This amazing plastic tube with iron filings enables one to visualize magnetic fields around an included Alnico magnet. By moving the Alnico (Aluminum-Nickel-Cobalt) cow magnet inside the tube hole iron filings will string together to form visible 3D structures in the shapes of the magnetic field lines. This tube is a great learning tool in demonstrating magnetic fields, and their interaction with iron.
