This web site can be used to access self-tests and build conceptual inventories on topics in electricity and magnetism. The topics covered range from charges and electrostatics to circuits, magnetic fields, and electro-magnetic waves.

In self-test mode, a learner can access concept quizzes consisting of 5 multiple choice questions covering a selected topic. Questions are pulled from an extensive question database. These quizzes are graded, solutions provided, and a cumulative score kept for each session.

In Concept Inventory mode, an instructor or learner can build concept quizzes from the question database. In building these quizzes, the number of questions, topics covered, and specific questions can all be selected. The resultant quizzes can be printed, solutions created, or downloaded for import into the Blackboard Course Management System.
