Abstract:
|
When President Garfield was shot on July 2, 1881, physicians could not determine the location of the bullet. Alexander Graham Bell proposed that he use his newly invented telephone and another relatively new development, the induction balance, to locate it [1]. This early attempt at nonintrusive medical imaging ultimately failed. The apparatus provides students with a way to learn several aspects of electromagnetism and AC circuits in a context that should be motivating to medical students who are studying physics. Even the reasons for the failure are directly related to understanding magnetic fields. Our progress toward developing a teaching activity on this topic has included creating an induction balance with readily available materials and detecting the location of hidden pieces of metal. This project is funded by NSF under grant DUE 04-26754.
