This paper presents velocity profile measurements of an oscillatory pipe flow of magnetic fluid by Ultrasonic Velocity Profile (UVP) method. Experiments are performed at Reynols number Re=367, defined by mean velocity amplitude and a pipe diameter, and non-dimensional angular frequency II'=4.76. It is shown that velocity amplitude increases in the center of a pipe and decreases in the near wall region under non-uniform magnetic field. The comparison of measured data under non- magnetic field with those obtained from the theory of Newtonian-fluid reveals that noticeable discrepancies exist between them.
