"Experiment illustrating the molecular theory of magnetism. Coarse steel filings are placed inside a small glass tube and the contents magnetized. It will be found that filing which at first had no definite arrangement will rearrange themselves under the influence of magnetic force, and assume symmetrical position, each one lying in line with, or parallel to its neighbor, as shown in the lower figure." -Hawkins, 1917
