Therapeutic magnetic device comprising magnetite Fe3 O4 featuring a magnetic circuit

摘要

A magnetic therapeutic device is provided, comprising a non-electrically conductive strand and a plurality of magnetic beads. Each bead has a hole through its center (“bead hole”) and has a North pole edge and a South pole edge forming a magnetic field parallel to the bead hole. The plurality of beads are in a linear touching arrangement in which the North pole edge of a first bead touches the South pole edge of a second bead, the North pole edge of the second bead touches the South pole edge of a third bead, and continuing until the North pole edge of a next-to-last bead touches the South pole edge of a last bead and the North pole edge of the last bead touches the South pole edge of first bead, thereby completing a magnetic circuit.
