Electromagnetic braking: a simple quantitative model
arXiv:physics/0603270 · doi:10.1119/1.2203645
Abstract
A calculation is presented which quantitatively accounts for the terminal velocity of a cylindrical magnet falling through a long copper or aluminum pipe. The experiment and the theory are a dramatic illustration of the Faraday's and Lenz's laws and are bound to capture student's attention in any electricity and magnetism course.
