To eliminate a problem that a recent permanent magnet has high coercive force and high magnetic energy product and is variously studied to be used for a rotating device, but as known, the magnet has attracting and repelling forces, therefore, even when the magnet is intended to be rotated with repelling force by changing angle of same pole magnets, the magnet does not rotate because first action causes repelling but the next same pole repels oppositely and is not wound in the rotation direction, and even for attraction first action causes attraction but remaining attraction does not cause rotation.

This device is developed by employing attraction and magnetic force, and is constituted so that a fixing magnet 8 surrounds a half of a rotational magnet body 7 and the negative surface of the magnetic force is cut by using its entire positive surface. The rotational magnet body 7 generates motive power and rotates employing force balance between attraction and magnetic force, by considering that when a rotational magnet 6S pole approaches with attraction most closely to the top stage of a magnetic field central part 9 of the upper fixing magnet 8N pole, action of attraction sequentially drops magnet shafts 4 from the upper stage to the lower stage.
