ABSTRACT:
A rotating apparatus includes a separating member, at least one movable magnet, and at least one passive magnet. The separating member is made of a nonmagnetic material, and interposed between the movable magnet and the passive magnet. The movable magnet is relatively shifted from the separating member along one surface of the separating member, and N-pole and S-pole of the movable magnet are arranged along the one surface of the separating member. The passive magnet is placed on the other surface of the separating member, and coupled with the movable magnet by magnetic force. When the movable magnet and the separating member are shifted relatively to each other, the passive magnet is shifted along the movable magnet and rotated on the other surface of the separating member.
