PROBLEM TO BE SOLVED: To enable driving a movable body by supplying a low voltage large current caused by the interaction between currents of a movable current line and drive force current lines and reciprocally exchanging electrical power and mechanical power. SOLUTION: On one side or on both sides of a movable current line 11, groups of drive force current lines are so formed that one group of drive force current lines may be in the same direction as the movement direction X of the movable current line 11, and the other group of driving force current lines may be in the opposite direction. The drive force current lines 12 which are located in the front of the progressing direction of the movable current line 11 that progresses and which are in the same direction as the movable current line 11 are attractive current lines 12B which attract the movable current line 11 and give it attractive drive force and those which are located at the back of the progressing direction of the movable current line 11, which are in the opposite direction to the movable current line 11 are thrust current lines 12A which repel the movable current line 11 and give it a drive thrust. When there is one or more attractive current lines 12B, one or more thrust current lines 12B, and one or more movable current lines 11 which are all in the same direction, the working force of the drive force current lines 12 on the movable current lines 11 are effective working force and the attractive current lines 12B and the thrust current lines 12A give drive force to the movable body. |
