Abstract
A system may include a magnetic shape memory (MSM) element having a longitudinal axis that extends from a first end of the MSM element to a second end of the MSM element. The system may further include a rotatable permanent magnet configured to rotate around an axis of rotation and positioned proximate to the MSM element. The system may also include a first solenoid having a first solenoid axis directed at the rotatable permanent magnet. The system may include a second solenoid having a second solenoid axis directed at the rotatable permanent magnet. A method may include applying a first alternating current (AC) signal to the first solenoid and a second AC signal to the second solenoid to cause the rotatable permanent magnet to rotate.
