Magnetic linear actuator (MLA) and use. The MLA includes a driver portion with motor and rotating mount with a first magnet (M1) having poles aligned in a plane, and an actuator portion, having a frame with a second magnet (M2) proximate to a first end of the frame with a specified pole facing the frame's center, and a third magnet (M3) proximate to a second end of the frame with the specified pole facing the frame's center. The frame holds M2 and M3 collinear with M1, in the plane, and on opposite sides of the M1, and is constrained to move along an axis collinear with M1, M2, and M3. During operation, the motor rotates M1 through a first orientation where M1 attracts M2 and repels M3, then a second orientation where M1 repels M2 and attracts M3, in response to which the frame moves back and forth, e.g., reciprocates.
