Eddy Current Tube Demo

This classic physics demonstration shows how a magnet falling through a copper pipe will slow down as it transfers some of its energy to move electrons in the conductive copper pipe. Those moving electrons create a magnetic field which interacts with the magnetic field of the magnet to slow it down. This document describes how…
