Abstract
A system may include a magnetic shape memory (MSM) element having a long 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 first solenoid, where a longitudinal axis of the first solenoid is positioned at a first angle relative to the long axis of the MSM element. The system may also include a second solenoid, where a longitudinal axis of the second solenoid is positioned at a second angle relative to the long axis of the MSM element and at a third angle relative to the longitudinal axis of the first solenoid, where the longitudinal axis of the first solenoid and the longitudinal axis of the second solenoid are not parallel.
Claims21
A system comprising:
- a magnetic shape memory (MSM) element having a long axis that extends from a first end of the MSM element to a second end of the MSM element;
- a first solenoid, wherein a longitudinal axis of the first solenoid is positioned at a first angle relative to the long axis of the MSM element;
- and
- a second solenoid, wherein a longitudinal axis of the second solenoid is positioned at a second angle relative to the long axis of the MSM element and at a third angle relative to the longitudinal axis of the first solenoid, wherein the longitudinal axis of the first solenoid and the longitudinal axis of the second solenoid are not parallel.
A system comprising:
- a magnetic shape memory (MSM) element having a long axis that extends from a first end of the MSM element to a second end of the MSM element;
- a first solenoid, wherein a longitudinal axis of the first solenoid is positioned at a first angle between 30° and 60° relative to the long axis of the MSM element;
- and
- a second solenoid, wherein a longitudinal axis of the second solenoid is positioned at a second angle between 30° and 60° relative to the long axis of the MSM element and at a third angle between 60° and 120° relative to the longitudinal axis of the first solenoid, wherein the longitudinal axis of the first solenoid and the longitudinal axis of the second solenoid intersect at a point proximate to the MSM element.
A method comprising:
- applying a first alternating current (AC) signal to a first solenoid, wherein a longitudinal axis of the first solenoid is positioned at a first angle relative to a long axis of a magnetic shape memory (MSM) element;
- and
- applying a second AC signal to a second solenoid, wherein a longitudinal axis of the second solenoid is positioned at a second angle relative to the long axis of the MSM element and at a third angle relative to the longitudinal axis of the first solenoid, wherein the longitudinal axis of the first solenoid and the longitudinal axis of the second solenoid intersect at a point proximate to the MSM element, and wherein the first AC signal and the second AC signal produce a combined rotating magnetic flux at the point.
