ABSTRACT:
A force generating apparatus having spacings through which magnetic fluxes are traveled, a magnetic circuit including two permanent magnets supplying magnetic fluxes to the spacings and a conductor disposed in the direction perpendicular to the magnetic fluxes in the spacings is comprised of two pair of permanent magnets of the same size, and a member for disposing the two pair of permanent magnets such that magnetic axes thereof are opposed in parallel to each other, wherein a total sum of magnetic moments caused by the two pair of permanent magnets is cancelled out. Therefore, the force generating apparatus can be prevented from producing a harmful torque even if an external magnetic field acts thereon.
