Suppose you are facing a tall makeup mirror on a vertical wall. Fluorescent tubes framing the mirror carry a clockwise electric current. (i) What is the direction of the magnetic field created by that current at the center of the mirror? left right horizontally toward you horizontally away from you no direction because the field has zero magnitude (ii) What is the direction of the field the current creates at a point on the wall outside the frame to the right? left right horizontally toward you horizontally away from you no direction because the field has zero magnitude
