It rotates once on its axis for each revolution i.e., its rotation is synchronous so that it always keeps the same face toward Saturn and always leads with the same face in its orbit.
If the resultant moments of these domains are randomly oriented, the object as a whole will not display magnetism, but an externally applied magnetizing field will, depending on its strength, rotate one after another of the domains into alignment with the external field and cause aligned domains to grow at the expense of nonaligned ones.
Some of the sculptures on display are rotating, its shadows slowly dancing across the walls.
