A wire is oriented along the z-axis, initially with no current in the wire. A moving electron is traveling along the x-axis in the positive direction. When the electron reaches the coordinate x = 4 m, a current in the wire suddenly is turned on, flowing in the +z direction. What is the direction of the magnetic force exerted on the electron at that moment: +z or -z or +x ?
