An actuator assembly includes a coil moveably positionable in a magnetic field generated by a magnet assembly, each of the coil and the magnet having substantially only one side facing the other. A magnetized field-shaping element is provided for shaping the magnetic field such that the magnetic field is substantially perpendicular to the direction of the electrical current for generating a force in a first degree of freedom. Thus, the coil may easily be mounted, since it does not need to be enclosed by magnet poles.
