    Magnetic Storm This video is about the Earth’s magnetic force and its wavering. The molten iron in the earth creates the magnetic force around the earth. The magnetic force protects the earth‚ making it possible for life to exist on the planet‚ unlike other planets with weaker magnetic forces. Recently‚ though‚ scientists have discovered that the magnetic field seems to be faltering. The magnetic force starts near the South Pole and extends around the earth close to the North Pole and shields
