PURPOSE : A method for manufacturing a carbon health magnet is provided to manufacture a healthful carbon magnet by using a non-metallic material.CONSTITUTION : An octagon diamond or a hexagon graphite is inserted into major carbon in a furnace at a temperature higher than 1200 degrees. One or two of a samarium, cerium, and praseodymium are inserted to a coercive rare-earth metal. RFeO3 is formed to have coercivity and respective ions are arranged on a semi-horizontal plane in a Ferri technique. A magnetic flux of the electric furnace is set to be higher than 500 gauss. And a carbon magnetic rock is processed in a furnace at a temperature higher than 910 degrees by a ferrite hard technique, such that the coercivity of the resultant material is increased more than 10 times.?
