Iron Filings in Plastic Tube-1 oz.

Iron filings are very small pieces of iron that look like a light powder.  They are very often used in science demonstrations to show the direction of a magnetic field.  Since iron is a ferromagnetic material, a magnetic field induces each particle to become a tiny bar magnet.  The south pole of each particle then attracts the north poles of its neighbors, and this process repeated over a wide area creates chains of filings parallel to the direction of the magnetic field.  Iron Filings are used in many places including schools where they test the reaction of the filings to magnets.  The primary use of iron filings is in the study and teaching of magnetism and electromagnetic fields.  The substance makes impressive demonstrations when sprinkled on a white card placed on top of a permanent magnet.  The filings are also found in toys that allow one to draw with a magnetic pen.  Additionally, by sprinkling fine iron on a magnetic stripe card, it is possible to see the magnetic encoding on the stripe.  Another demonstration is to pour onto the exposed platter of a hard drive a semi-viscous fluid in which iron filings are suspended, so that the patterns of bits on the platter are revealed by the alignment of the iron filings. 

Probably the newest fad with iron filings is making awesome designs in nail polish.  Click here for step-by-step instructions on how to mix it in your nail polish.
