PROBLEM TO BE SOLVED: To provide an interesting moving toy using a permanent magnet and to efficiently extract power developed therefrom. SOLUTION: The moving toy is composed of a driven magnet attached to a roller provided at a frame, and a driving magnet acting on the driven magnet. The driving magnet held in hand is brought close to or away from the driven magnet by changing positions or angles to rotate a roller for arbitrary motion, such as forward, backward, and rotational motion.
