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 ℓ 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....
