Abstract: Use energy resource from gravity (magnetic force) of permanent magnet and apply the principle of “Magnetic field, magnetic force of permanent magnet was holding (stopped), can not get out of the closed environment of a metal with very high magnetic permeability”, along with applying laws of physics and the physical-chemical properties different types of material in nature. Eternal Engine invented in the form of a cylinder system, operated by the innovative method that closed-open automatically the fixed magnetic force of permanent magnets.
