Direct numerical simulations are performed to study turbulent Rayleigh-B\'{e}nard convection in a vertical cylindrical cavity with uniform axial magnetic field. Flows at high Hartmann and Rayleigh numbers considered. The calculations reveal that, similarly the behavior observed strong rotation, flows field develop central vortex, while heat transfer is suppressed.
