According to the right-hand rule, if a current-carrying wire is placed vertically and perpendicular to the Earth's magnetic field, the force acting on each electron will be perpendicular to both the direction of the current and the magnetic field, resulting in a force directed eastward. Thus the wire will experience a force in the horizontally towards the east direction.
