SECTION : Faraday's Law       

  
SUBJECT: The Suspended Ring  
 
DESCRIPTION:

The animation shows the magnetic field configuration around a conducting non-magnetic ring (e.g. copper) as it falls under gravity in the magnetic field of a fixed permanent magnet. The current in the ring is indicated by the small moving spheres. In this case, the ring is light and has zero resistance, and is suspended below the magnet. The motions of the field lines are in the direction of the local Poynting flux vector.
