Abstract:	This work investigates the consequence of hall current on the boundary layer along a stretching sheet in the occurrence of magnetohydrodynamics, heat transfer and viscous dissipation. In the direction of the flow, a uniform transverse magnetic field is applied. Here, the controlling equations are modified into nonlinear ordinary expressions, implementing the similarity transformation. Validation is accomplished by applying the MATLAB bvp4c skill. We then visually display the impact of varied parameters by introducing temperature and non-dimensional velocity into the problem. Moreover, it is found that the relevant parameters significantly affect the flow patterns and other important physical quantities by organizing and categorizing their effects on the coefficients of skin-friction and heat transfer rate using the Nusselt number, which are of concrete relevance. Our study shows that increasing the Hall current parameter results in an enhanced primary velocity flow pattern, accompanied by a reduction in secondary velocity and temperature flow patterns.
