To provide a drive unit for amplifying a magnetic force, which sandwiches faces of both N and S poles of a permanent magnet having a strong magnetic force, between core edges of two electric magnets, arranges one or more permanent magnets having a strong magnetic force under the previously described permanent magnet so as to repel each other, and thereby generates strong drive force with small power.

The drive unit for amplifying the magnetic force is disclosed, which sandwiches the faces of both N and S poles of the permanent magnet having the strong magnetic force, between the core edges of two electric magnets, arranges one or more permanent magnets having the strong magnetic force under the previously described permanent magnet so as to repel each other, and thereby generates the strong drive force with small power.
