Neodymium is a rare earth metal und 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.
Super-strong adhesive force
Suitable for small spaces (miniaturisation)
Even the smallest neodymium magnets are just a strong a larger common magnets
