Iron Filings, 40 mesh, 500g For Sale

Examine the pattern of the magnetic field surrounding a magnet using these filings. These 40 mesh iron filings are devoid of grease. When pouring, uniform particle size enables a smooth, equal flow.

very useful for demonstrations
Iron particles will align themselves along the lines of the magnetic field when sprinkled over a piece of paper put close to a magnet, allowing you to see the shape of the field. This method can be used to examine the direction and strength of the magnetic field at different points surrounding the magnet.

Iron filings can be used to visualize magnetic fields as well as other magnetism-related concepts, such as the attraction and repellency of magnets and the impact of a magnetic field on moving charges.

to show what a magnetic field does to moving charges. Sprinkle iron filings on a piece of paper, then suspend a magnet over it. This will demonstrate how charged particles like electrons will have their paths deflected by the magnet.
