Product information
Important note: These sphere magnets / magnetic spheres are not suitable as toys for children.
The possible choking hazard for children under 36 months is just one risk.
Since the magnetic spheres in the intestine attract each other, they no longer leave the body naturally and can pinch the sensitive tissue and thus lead to serious injuries.

  • The product conforms to the European RoHS Community legislation

  • 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!
  • Determination of the magnetic force

    The adhesive force of our magnets is determined at room temperature on a polished plate made of steel S235JR (ST37) with a thickness of 10 mm by the vertical withdrawal of the magnet (1kg ~ 10 N). A different value down to -10% compared to the specified value is possible in exceptional cases. In general, the value is exceeded. Please note that for thinner, painted and not absolute plan undergrounds the adhesive force represents only one raction of the specified values.

Bin mit den Neodym Magneten sehr zufrieden. Die kleinen Neodym Magnete haben eine ausgezeichnete Haftkraft. Nicht gerade billig aber das Preisleistungsverhältnis ist OK.
