RIng Magnets with Iron Fillings

Iron fillings showing the magnetic field of two ring magnets. The magnetic field induces magnetism in each of the filings, which then line up in the field. Although the field is actually continuous, interactions between the filings cause them to accumulate in thin arcing lines.This image is part of a seris.
