AB - The main aim of the present work is to highlight the significances of  periodic mixed convection flow and heat transfer characteristics along the  surface of magnetized cone by exerting magnetic field exact at the surface of  the cone. The numerical simulations of coupled non-dimensional equations are  computed in terms of velocity field, temperature and magnetic field  concentration and then used to examine the periodic components of skin  friction, τw, heat transfer, qw, and current density, jw, for various  governing parameters. A nice periodic behavior of heat transfer qw is  concluded for each value of mixed convection parameter, λ, but maximum  periodicity is sketched at λ = 50. It is also computed that the lower value  of magnetic Prandtl number γ = 0.1 gets poor amplitude in current density but  highest amplitude is sketched for higher γ = 0.5. The behavior of heat and  fluid-flow in the pres­ence of aligned magnetic field is associated with the  phase angle and amplitude of oscillation. It is also noted that due to the  increase in magnetic force parameter, ξ, there are wave like disturbances  generate within the fluid layers. These disturbances are basically  hydromagnetic waves which becomes more prominent as the strength of magnetic  force parameter is increased.
