摘要	In order to investigate the magnetic force distribution, flow field distribution and joule heat distribution under the pulsed magnetic field (PMF), transient numerical simulation was carried out. Results show that the magnetic pressure force appears in the inner of the melt, while the magnetic pull force and the magnetic pressure force appear alternately in the exterior of the melt, which is caused by the skin vortex current. The axial direction magnetic force results in the convection Of the melt. The radial direction magnetic force produces vibration of the melt. The vibration will diffuse and superpose to produce the pressure wave. Finally, the fluctuation of the melt is caused by the pressure wave. The joule heat produced by pulsed magnetic field concentrates near the surface of the melt in the pulse applying period. (C) 2009 Elsevier Ltd. All rights reserved.
