A linear motor in which permanent magnets are bonded and the central yoke is equipped with a slidable movable coil that generates a magnetomotive force in the longitudinal direction, wherein both ends of the central yoke are provided with magnetic flux correction coils, and the correction coils are provided at both ends of the central yoke. A linear motor characterized in that a magnetic flux is generated in a direction that cancels the magnetic flux generated by the moving coil by passing a current through the linear motor.
