摘要:
An actuation apparatus may include a magnetic shape memory (MSM) element configured to compress locally at a portion of the MSM element in response to a perpendicular concentrated portion of a magnetic field. 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. The apparatus may also include at least one permanent magnet in proximity to the MSM element. The permanent magnet may generate a significant portion of the magnetic field. By successively applying, reversing, and reducing or eliminating electrical currents applied to the conductive coils, a position of the perpendicular concentrated portion of the magnetic field may be moved relative to the MSM element.
