Visualization, simulation, and computing: New tools for learning, new paradigm for teaching

In this article we explore the role computing can play in an electromagnetics class. Our aim is not to provide answers, but to open a discussion on several topics related to the use of the computer as a learning aid. We provide some examples of what we have done in an introductory electricity and magnetism class using a program called SilverHammer that maps electric and magnetic fields for point charges. However, the point of this article is not to say that this is the only way computers should be used, but rather to point out that we really have only scratched the surface of a very versatile tool. Those who are presently working in this area are the pioneers, and will see the use of the computer go from these first applications to being an indispensable medium for learning. The computer may well let us create virtual scenarios that allow us to explore ideas and relationships with a heretofore unattained proficiency.
