Paracelsus believed that he could use a magnet to draw disease out from a person, transfer it to the ground, and thus cure the patient. Later practitioners believed that a sick person could regain his health by sleeping with head and feet oriented north to south so as to be in line with the earth’s magnetic poles. Laputa, the saucer-shaped floating island visited by Gulliver in his travels, was propelled by the attracting or repelling forces of a large magnet imbedded in the center of the island. In recent years magnetism has similarly been called on to account for some of the peculiar maneuvers allegedly performed by UFOs. In the world of flying saucers an all-purpose electromagnetic (E-M) force, unknown to earth scientists, is supposed to be able to produce light and heat, disturb a compass, render an object radioactive, stop a wrist watch without damaging the man who wears it, interfere with the functioning of radio and TV sets, turn out the lights of automobiles, stop the action of gasoline engines, and aid in the creating of artificial gravitational fields (G-fields) around extraterrestrial spaceships.
