Verified by Toppr

Electrons flowing towards west means that the current in the wire is flowing towards the east. Thus the magnetic field at a point above it, in accordance with the Fleming's Right Hand Rule, is towards south, which is same as the direction of Earth's magnetic field at the point.
Hence the compass will not deflect and point towards North.
