This decline has also been determined by measurement of decrease of north-south orientation of magnetic deposits which have occurred at known times in history. However, the need for the Earth's magnetic force to maintain health was not recognized until the advent of modern space travel. In addition, scientists have discovered that die-outs of higher vertebrates have occurred with magnetic field decline and reversals. This has been determined by studying core samples from the ocean floor. References to the early use of the force of magnetism in the healing arts are found in most civilizations o fthe world.

Ancient Hindu scriptures, Egyptian and Persian history, and Tibetan monk practices indicate therapeutic lodestone usage.

Mesmer was particularly noted for successful treatment of a variety of ills in the mid 1700's. The magnetic field produced by permanent magnets is a safe natural energy source.
