PURPOSE: A non-directional magnetic field generating device is provided, which measures the same magnetic field density value regardless of a measuring direction at the same distance from the center of a regular polyhedron. CONSTITUTION: Magnets or current bands are attached on surfaces of a dodecahedron. In case of magnets, an outward polarity of respective surfaces is either one of an N or S polarity. In case of current bands, a winding direction of a current bands to be attached on each surface is the same. The magnets or current bands are placed at the center of respective surfaces so as to minimize a directivity of a magnetic field.
