PURPOSE: To provide a device for moving an object capable of moving a running body in a new, three-dimensional motion including vertical motion.

CONSTITUTION: Magnetic poles of an electromagnet 21 are switched, from (a) to (b) in Figure, to attract it to an electromagnet 23 by jumping up a grinding section 12, realizing the condition shown in (e). The above step is repeated, to make a running body 10 run in a field 20.
