Abstract
An actuation apparatus may include a magnetic shape memory (MSM) element configured to contract locally at a portion of the MSM element in response to local exposure to a magnetic field distribution component that is substantially perpendicular to a longitudinal axis of the MSM element. The apparatus may further include a plurality of conductive coils laterally offset from the MSM element. Central axes of each conductive coil of the plurality of conductive coils may be substantially parallel to a longitudinal axis of the MSM element.
