Abstract
We present an analytical study of magnetic damping. In particular, we investigate the dynamics of a cylindrical neodymium magnet as it moves through a conducting tube. Owing to the very high degree of uniformity of the magnetization for neodymium magnets, we are able to provide completely analytical results for the EMF generated in the pipe, and the consequent retarding force. Our analytical expressions are shown to have excellent agreement with experimental observations.
