Production technology: Spherical magnets can be produced by pressing of high-refined powders (ferrites or NdFeB) following with sintering and grinding or by balling in specially designed granulator.

Application: As singly units spherical magnets (SM) can be used as a source of high gradient fields (compass, controlling component of hermetically sealed and Hall effect based devices and sensors). In conglameration, SM (magnet balls) work as a special magnetic system of interacting magnetic spheres.

Conglamerated SM can be used as efficient magnetic filters and, in particular, for magnetic treatment of various biological objects and liquids.

Features :

• SM can be packed in filters with high density (up to 70% of working space of a filter).
• SM can be magnetized after assembling filters.
• SM allow an opportunity to get layers of assigned directions of magnetic fields; at alternation of SM layers of opposite directions of magnetic fields the most favorable condition takes place for magnetization of filtered liquid.
• SM have a higher gradient of magnetic field than magnets of other shapes.
