Description: When a magnet is brought near a spinning disk it causes magnetic flux changes and the formation of eddy currents, which consist of moving charges and hence are themselves magnetic fields. Repulsive forces between the 2 magnetic fields cause the spin of the disk to slow. From TLP: Recycling of metals, http://www.msm.cam.ac.uk/doitpoms/tlplib/recycling-metals/eddy_current.php
