review text: Summary: Magnetic field effect on local entropy generation due to steady two-dimensional laminar forced convection flow past a horizontal plate was investigated numerically. The study was focused on the entropy generation characteristics and its dependence on various dimensionless parameters. The effect of various dimensionless parameters, such as Hartmann number \((Ha)\), Eckert number \((Ec)\), Prandtl number \((Pr)\), Joule heating parameter \((R)\) and the free stream temperature parameter \((\theta_\infty)\) on the entropy generation characteristics is analyzed. The dimensionless governing equations in Cartesian coordinates were solved by an implicit finite difference technique. The solutions were carried out for \(Ha^2=0.5-3, Ec=0.01-0.05, Pr=1-5\) and \(\theta_\infty =1.1 - 2.5\). It was found that the entropy generation increased with increasing \(Ha, Ec\) and \(R\). While, increasing the free stream temperature parameter and Prandtl number tends to decrease the local entropy generation.
