The net force is the vector sum of all forces acting on the object. In this case, the forces are acting in opposite directions, so we need to subtract their magnitudes to get the net force:

15 N (southward) - 10 N (northward) = 5 N (southward)

Therefore, the magnitude of the net force is 5 N, and the best choice is B.
