Magnetic Iron Powder / Iron Filings for Science Projects

Use this Iron Powder to demonstrate the powers of magnetism in your science projects. This Iron Powder is made of tiny particles of Iron. Each particle reacts to a magnet's presence making it very useful in demonstrating the direction of magnetic fields. 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.

Common projects involving Iron Powder:

• To demonstrate the reaction of the filings to magnets
• Study the effects of magnetism and electromagnetic fields
• Demonstrations: sprinkled on a white index card with a permanent magnet below
• Toys that allow one to draw with a magnetic pen
• Sprinkling over a card's magnetic strip to see the magnetic encoding of the strip
• Display the patterns of bits on a hard drive platter by pouring a semi-viscous fluid in which iron filings are suspended
