A diameter of 30 mm is already an absurd size for a sphere magnet – so what can we write about this huge sphere with a 40 mm diameter?
Let's give it a try: A single magnetic sphere has a mind-boggling adhesive force of 23 kg! It is practically impossible to separate two of these magnets by hand once they are stuck together, you would need the help of a table edge.
Such a large sphere magnet is not really useful, unless you can think of something besides "bragging rights"? In that case, we look forward to hearing from you.
Thanks to a slightly thicker coating, chrome-plated magnets are better protected against abrasion than nickel-plated magnets. But, as with all large sphere magnets, the surface coating will not last forever, since the point-shaped contact areas are subjected to enormous forces. These magnetic spheres will be delivered individually packaged in a clear plastic tube.
