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

Two very long wires carry current as shown. What is the direction of the total magnetic field at point 1 ? Up and Right Up and Left Down and Right Down and Left
The current-carrying wire loop in the figure on the left lies all in one plane and consists of a semicircle of radius 18 cm, a smaller semicircle with the same center, and two radial lengths. The smaller semicircle is rotated out of that plane by angle θ, until it is perpendicular to the plane. The figure on the right gives the magnitude of the net magnetic field at the center of curvature versus angle θ. The vertical scale is set by Ba = 25.620 μT and Bb = 35.444 μT. What is the radius of the smaller semicircle?
