PURPOSE: To obtain a magnet toy enabling a large magnetic body to be moved with a small force by bringing another magnetic body close to a floating running body with the mounted bar-shaped magnetic body with a plurality of attracted magnetic bodies.

CONSTITUTION: A bar-shaped magnetic body 2 with a plurality of attracted magnetic bodies 1 is mounted on a floating running body 3. When the pole-N of another magnetic body 6 is brought close to the pole-N 4 of the bar-shaped magnetic body 2, then the poles are repulsed to each other, and so the floating running body 3 starts running to a pole-S 5 at the other end of the bar-shaped magnetic body 2. When the pole-S of another magnetic body 6 is brought close to the pole-S 5 of the bar-shaped magnetic body 2, then the floating running body 3 starts running in the counter direction. When the switching of the pole-N and the pole-S to each other is performed by a battery or the like, then a toy enabling a slender ship floating on water to be moved is formed.
