PURPOSE: To obtain a magnet toy which can be run on a floating running body by mounting another magnetic body to be repulsed, guided, or attracted to a bar-shaped magnetic body with a plurality of attracted magnetic bodies, on the floating running body.

CONSTITUTION: When on a floating running body 3 put on the pole-N 4 of a bar-shaped magnetic body 2 with a plurality of attracted magnetic bodies 1, the pole-N of another magnetic body 6 directed to the bar-shaped magnetic body 2 is mounted, then the pole is repulsed, 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 on the floating running body 3 at the pole-S 5 of the bar-shaped magnetic body 2, the pole-S of another magnetic body 6 directed to the bar- shaped magnetic body 2 is mounted, then the floating running body 6 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 ship floating on water to be run is formed.
