Magnetic field therapy can be used in both diagnosing and treating physical and emotional disorders. This process has been recognized to relieve symptoms and may, in some cases, retard the cycle of new disease. Magnets and electromagnetic therapy devices are now being used to expel pain, facilitate the healing of broken bones, and counter the effects of stress.

  The world is surrounded by magnetic fields: some are generated by the earth's magnetism, while others are generated by solar storms and changes in the weather. Magnetic fields are also created by everyday electrical devices: motors, televisions, office equipment, computers, microwave ovens, the electrical wiring in homes, and the power lines that supply them. Even the human body produces subtle magnetic fields that are generated by the chemical reactions within the cells and the ionic currents of the nervous system.

  Recently, scientists have discovered that external magnetic fields can affect the body's functioning in both positive and negative ways, and this observation has led to the development of magnetic field therapy.
