Abstract
A system may include a magnetic shape memory (MSM) element having a first end and a second end, where a longitudinal axis of the MSM element extends from the first end to the second end. The system may further include a permanent magnet having a first pole and a second pole, where the first pole and the second pole are aligned perpendicularly to the longitudinal axis of the MSM element. The system may also include a first electromagnet directed to the first end of the MSM element and a second electromagnet directed to the second end of the MSM element.
Claims20
A system comprising:
- a magnetic shape memory (MSM) element having a first end and a second end, wherein a longitudinal axis of the MSM element extends from the first end to the second end;
- a permanent magnet having a first pole and a second pole, wherein the first pole and the second pole are aligned perpendicularly to the longitudinal axis of the MSM element;
- a first electromagnet directed to the first end of the MSM element;
- and
- a second electromagnet directed to the second end of the MSM element.
A system comprising:
- a magnetic shape memory (MSM) element having a first end and a second end, wherein a longitudinal axis of the MSM element extends from the first end to the second end;
- a permanent magnet configured to subject the MSM element to a magnetic field;
- a first electromagnet directed to the first end of the MSM element;
- a second electromagnet directed to the second end of the MSM element;
- and
- a controller configured to sweep a first power level through the first electromagnet and to sweep a second power level through the second electromagnet to cause continuous movement of a contracted portion of the MSM element along the longitudinal axis.
A method comprising:
- subjecting a magnetic shape memory (MSM) element to a magnetic field of a permanent magnet, wherein the MSM element has first end, a second end, and a longitudinal axis that extends from the first end to the second end;
- sweeping a first power level through a first electromagnet directed to the first end of the MSM element;
- and
- sweeping a second power level through a second electromagnet directed to the second end of the MSM element.
