Physics II: Electricity and Magnetism

Course Description

This freshman-level course is the second semester of introductory physics. The focus is on electricity and magnetism, including electric fields, magnetic fields, electromagnetic forces, conductors and dielectrics, electromagnetic waves, and the nature of light.

Course Format

This course has been designed for independent study. It includes all of the materials you will need to understand the concepts covered in this subject. The materials in this course include:

  • A complete set of Lecture Videos by renowned MIT Physics Professor Walter Lewin
  • A complete set of detailed Course Notes, replacing the need for a traditional course textbook
  • A complete set of Class Slides, with overviews and illustrations of the concepts and applications of the subject
  • Homework Problems and Concept Questions to gauge your understanding of and progress through the materials
  • Homework Help Videos in which Prof. Lewin takes viewers step-by-step through solving homework problems
  • Visualizations of electromagnetic phenomena which are normally invisible to the human eye
  • An online study group at OpenStudy where you can connect with other independent learners

The content has been organized for linear progression through each of the Course Modules, starting with Electric Fields and concluding with The Nature of Light. It is a self-study course that you can work through at your own pace.
