The Magnetic Pad is fitted with 6 rare earth magnets. These magnets omit between 1 700 and 2 200 gauss which is effective in creating a magnetic field within the affected area without creating heat. The pads fit in the same pockets as the hot and cold gel packs. Magnetic Therapy can be applied for up to a few hours depending on the injury. The rare earth magnets create a field which penetrates deep into the body tissues, muscles, nerves, tendons and bones. By increasing blood flow, the removal of toxins and organic waste matter from the injured area is greatly increased.
