Resumen en inglés In this study, the effect of magnetoliydrodynamic (MHD) on natural convection flow from a horizontal circular cylinder in the presence of radiation has been investigated. The governing boundary layer equations are converted into non-dimensional partial differential equations by using the suitable transformation and then solved numerically by employing an accurate implicit finite difference scheme known as Keller-box method. We presented the influence of emerging non-dimensional parameters namely the MHD parameter M with combination of surface heating parameter θw and radiation-conduction parameter Rd on velocity and temperature profiles, skin friction coefficient and Nusselt number through graphs and tables. It is observed that the Lorentz force reduces the velocity, skin friction coefficient and Nusselt number. Moreover temperature increases in the presence of MHD effect. The streamlines and isotherms reflect some attractive flow patterns which show that magnetic parameter M and radiation parameter Rd have deep influence on these fluid and heat flow patterns
