How Do Magnetic Fields Work?

Electromagnetic Impulses

Magnetic therapy makes use of the natural energy of magnetism to aid in the healing process, according to magnetictherapyinfo.com. The American Cancer Society (ACS) says proponents of magnetic therapy maintain that some cells and tissues in the body send off electromagnetic impulses of varying strengths. It is theorized that placing magnetic fields on wounded or damaged tissue can calm bodily disturbances and accelerate the body's natural ability to heal.

Negative Magnetic Fields

Proponents of magnetic therapy say the magnetic field created from the negative pole of the device is where its healing power lies. Negative magnetic fields fuel metabolism, increase the accessibility of oxygen to cells and produce a lesser amount of acid in the body. The alleged healing powers of these negative magnetic forces are also promoted as expediting the healing of cuts and infections while countering the potentially harmful effects of addictive drugs and toxins.

Magnetic Apparatus

Supporters assert that the use of magnetic rings, bracelets, necklaces and other such devices can help reduce arthritis and migraine pain, repair broken bones and reverse degenerative diseases (diseases in which the function of the impacted tissues or organs worsen as time goes on).
Magnets can also be inserted into belts or bands that are worn around the waist, ankle, knee or wrist.
Magnets are sometimes placed in blankets and sleeping pads that manufacturers claim can cure such ailments as back pain, fibromyalgia, rheumatoid arthritis, epilepsy and emphysema, among several others.

FDA Findings

According to the U.S. Food and Drug Administration (FDA), while magnetic therapy is generally believed to be safe, it is of no use for medical purposes.
The ACS says there has been a limited amount of scientific research into the therapeutic effects of magnets. In general, the results of clinical trials to date of static magnets (also known as constant magnets because the magnetic field remains unchanged) to reduce pain have been inconsistent.
