You should apply Fleming's left hand rule. Using your left hand:
1. point your middle finger in the direction of the conventional current i.e. the direction from +ve to -ve
2. point your index finger in the direction of the magnetic field i.e. from N to S.
3. Your thumb is now pointing in the direction of the force felt by the current in the wire.
If you were considering a dynamo or generator, you would do the same thing, but using your right hand. ("geneRIGHTor"
.
Note that this only works for conventional current, so we have to assume that the direction given in the question is indeed conventional.
