The present disclosure relates to a magnetically geared apparatus. In an example the magnetically geared comprises: a first mover comprising a plurality of first permanent magnets; a stator; a second mover; and a flux shield aligned with the first plurality of permanent magnets for attenuating magnetic flux. One of the stator and the second mover comprises a plurality of pole pieces and is positioned between the first mover and the other of the stator and the second mover. The first mover, the stator and the second mover are aligned in a first direction, and wherein the flux shield is spaced from the plurality of first permanent magnets in a second direction perpendicular to the first direction by a nonmagnetic region, thereby attenuating magnetic flux in the second direction.
