Iron Filing

This illustration shows iron filings being attracted to a small neodymium magnet.

Iron Filing in 12 oz. Shaker Bottles
Iron Filing in 1 lb. Containers

12 ounces of iron filing packaged in a shaker for convenience plus screw cap for 
safe-keeping. They are ideal for experimentation with magnetic fields.  

When you place these filings on any magnet, you can visualize 3D magnetic 
fields. This demonstration is very common in the classroom and provides  
a great opportunity to further study the magnetic properties for yourself.

Iron Filings Experiment

Place a magnet under a piece of paper and shake the filings on top. 

The filings will reveal the magnetic field lines. To avoid
creating a mess, place the iron filings in a zip-lock bag.
