In this paper, the limit size of a magnetic micro - machine using the magnetic torque was examined. This machine rotates according to a magnetic torque and is promoted. The limit of the miniaturization of the machine was examined by requesting the relation between a magnetic torque and the load torque. In the case of the rotating and driving magnetic micro-machine, the driving force and the drag decrease at the same rate. Therefore, the magnetic micro-machine can swim even if the machine becomes miniaturization.
