Plasma conductivity anisotropy is realized through the rotation transformation of the coordinate axis. By obtaining the magnetic field distribution, a conductivity anisotropic conductor model is established. The ability of target biasing in different bias modes under the J-TEXT divertor configuration to generate electric fields in the plasma and drive ExB drift is analyzed. Results show that the radial electric field is dominant, and the corresponding ExB drift is poloidal. A hybrid bias mode exhibits promising potential in widening the SOL and eliminating poloidal asymmetry.
