A permanent magnet assembly for use in a therapeutic product comprising four disk magnets held in an edge-to-edge array with a steel washer as an armature under the four magnets. The holder for the magnetic parts comprises two integrally joined sheets of flexible plastic such as PVC, one sheet constituting a body having indentations forming cavities sized and shaped for the magnetic parts, and the other sheet constituting a cover folded over and sealed to the body sheet around the indentations to hold the magnetic parts in place. Four alternative embodiments comprise single-magnet arrays with flat magnets of different shapes held in holders similar to the holder of the first embodiment but with cavities that are the same shapes as the single-magnet arrays.

[ I claim as my invention:] [1.]1. In a magnet assembly including an array of disk-shaped permanent magnets having flat sides and narrow edges and arranged in edge-to-edge relation, and an armature disposed against said array in contact with corresponding flat sides of said magnets, a sealed, flexible magnet holder, comprising:a first sheet of flexible plastic having a first indentation defining a plurality of side-by-side first cavities in one side of the sheet, said cavities being of substantially the same size and shape as said magnets and receiving and holding the magnets in the edge-to-edge array;said first sheet having a further indentation in said first indentation defining a second cavity underlying said first cavities, said second cavity being of substantially the same size and shape as the armature and holding the latter under and against the magnets;a second sheet of flexible plastic overlying said first sheet and covering said cavities, said sheets being opposite end portions of a single elongated sheet and joined together by an integral fold;and means sealing said first and second sheets together around said first indentation thereby to hold the magnet array in sealed, assembled relation.
