<P>PROBLEM TO BE SOLVED: To provide an electromagnetic driving apparatus in which a coil 14 is located in a relatively movable way to a magnetic field so as to intersect the magnetic field and a drive current i is supplied to the coil 14 to relatively move the coil 14 with respect to the magnetic field, the electromagnetic driving apparatus efficiently supplying the drive current i or a drive voltage to the coil 14 to thereby prevent a wasteful electric loss from being produced. <P>SOLUTION: The drive current i (or drive voltage) is supplied only to part of the coil 14 which intersects the magnetic field. Since no current flows to other parts than the part of the coil 14 intersecting the magnetic field, the possibility of production of wasteful electric loss in the other parts is precluded. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
