  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.
