This paper presents an analytical study of the laminar flow of an electrically conducting viscoelastic fluid, known as Walters's liquid B-prime, past an infinite porous flat plate to a step function change in suction velocity in the presence of a transverse magnetic field. Results of an investigation of the effects of various magnetic field parameters on the velocity field and shearing stress showed that, as the magnetic field parameter M increases, the values of the fluid velocity decrease for fixed values of the elastic parameter K; however, the fluid velocity increases with an increase in the value of K. The values of the shearing stress decrease with an increase of M and time for a fixed value of K; with an increase of K, the shearing stress decreases for small values of M but increases for large M values.
