Magnetic Field Viewing Kit with Steel Filings from Dowling Magnets

A mess-free, transparent viewing tray made of scratch-resistant plastic seals steel filings inside, ensuring cloud-free viewing. Rubber-coated magnets (.75 inch disc magnet and 1 inch bar magnet) are included to prevent scratching, along with a filing-filled tray measuring 3.44 inches in diameter. The steel filings are cleaner than iron filings and provide a clear view of a magnet’s invisible force field. This tool allows users to manipulate the magnet with their own hands, providing an up-close look at the basics of magnetism, including attraction, repulsion, and polarity. The small bar magnet has color-coded poles (red for north and blue for south).

The scratch-resistant plastic viewing tray can withstand classroom use and allows for easy observation of the invisible lines of force produced by the magnets. By gently shaking the tray and tipping it to one side, users can see how certain areas of the magnet attract more filings, indicating the location of the magnet’s poles. Differences between the areas of attraction for the disc magnet and the bar magnet can be observed, as well as the breaks in the pattern of the filings inside the tray, which indicate the separations between the magnet's poles.

This resource is suitable for ages 8 and up, as well as grades 3 and above, and has been safety tested in the US. It provides a hands-on way to learn about the fundamentals of magnetism, offering a clear and visually engaging way to explore the topic.
