A device is provided to increase magnetic force by calculating the difference between the space where relative force is applied and a marginal length of connecting force. A device includes base rings arranged into a triangle shape such that intermediate force is generated between forces generated in two end spaces. In the space of the angle of 20 degrees, forces are generated from two spaces in which first force is generated from the space of the angle of 32 degrees*32 degrees, and second force is generated from the space of the angle of 20 degrees.
