K-19-C Sphere magnet Ø 19 mm

NdFeB, N38, chrome-plated

Real monster-spheres! I know adults who were not able to separate these magnets from each other. These should be handled with care and are definitely not suitable for children! (No joke!)

Keep in mind: These spheres are coated with chrome (over a nickel base), which makes them especially robust. Nevertheless, you should not let two of these spheres collide together - the pressure on the points of impact will be so high that the coating may be broken-down over time. Orders of multiple spheres will be delivered with a plastic spacer between them.
When you order 5 spheres, you'll receive the K-19-C packaged with spacers in such a plastic tube.
Even the 45 mm thick "TCP/IP-Illustrated" is no real hindrance for these giant magnetic spheres.
Note: only the large sphere (K-19-C) on top is magnetic. The other 8 are simple, non-magnetic, steel spheres that are magnetised through the one magnetic sphere.
2 sphere magnets K-19-C attract each other without a problem through my forearm. Admittedly, I am only an average office-based guy and don't have construction worker arms, but still....
Somewhere in the midst of these steel spheres, there is one K-19-C.
Through a hand without a problem.
