Motion in Electromagnetic Fields

Sometimes students have difficulty making the leap from abstract physics concepts to applications of basic principles in the real world. Motion in Electromagnetic Fields bridges the gap to understanding by focusing on practical examples and common scientific devices. This interactive tutorial explores the motion of charged particles in electric and magnetic fields at a level accessible to introductory students, yet it is thorough enough for professionals who want to develop a solid comprehension of these principles. Scenarios extend to a variety of fields, including chemical analysis, accelerator physics, high energy physics, and storage rings.

Part of a continuing series of software developed and produced by Whistlesoft, Inc. Motion in Electromagnetic Fields consists of five sections: circular motion in a uniform field, magnetic rigidity and spectrometer, Wien filter, cyclotron, and magnetron. A short tutorial steps through and [provides] exercises on cyclotron frequency. After the basic program operations become familiar, users can progress at their own pace throughout the various sections in either a linear or random fashion.

The hypertext interface for Motion in Electromagnetic Fields is fresh and easy to use. The contents screen links you to each of the five sections, and a concept map provides a more detailed overview of the program's topics using a hierarchical format by showing how principles are interrelated. An index links users to fast, simple explanations of topics and concepts that they will encounter throughout the tutorial. A question-and-answer section offers multiple-choice exercises with direct response feedback to enhance the learning experience, while a report card and bookmark option helps users keep track of progress through the various sections. Instructors will appreciate the on-screen laboratories, which give students the opportunity to explore in a structured environment.
