We study the Dp-brane dynamics near NS5-branes with constant electromagneticfield. In the framework of effective Dirac-Born-Infeld action, we investigatethe effect of the electromagnetic field on the Dp-brane dynamics. The radialmotion of the Dp-brane on the transverse directions of NS5-branes can be mappedto a rolling tachyon in a constant NS $B_{\mu\nu}$ background. In the nearthroat region, the classical motion can be identified with the rescaledhairpin. After constructing the boundary state of the rescaled hairpin, wediscuss the closed string emission of the Dp-brane and find that the energy ofthe closed string emission is always finite in the presence of electric field.Taking winding strings into account, the emitted energy is divergent,indicating that the emitted winding strings carry away most of energy.Comment: 17 pages, Latex; references added;v3, typos correcte
