The influence of the magnetic field on the boundary layer separation of a two‐dimensional incompressible flow of a conducting fluid subject to a non‐slip boundary condition is studied. It is found that the key factor differentiating this phenomenon from the hydrodynamic case is the angular velocity of the magnetic field at the boundary wall. The general equation governing the start of separation is illustrated by a class of flows generalizing the classical Hartmann one, where the physical meaning of the different terms is very clear.
