The demands on actuating devices have steadily increased as technologies continue to develop. Ni-Mn-Ga is a magnetic shape memory (MSM) alloy that has a unique combination of properties which give it significant potential as an actuating material for future devices. Most research on Ni-Mn-Ga has been studying the effects of a uniform magnetic field when it is applied to a bulk sample of material. This research explores the use of a focused magnetic field on a specific location of a constrained sample. This localized actuation of the material allows for a new level of precision for MSM devices that was not previously possible. These results, coupled with rapid actuating response time and acceleration, make Ni-Mn-Ga an ideal candidate for actuating devices, particularly at a microscale.
