versions of this game unless they cheat or are lucky

Since the course also covers optics, polarization, and a bit of modern physics, I am thinking of introducing Bell's theorem. The following quizzes have been developed for this unit, but a few more need to be written:

I think Tube entanglement could be used to introduce quantum mechanics after OpenStax University Physics Volume 3 has been mastered. For more information on Bell's theorem at a level appropriate for this course see:

## Footnotes

1. If a projector is used and students are too close together, assign the even/odd questions to alternate seats. It is recommended that the grades be adjusted according to any difference in difficulties between (even/odd) selections. It is also possible to average out such unfairness by offering at least one in-class quiz for each chapter. Finally, such quizzes should not greatly contribute to the grade (I also give attendance credit for getting zero questions on a quiz.)
2. Version V0 is an instructors version in which the questions follow the books chronological order. This is not really necessary on these short quizzes, but on longer exams, V0 can help instructors design their lectures to match the exams.
