Abstract: A drain plug comprising of a plurality of polarity magnets arranged in an alternating fashion. The plurality of polarity magnets are arranged in line with the drain plug. A magnet cover envelops the plurality of polarity magnets for easy cleaning. The unique alternating arrangements of the plurality of polarity magnets help increase the magnetic gradient for stronger attraction forces for metal wear particles. The use of a plurality of polarity magnets also increase the surface area where the metal particles can be held.

Abstract: A permanent magnet array iron filter has a generally circular collar made of a high magnetic permeability material with a plurality of magnetic assemblies interiorly disposed longitudinally around an interior circumference therein. Each magnetic assembly has two magnets with opposite poles facing the center of the filter and a gap between the adjacent assemblies. This arrangement intensifies the resultant magnetic field and projects the field deeply within the interior region of the filter. Rare earth permanent magnets are used to maximize the magnetic field. The collar may be coated with a plastic coating to protect the filter. The collar has a gap to provide flexibility when sliding the filter over an oil filter. The thickness of the collar may be adjusted to meet the requirements of a particular application.

Abstract: A magnetic array having a collar with a plurality of magnets mounted to the inner surface of the collar. The magnets are positioned in a spaced alignment around the collar with all having the same polarity facing toward the center of the collar. Shielding is used to control and/or contain the direction of the magnetic force and the array is covered with a plastic coating.

Abstract: An oil filter using a rare earth magnet positioned at the bottom or rim of the filter to capture excess metal particles unfiltered by the filter, the oil filter having a cylindrical body, a top adapted to receive oil, a bottom, the rare earth magnet having an extremely strong magnetic force is matingly attached to the bottom or top rim of the oil filter, or the rare earth magnet may be manufactured as part of the body of the filter.
