Answer: The direction of force will be towards the east

Explanation: using Fleming's left hand rule. All the three fingers must be perpendicular to each other

As we align our middle finger in the direction of current (opposite direction to the motion of electron) and forefinger in the direction of magnetic field. Then thumb shows the direction of force.

East

this is because of Fleming left hand rule

according to this rule in this condition the electrons move towards north the the current flows toward south

and

the magnetic field is towards downward direction

then

our index fingure point towards downward

our middle points south and thumb points towards east
