Imagine that in part E8, you had placed the compass due East of the wire. Draw two vector diagrams of the magnetic field felt by this compass: One with the current OFF and one with the current ON. Each diagram should show the magnetic fields from any relevant sources as well as a vector indiacating the total magnetic field. For this problem, assume that the current flows upwards (in diagram it is out of page).
