Motor Coil Vertical

When the coil moves into the vertical postition (as long as the current is still flowing) the forces acting on the wires remain :

horseshoe magnet with a single coil of wire carrying DC current with forces shown

The forces act against each other: the coil will stop rotating! How then can a real motor keep going in the same direction? And how does it not twist its wires into a mess?
