METHOD OF MAGNET LIQUID STABILISATION Russian patent published in 2008 - IPC H01F1/44 B03C1/32 

FIELD: electricity.

SUBSTANCE: invention is related to technology of magnet liquids preparation with stable properties, when they are exposed to uneven magnetic field, which are used in sealing devices, defectoscopy, in control instruments, in separation of non-magnet materials according to density, etc. Magnet liquid is exposed to gradient magnet field and is kept in the area of its influence until balanced concentration of magnet liquid disperse phase is achieved in every point of influence zone, after that part of magnet liquid that is found in the area with maximum induction of magnet field is separated, and remaining part of magnet liquid, which is found outside the area with maximum magnet induction is taken out from influence area of gradient magnet field.

EFFECT: preparation of magnet liquid that is stable in gradient magnet field.
