Iron Filing Bubble Magnetic Field Viewer

This iron filing viewer bubble is sealed to avoid messy handling of iron filings & is safe for use by small children. The magnet is not included but any kind will do. We recommend ferrite block magnets since they are quite strong but inexpensive & will cause the filings to stand straight up. If you opt for a bar magnet, you will be able to see the magnetic field lines form clearly.
