Abstract
Students frequently experience difficulty visualizing complex multidimensional electrodynamics topics, especially those with time variation. The classic stationary illustrations of inherently dynamic concepts can be greatly enhanced via computer animation. Animation significantly improves student comprehension of time dependent functions, and provides a secondary benefit for students by improving computer programming skills.
Introduction
Computer animation is being used in a junior level electrodynamics class at the United States Naval Academy (USNA), one of the more abstract courses in the undergraduate electrical engineering curriculum. Animation of computer generated graphics provides a powerful learning tool to help students visualize abstract concepts, which is especially useful in electrodynamics since key electromagnetic concepts involve time dependent multidimensional problems.1 As an additional benefit, modeling this type of problem helps students improve their computer skills. The extensive student use of computers and industry standard software as engineering tools is a USNA electrical engineering department goal.
MATLAB, a popular technical programming tool with inherent graphical analysis features, is used throughout the electrical engineering curriculum at the USNA to (1) develop student proficiency in programming, (2) enhance the students’ numerical modeling expertise, and (3) improve the students’ comprehension of core subject matter. For the introductory electrodynamics class, a key to achieving a more rapid and complete student grasp of the technical concepts is MATLAB’s "handle graphics" feature.2 The "handle graphics" feature can simulate the evolution of multidimensional graphs over time. As a result, students are able to look at a rapid series of snapshots of a time dependent function as it develops, similar to the changing frames of a movie film.
