Abstract
A reusable magnetic device for the extraction of ferrous particles from a body of fluid, wherein the device comprises a plurality of magnets and soft ferrous metal spacers arranged in an alternating sequence to form a stack, the spacers each having a first axial length that is between 12% and 13% greater than a second axial length of each of the magnets, adjacent magnets being arranged with like poles facing, a non-magnetic and non-ferrous end piece terminally disposed at a first end of the stack, and a non-magnetic housing that contains the magnets, the spacers and the end piece. The magnetic device can be installed in a vessel to provide a fluid filtering assembly.

A reusable magnetic device for the extraction of ferrous particles from a body of fluid, wherein the device comprises:
- a plurality of magnets and soft ferrous metal spacers arranged in an alternating sequence to form a stack, the spacers each having a first axial length that is between 12% and 13% greater than a second axial length of each of the magnets,
- adjacent magnets being arranged with like poles facing,
- a non-magnetic and non-ferrous end piece terminally disposed at a first end of the stack, and
- a non-magnetic housing that contains the magnets, the spacers and the end piece, the end piece being selected such that a magnetic field is not present at a terminal tip of the housing adjacent the end piece.
A magnetic filter assembly for the extraction of ferrous particles from a body of fluid, comprising:
- a magnetic rod including a plurality of magnets and soft ferrous metal spacers arranged in an alternating sequence to form a stack, adjacent magnets being arranged with like poles facing, the spacers each having a first axial length that is between 12% and 13% greater than a second axial length of each of the magnets,
- a non-magnetic and non-ferrous end piece terminally disposed at a first end of the stack, and
- a non-magnetic housing that contains the magnets, the spacers and the end piece, the end piece being selected such that a magnetic field is not present at a terminal tip of the housing adjacent the end piece;
- and
- a cylindrical vessel within which the magnetic rod is removably mounted, the vessel having fluid inlet adjacent its first end and a fluid outlet adjacent its second end.
