Abstract: A magnetic therapeutic device having one or more flexible strands (such as monofilament nylon line) detachably connectable at a first end with a first end magnetic clasp and a second end with a second end magnetic clasp while the strands hold magnetized hematite beads (which substantially surround the strands) and, optionally, decorative beads (which may be made of a natural stone), between the first and the second ends so that a closed loop with a continuous magnetic field (which can have a strength of at least approximately 50,000 gauss) is formed when the first and the second magnetic clasp are joined together. When multiple strands are included in a single device, multiple magnetic clasps and spacers (which may be magnetized hematite beads) hold the strands together. The therapeutic can be a necklace or a bracelet worn on a wrist or ankle by humans, or a neck collar or leg wrap worn by animals.
