The fact that iron, a magnetic metal found in hemoglobin that makes up about 4% of the content of human blood, is a strong indication that exposure of an area of the body to magnetism has an effect on that area.
Hence, magnetic field therapy is used by too many users to get significant benefits in relieving joint pain.
In simple terms, a magnet placed around the damaged joint attracts more blood to the area, increasing the supply of oxygen and nutrients to the damaged cells and speeding up the healing process.
It is also believed that because the magnetic field temporarily changes the molecular structure of blood in the area where they are transported, it flows more easily into cartilage and bone, which in turn increases the speed of healing.
Magnets are also believed to activate acupuncture points and meridians, causing a buzzing sensation in the chest and abdomen, which is a sign that the points are being stimulated. Some acupuncturists are now replacing needles with permanent magnets, as they are painless and treatment can be continued after consultation.
Biomagnetic therapy is recognized as a suitable alternative treatment for those suffering from fibromyalgia, a term used for generalized muscle pain but not joint pain. Recent research has found that magnetic therapy reduces the intensity of fibromyalgia pain to a point that is "clinically significant."
So, in summary, biomagnetic therapy provides "clinically significant" analgesic benefits for those suffering from joint and muscle pain.
