A magnet holder accessory for releasable solely magnetic mounting to a metal oil filter cartridge has a magnet housing wherein the magnet housing consists essentially of an upper surface member an opposite lower surface member and side surface members extending around so as to enclose a magnet retaining cavity within the magnet housing, the side surface members contiguous to the perimeter of the lower surface member and the upper surface member, the magnet retaining cavity sized to snugly retain a magnet within the cavity a first distance from a lower surface of the lower surface member and a second distance from an upper surface of the upper surface member, wherein the first distance is a relatively small distance for minimizing attenuation of magnetic force of a magnet within the magnet retaining cavity, and the second distance is a distance significantly larger than the first distance so as to attenuate the magnetic force from the magnet retained within the magnet retaining cavity. The lower surface member us a generally planar thin resilient membrane mounted around its circumference to the side surface members and covering the magnet when within the cavity whereby the magnet holder is adapted to be releasably solely magnetically mounted to an exterior surface of the metal oil cartridge when the magnet is retained within the magnet retaining cavity.

[ What is claimed is:] [1.] A magnet holder accessory for releasable solely magnetic mounting to a metal oil filter cartridge comprising:a magnet housing,wherein said magnet housing consists essentially of an upper surface member, an opposite lower surface member, and side surface members extending around, so as to enclose, a magnet retaining cavity within said magnet housing, said side surface members contiguous to the perimeter of said lower surface member and said upper surface member,said magnet retaining cavity sized to snugly retain a magnet within said cavity a first distance from a lower surface of said lower surface member, and a second distance from an upper surface of said upper surface member, wherein said first distance is a small distance and said second distance is a distance significantly larger than said first distance,wherein said lower surface member is a generally planar thin resilient thin membrane mounted around its circumference to said side surface members and covering said magnet when within said cavity whereby said magnet holder is adapted to be releasably solely magnetically mounted to an exterior surface of said metal oil filter cartridge when a magnet is retained within said magnet retaining cavity,and wherein said magnet housing is not a means for assisting mounting said magnet to said oil filter cartridge other than by retention of said magnet held within said magnet cavity.
