Predicting the Influence of Plate Geometry on the Eddy Current Pendulum
arXiv:1506.06401 · doi:10.1119/1.4954016
Abstract
We quantitatively analyze a familiar classroom demonstration, Van Waltenhofen's eddy current pendulum, to predict the damping effect for a variety of plate geometries from first principles. Results from conformal mapping, finite element simulations and a simplified model suitable for introductory classes are compared with experiments.
