Description

Please note: These are NOT magnets!

These steel spheres with a diameter of 12,7 mm are great for joining with magnets. And when combined with rod magnets, you can build some pretty crazy structures.
The steel balls are made of high carbon chromium steel that contains 1% carbon and 0,5 %–1,65 % chromium. The spheres are plated with nickel (Ni-Cu-Ni).

Additional features and tips

Not magnets... steel spheres.
From above.
Dramatic enough?
This structure rotated with a single push for 25 minutes! The explanation for this is the low amount of friction and the minimal amount of aerodynamic resistance. The low friction stems from the two steel spheres (on top) having contact over a very small surface area only and also because the structure is so heavy, that it is nearly ready to fall. By the way, the two steel spheres are not magnets, but are magnetised through the rod magnets.
