This paper considers the nonlinear boundary value problem (BVP) for the electrohydrodynamic flow of a fluid in an ion drag\r\nconfiguration in a circular cylindrical conduit. The velocity field was solved using the new homotopy perturbation method\r\n(NHPM), considering the electrical field and strength of the nonlinearity. The approximate analytical procedure depends only\r\non two components and polynomial initial condition. The analytical solution is obtained and the numerical results presented\r\ngraphically. The effects of the Hartmann electric number Ha and the strength of nonlinearity a are discussed and presented\r\ngraphically.We also compare this method with numerical solution (N.S) and show that the present approach is less computational\r\nand is applicable for solving nonlinear boundary value problem (BVP).
