Electromagnetism at Work

Speaker: Professor James A Rabchuk
Date: January 28, 2010 (Thursday)
Time: 4 p.m.
Room: 205 Currens Hall

Abstract:
The physical world is said to be controlled by four fundamental forces: gravity, electromagnetism, the strong and the weak nuclear forces. Of these forces, it can be said that electromagnetism is the strongest and best understood. It is the force that holds most material objects together, drives most chemical reactions, propels the flow of information along the internet at nearly light speeds, and is responsible for light itself, to name just a few things. This well-known force, however, continues to provide surprising new applications and present some significant mysteries. In this talk, I would like to address some of the ways in which the phenomenon of electromagnetism is being used in exciting, new applications, such as torque-sensing and ion trapping for use in quantum information processing. I will also speak about one of the more mysterious phenomena in electromagnetic theory, namely, electromagnetic induction. I will outline a non-traditional approach to understanding and teaching induction, as well as a proposed experiment that could test whether this approach is valid.

About the speaker:
Professor James Rabchuk is a professor of physics and the pre-engineering program coordinator at Western Illinois University. His research interests include the study of hydrodynamic stability, analytical and computational study of magnetoelastic materials, and simulations of electric and magnetic fields for ion trapping with applications for quantum computing.
