Magnetic therapy , or magnetotherapy is a pseudoscientific alternative treatment practice that involves the use of a weak static magnetic field, a form of electromagnetic radiation, produced by magnets permanent. This is similar to alternative therapeutic practices of electromagnetic therapy, which uses the same type of EM radiation, but is generated from electrically powered devices.
Practitioners claim that subjecting certain parts of the body to a weak EM field has beneficial health effects. These physical and biological claims are not proven and no effect on health or healing has been established. Although hemoglobin, a blood protein that carries oxygen, is weakly diamagnetic (when oxygenated) or paramagnetic (when deoxygenated) the magnet used in magnetic therapy many magnitude orders is too weak to have a measurable effect on blood flow.

Metode aplikasi
Magnetic therapy is the application of a weak static magnetic field to the permanent static of recognized health benefits. Different effects are assigned to different orientations of magnets.
Products include magnetic bracelets and jewelry; magnetic straps for wrists, ankles, knees, and back; shoe soles; mattress; magnetic blanket (quilt with magnet knitted into material); magnetic cream; magnetic supplements; plaster/fillings and water that has been "magnetized". Applications are usually performed by the patient.

The mechanism of action claimed
Perhaps the most common suggested mechanism is that magnets can increase blood flow in the underlying tissues. The field surrounding the magnetic therapy device is too weak and falls too quickly to affect hemoglobin, other blood components, muscle tissue, bone, blood vessels, or organs. A 1991 study on humans from static field strength to 1 T found no effect on local blood flow. Network oxygenation is also unaffected. Some practitioners claim that magnets can restore the "hypothetical" electromagnetic energy of the body, but there is no medically recognized equilibrium. Even in the magnetic field used in magnetic resonance imaging, which is many times stronger, no effect is claimed. If the body is strongly affected by weak magnets used in magnetic therapy, MRI will become impractical.
Benefits
Several studies have been conducted in recent years to investigate what role, if any, static magnetic fields can play in health and healing. Neutral study of magnetic therapy is problematic, since magnetization can be easily detected, for example, by tensile strength on iron objects (containing iron); because of this, blinding effective studies (where neither patients nor assessors know who received treatment compared with placebo) is difficult. Incomplete or insufficient blurring tends to exaggerate the effects of treatment, especially if the effect is small. Health claims about longevity and cancer treatment are unreasonable and are not supported by any research. More worldly health claims, most commonly about anecdotal pain relief, also lack the proposed mechanism and credible clinical studies are not promising.
Magnetic therapy has been promoted as a treatment for cancer and other diseases; The American Cancer Society states that "the available scientific evidence does not support this claim". According to the National Center for Complementary and Integrative Health, the study of magnetic jewelry has not demonstrated a proven effect on pain, nerve function, cell growth or blood flow.
A systematic review of magnetic therapy for all indications found insufficient evidence to determine whether magnetic therapy was effective for pain relief, as did the 2012 reviews focusing on osteoarthritis. Both reviews reported that small sample sizes, inadequate randomisation, and difficulties with concealment allocations all tend to study positive biases and limit the strength of conclusions.
Security
These tools are generally considered safe in themselves, although there are significant financial and opportunity costs for magnetic therapy, especially when treatment or diagnosis is avoided or delayed.
Reception
The worldwide magnetic therapy industry total sales more than a billion dollars per year, including $ 300 million per year in the United States alone.
The 2002 National Science Foundation's report on public attitudes and understanding of science notes that magnetic therapy is "completely unscientific." Some vendors make unsupported claims about magnetic therapy using pseudoscientific and new-age languages. Such claims are not supported by scientific and clinical research results.
Legal rule
Marketing of any therapy as an effective treatment for any condition is severely restricted by law in many jurisdictions unless all claims are scientifically validated. In the United States, for example, the US Food and Drug Administration regulations prohibit the marketing of any magnetic therapy product using medical claims, since the claim is unfounded.
