<p>Provided is a magnetically driven power-saving blower that is capable of stably blowing air with a simple structure, or an electricity generator that is capable of inducing stable generation of electricity with a simple structure. Either a permanent magnet (3) is supported by each of rotary fins (2), or a magnetized section (4) is provided on each of the rotary fins (2), and stationary core coils (5) are arranged along the rotational trajectory of the permanent magnets (3) or the magnetized sections (4) of the rotary fins (2). Magnetic repulsion between cores (5'), said cores being magnetized by energizing the coils (6) of the core coils (5), and the permanent magnets (3) or the magnetized sections (4) of the rotary fins (2) and magnetic attraction between the cores (5'), said cores being unmagnetized by not energizing the coils (6) of the core coils (5), and the permanent magnets (3) or the magnetized sections (4) of the rotary fins (2) are utilized to impart a turning force to the permanent magnets (3) or the magnetized sections (4) and thus to impart said turning force to the rotary fins (2).</p> |
