This paper describes a numerical analysis of flow in an induction-type electromagnetic pump. Laminar and turblent flows in a conducting fluid between two coaxial cylindrical walls to which were applied an azimuthally traveling sinusoidal magnetic field are investigated numerically. In order to consider the demagnetizing effect quantitatively, induced magnetic fields due to induced currents are calculated based on the Biot-Savart's law. Several characteristic curves are obtained from numerical results. They are characterized by the Hartmann number, magnetic Reynolds number, azimuthal pressure gradient, pole pitch and curvature of the channel. Influence of these parameters on the flow are discussed in detail.
