Pretty sure you need to use the right hand grip rule.

a The right-hand screw rule gives us a south-pointing field at P from conductor m.

b A north-pointing field at P from conductor n.

c The resultant magnetic field due to the conductors is zero. The only field in existence at
that point would be that due to the Earth, whose direction is north.
