Filter cartridge magnetic attachment

A filter cartridge magnetic attachment comprising:

• a magnetic attraction means couplable to an exterior of a filter cartridge for magnetically attracting and retaining metallic particles within said filter cartridge, said magnetic attraction means comprising a heat sink having a first aperture extending therethrough spaced from a second aperture extending therethrough, said heat sink including a substantially planar base plate having a plurality of heat fins projecting substantially orthogonally therefrom, with said heat fins being separated by a transverse slot extending thereacross permitting a passage of said strap means over said base plate;
• a first magnet positioned within said first aperture of said heat sink, said first magnet having a first end and a second end;
• a second magnet positioned within said second aperture of said heat sink, said second magnet having a first end and a second end, and a shunt coupled to said first ends of said magnets for coupling magnetic flux directed from said first ends of said magnets together, thereby increasing magnetic flux directed from said second ends of said magnets, said magnets being substantially cylindrical in shape and having a diameter of a first distance with said magnets being spaced apart said first distance, said base plate of said heat sink further including an exterior perimeter edge from which said magnets are spaced, said magnets being spaced a second distance from said exterior perimeter edge, with said second distance being approximately equal to one half of said first distance, wherein said shunt comprises an elongated bar member having a height equal to said first distance, said bar member having a first recess directed thereinto receiving said first end of said first magnet, and a second recess directed into said bar member receiving said first end of said second magnet;
• and,
• a strap means for securing said magnetic attraction means to said filter cartridge, said strap means comprising an elongated flexible strap having a plurality of serrations extending therealong;
• a releasable lock secured to a first end of said flexible strap for receiving a second end of said strap therewithin to engage said serrations and lock said second end of said strap means proximal to said first end thereof.
