We study the holographic Schwinger effect with magnetic field at RHIC and LHCenergies by using the AdS/CFT correspondence. We consider both weak and strongmagnetic field cases with $B\ll T^2$ and $B\gg T^2$ solutions respectively.Firstly, we calculate separating length of the particle pairs at finitemagnetic field. It is found that for both weak and strong magnetic fieldsolutions the maximum value of separating length decreases with the increase ofmagnetic field , which can be inferred that the virtual electron-positron pairsbecome real particles more easily. We also find that the magnetic field reducesthe potential barrier and the critical field for the weak magnetic fieldsolution, thus favors the Schwinger effect. With strong magnetic fieldsolution, the magnetic field enhances the Schwinger effect when the pairs arein perpendicular to the magnetic field although the magnetic field increasesthe critical electric field.
