PURPOSE: A magnetic force maximizing method using a repulsive force of a magnet is provided to fix the same polarities by dividing the magnet of limited thickness into two. CONSTITUTION: A magnet includes a protruded magnet(10), a holed magnet(14), and a male screw(17). A female screw(12) is prepared on a protruded unit(11) of the protruded magnet. The holed magnet includes a hole(16). The male screw fixes the protruded magnet and the holed magnet. When the holed magnet is moved, the N pole generates a magnetic force. A male screw hole(15) is prepared in the hole.
