The magnetic field generated by a current flowing from east to west in a wire points vertically upwards along the z-axis when observed from a point directly above the wire. This conclusion is derived using the right-hand rule, which dictates the orientation of the magnetic field relative to the direction of current flow. The right-hand rule is a fundamental principle in electromagnetism that helps visualize the relationship between current direction and magnetic field orientation.
