Record the label of the diagram (a, b, c, or d) where the contribution to the mag netic field at the origin from Id vector is the greatest. The dashed circle is shown to help you evaluate the distance from the origin. Select One of the Following: (aAnswer) Figure (a) (b) Figure (b) (c) Figure (c) (d) Figure (d) (e) Cannot tell. 1 (a) (b) (c) (d) I I I I Solution Figure (a) has largest magnetic field at the origin, because the angle between the displacement vector and the cur rent element is closest to 90 where the sine function is maximum. Total Points for Problem: 1 Points 2 Solution to Lab Quiz Problem 17.2(Direction of Current Element) Problem: The drawing to the right shows a wire carrying current I in the direction indicated. Whatdirection indicated....
