Unsteady MHD micropolar fluid flow with Hall current has been studied numerically. These study are mainly based on the non-similarity approach. Hall current effects on two dimensional unsteady MHD micropolar fluid flow over a continuously moving vertical porous plate under the action of strong magnetic field is investigated. In this analysis the hall current in the momentum equation are considered for high speed fluid flows and the level of concentration of foreign mass have been taken very high. The system of equations have transformed by usual transformation into a non-dimension form then dimensionless momentum, angular momentum and temperature equations are solved numerically by explicit finite difference technique with the help of a computer programming language Compaq Visual Fortran 6.6a. The results of these study have discussed for the different values of the well known parameters with different time step.
