Section:
This course is a one semester introduction to electricity and magnetism. It is the second course in a four semester introductory sequence that includes Physics 105 and Physics 201-202 or 319-320. As such, it is primarily intended for students who are planning to take at least two years of physics courses. Students planning to take a single year of physics should consider the introductory 101-102 or 103-104 sequences.
The goal of this course is to give a solid grounding in the core topics of
classical electricity and magnetism, and to prepare students for further study
in physics. It will not contain a survey of "Modern Physics" such
as found in Physics 102 or 104. Calculus will be used in keeping with the
students'; level of math preparation, and additional mathematical
techniques will be introduced as needed.
Required: E. M. Purcell, Electricity and Magnetism,
2nd Edition (McGraw Hill, New York).
Recommended: Used Math by Clifford Swartz
The book by Purcell is a classic book that treats the material with more mathematical sophistication than most introductory texts. Supplementary material will be used for a treatment of ray optics and in place of sections that rely on special relativity. The book by Swartz, which veterans of 105 may already have, is a useful primer/reminder for the math used in the course.

Solving problems is not only the best way to learn physics, it is the only way. For this reason, the problem sets are probably the most important part of the course. You may work together on the problem sets; however the final write-up must be your own. To get the greatest benefit from the problems sets you should attempt to think through every problem yourself before discussing it with others. Problem sets are due on the Wednesday the week after they were assigned. Homework will be graded and returned with solutions by section on Thursday. No credit will be given for homework submitted after the solutions are distributed.
Your homework should clearly indicate what steps you have taken in
reaching your answer and why. Simply stating the answer is not sufficient.
The strength of the university depends on academic and personal integrity.
In this course, you must be honest and truthful. Ethical violations include
cheating on exams, plagiarism, reuse of assignments, improper use of the
Internet and electronic devices, unauthorized collaboration, alteration of
graded assignments, forgery and falsification, lying, facilitating academic
dishonesty, and unfair competition. As
noted above, collaboration on homework sets is encouraged. However, you should attempt problems
independently before collaborating and must write up your homework independently.
Report any violations you witness to the instructor. You may consult
the associate dean of students and/or the chairman of the Ethics Board
beforehand. See the guide on "Academic Ethics for Undergraduates" and
the Ethics Board web site (http://ethics.jhu.edu
) or http://www.advising.jhu.edu/ethics.html
for more information.
Syllabus: The syllabus will be updated as the course
progresses.
