Product information
Now it's getting serious:
This large magnetic sphere with a diameter of 40 mm is not for magnetic laymen!
Our neodymium sphere Ø 30 mm already has a considerable adhesive force of a good 12 kg. But this tops the value again by over 10 kg!
Due to the high adhesive force of 23 kg, two spherical magnets cannot simply be separated from each other. To do this, you would have to use a table edge or mechanical device. In contrast to the usual nickel coating, the surface here is chrome-plated. The advantage is the higher abrasion resistance of the coating.
To this day, we are not aware of any really useful use. But maybe you have a practical application at hand? As with all neodymium spherical magnets, the amazing adhesive force only works selectively. It can happen that the coating does not last forever on this contact surface.
This spherical magnet is far too strong for a memo board, and also too dangerous.
 
Each magnetic sphere is packed individually. That is also sorely needed with this adhesive force.

  • Safety Notice

    NdFeB magnets are hard and brittle. Especially with thinner dimensions / higher adhesive forces, these can easily break or splinter! An uncontrolled impact of two magnets as well as an external, mechanical shock or pressure load should therefore be avoided!
