DEVICE FOR LEVITATION OF CERTAIN AMOUNT OF MATERIAL Russian patent published in 2014 - IPC H05B6/32 B60L13/04 

FIELD: electricity.

SUBSTANCE: invention refers to electrical engineering. Device includes coils maintaining material levitation using alternate electric current in coils. Two coils, first and second one, generate variable electromagnetic field. Tube out of non-conductive material is positioned between the coils and some amount of material used and levitated between the first and the second coils as they move along central coil axis inside the tube. First coil is positioned above second coil and has more windings. Coils are connected via one current source, or each coil has a separate current source. The tube is positioned vertically, with top hole open and bottom hole closed, and is filled with magnetic fluid. First coil with smaller number of windings is positioned at input hole. Levitating material suspended between electromagnetic fields of the first and second coils moves from open input hole to closed output hole of the tube under effect of magnetic fluid pressure force.

EFFECT: levitation of both conducting and non-conducting materials, simplified maintenance of standard heat and mass exchange process by both heating of levitated material and material cooling by immersion of a part of material into magnetic fluid affected by alternate electromagnetic current of first and second coils.
