Abstract
A method of imparting motion includes contracting a portion of a magnetic shape memory (MSM) element in response to a magnetic field to form an indentation on a surface of the MSM element. The method further includes retaining a protrusion from a surface of a movable part at the indentation. The method also includes moving the movable part by changing a position of the indentation in response to a change in the magnetic field.
