For this interesting and cool experiment you will need:
00:00 - Neodymium magnets: the strongest in the world - supermagnete. Neodymium is a rare earth metal and a special material: Combined with iron and boron it creates the currently strongest permanent magnets in the world. They can be produced in various shapes (discs, blocks, cubes, rings, rods and spheres). Their nickel-copper-nickel coating lends them an appealing silver surface. Hence, these special magnets are great as gifts for arts and crafts fans and model makers.
00:06 - Iron filings are very small pieces of iron that look like a light powder. They are very often used in science demonstrations to show the direction of a magnetic field. Since iron is a ferromagnetic material, a magnetic field induces each particle to become a tiny bar magnet. The south pole of each particle then attracts the north poles of its neighbors, and this process repeated over a wide area creates chains of filings parallel to the direction of the magnetic field. Iron Filings are used in many places including schools where they test the reaction of the filings to magnets.
