PHY132S - Introduction to Physics II
Electromagnetism Section
Spring 2009

Electricity and magnetism are at the heart of many devices that we use on a daily basis, including radios, televisions, computers, and electric appliances, as well as many electronic devices used in medicine. The electromagnetic force is also one of the fundamental forces of nature, binding atoms and molecules together to form matter. In this section of the course, we will study some of the basic principles of electromagnetism, including some applications to the life sciences.

SYLLABUS

The table below lists the planned syllabus and textbook references for the Electromagnetism Section of PHY132S. This table may be revised as the course proceeds. After each 11AM/5PM pair of lectures (i.e., on Monday and Wednesday evenings), the corresponding link in the More column will be activated, taking you to a page with all relevant materials that were presented in class.

The textbook is Physics for Scientists and Engineers: A Strategic Approach, Second Edition by Randall D. Knight, copyright 2008 by Addison-Wesley. We will be covering a selection of material from Chapters 26, 27, 29, 30, 31, 32, and 33, with the specific sections as listed below and given in the lectures. The corresponding sections from the First Edition of the textbook are also provided below.

Textbook chapters and sections that are listed below are examinable; those that are not listed or are explicitly omitted below are not examinable unless otherwise announced. All material covered in the lectures, whether in the textbook or not, is examinable.
