heal.abstract	The electromagnetically driven liquid metal flow in a toroidal duct of a square cross-section is studied numerically searching for the critical Reynolds (Re) and Hartmann (Ha) numbers where transition occurs. Results are reported for Ha up to 500, building a transition map of critical Reynolds and Hartmann numbers and showing two distinct regimes of transition signified by the destabilization of the secondary flow: The first, for Ha < 18, where the Lorentz force is balanced by fluid momentum diffusion and the second, for Ha 18, where it is balanced by fluid inertia. In both cases, the destabilization of the secondary flow occurs primarily near the concave sidewall. For Ha 18 the transition follows approximately the relationship Re = 16.803 Ha1.43 for values of Re and Ha in the range 80 < Re/Ha < 224.	en
