Methods and apparatus for enabling a coil to be used to provide a net force along more than one axis are disclosed. According to one aspect of the present invention, an actuator includes a magnet assembly and a coil assembly. The coil assembly moves at least partially within the magnet arrangement, and includes a top coil half and a bottom coil half. The top coil half and the bottom coil half are independently controllable such that a first current applied to the top coil half may be independently applied from a second current applied to the bottom coil half.
