A method of creating a zone of high-gradient magnetic field in a Kittel open domain structure is disclosed. The method is based on a magnetic system of an open domain structure type and is embodied in the form of two substantially rectangular constant magnets which are mated by the side faces thereof, whose magnetic field polarities are oppositely directed and the magnetic anisotropy is greater than the magnetic induction of the materials thereof. The magnets are mounted on a common base comprising a plate which is made of a non-retentive material and mates with the lower faces of the magnets, thin plates which are made of a non-retentive material, are placed on the top faces of the magnets and forms a gap arranged above the top edges of the magnets mated faces. A nonmagnetic substrate for separated material is located above the gap.

Method for forming a high-gradient magnetic field and a substance separation device based thereon

The invention relates to a magnetic separation device and is used for separating paramagnetic substances from diamagnetic substances, the paramagnetic substances according to the paramagnetic susceptibility thereof and the diamagnetic substances according to the diamagnetic susceptibility thereof. Said invention can be used for electronics, metallurgy and chemistry, for separating biological objects and for removing heavy metals and organic impurities from water, etc. The inventive device is based on a magnetic system of an open domain structure type and is embodied in the form of two substantially rectangular constant magnets () which are mated by the side faces thereof, whose magnetic field polarities are oppositely directed and the magnetic anisotropy is greater than the magnetic induction of the materials thereof. Said magnets () are mounted on a common base () comprising a plate which is made of a non-retentive material and mates with the lower faces of the magnets, thin plates () which are made of a non-retentive material, are placed on the top faces of the magnets and forms a gap arranged above the top edges () of the magnets () mated faces. A nonmagnetic substrate () for separated material () is located above the gap ().
