We have used magnetic therapy for years to promote pain relief and healing. We use both customized fixed magnetic strips and pulsing magnetic beds. We determine with applied kinesiology whether the animal wants the bio North or bio South side of the magnet. The bio South side is more like adding heat to an area and increasing circulation, whereas the bio North side is like applying an ice pack. The magnets that we use have over a two inch perceptible magnetic field which penetrates through living tissue, which is beyond what a heating pad or ice pack would do, because the blood is continually taking away the heat or cold from the area.
