A magnetic separation device has a membrane having a plurality of pores, a magnetically soft material layer disposed on the membrane, and a passivation layer disposed on the magnetically soft material layer. The magnetic separation device may be part of a microfluidic device having a lateral flow channel and a vertical flow magnetic separation filter. The magnetic separation device may be used to separate magnetically tagged particles, such as cells.

A tiered magnet modular collar designed to catch metallic objects inside a garbage disposal. The tiered magnet modular collar includes a plurality of tiered magnets, each tiered magnet having a first elongated member offset from a second elongated member. The first elongated member is atop a second elongated member via a connecting bar. The first elongated member has a first distal end opposite a first proximal end with a first interior surface opposite a first exterior surface. The second elongated member has a second distal end opposite a second proximal end with a second interior surface opposite a second exterior surface. The first elongated member and second elongated member have an arcuate shape such that the tiered magnets affix to one another in an annular manner. In this way, a user is able to affix the tiered magnet modular collar around a garbage disposal to catch metallic objects inserted therein.

The present invention includes a method of controlling an oil spill through introduction of a plurality of magnetizable particles into the oil spill in an amount sufficient to form a colloidal mixture. An absorbent is, also introduced into the oil spill to form an absorbent mixture. A magnetic field can be applied to the system to move, manipulate, or otherwise control the absorbent mixture in response to movement of the magnetic field.

A system for sorting metallic objects by magnetic separation has an electromagnetic core. The electronic core includes at least a first portion, a second portion, and a bottom. A sorting flap is arranged facing the electromagnetic core to fashion a circulation space for a conveyor of objects to be sorted from the first portion toward the second portion. The sorting flap includes a magnetic element arranged to form an air gap (E1) between the first portion and the sorting flap. The air gap forms a magnetic barrier opposing the passage of non-magnetic metallic objects, such that the objects are ejected from the conveyor. The second portion is arranged to ensure a return of the magnetic flux lines toward the first portion.

The present invention is a portable air purifier device intended to be attached to the belt or to the neck of a user. Purified air is generated by electrochemically and magnetically treating a polluted air. Polluted air is forced through an ionized water, which absorbs particles and kills possible air born bacteria. A magnetic filter assures that small metal particles are also separated from the polluted air. The purified air is then delivered towards the face of the user either through an air curtain or through a mask.

A system for reducing dust emissions resulting from tire abrasion, comprising a collecting unit (1), arranged at a distance from the tread (4) of a tire (5) and has at least one first electromagnet and/or permanent magnet (2). At least the material with which the tread (4) of the tire (5) is formed is magnetic or is ferromagnetically, ferrimagnetically or anti-ferromagnetically magnetisable, so that the tire abrasion particles (6) created as a result of abrasion of the tread (4) are magnetic or are ferromagnetically, ferrimagnetically or anti-ferromagnetically magnetisable. The at least one first electromagnet and/or permanent magnet (2) is designed to magnetise tire abrasion particles (6) and to accumulate the magnetized tire abrasion particles (6) detached from the material of the tread (4) in a collection point (3), arranged on a vehicle.
