概要	This study aims to clarify the melting and solidification behavior of W under the intense magnetic field. In order to simulate the heat load, the Nd/YAG laser, which has almost flatten spatial profile and rectangular temporal profile, was irradiated on a W specimen. The power density of the laser was 3.12 GW/m2 and 3.9 GW/m2 and the pulse width was 3 [ms]. Helmholtz-like electromagnetic coils were applied for generating pulsed magnetic field. The magnetic density was also changed in the range from 0 to 4 [T] in this study. From observation of the light emitted from the heated W surface using a high-speed video camera and measurement of irradiation traces, the behavior of molten W and the effect of the magnetic field will be reported and discussed.
