Abstract
In this paper, the magnetic fluid linear actuator is designed. Inside the small tube, magnetic fluid is shielded with thin rubber protector. The magnetic fluid activated by traveling pulses of magnetic field drags the water inside the actuator. The size and weight of the device because there is no gear type parts, we can do reduce. Furthermore, it could be operated without vibration and noise.


The iterative algorithm for the shape of magnetic fluid is presented by using nonlinear finite element method and Navier-Stokes equations. The computed curvatures of fluid under the magnetic field and the gravitational force are agreed well with photographic image. The dimension and electric configurations of the magnetic linear actuator are optimized and the results are compared with the measurements.
