Unformatted text preview: Solution for Lab Quiz 17 Magnitude of Magnetic Field Solution to Lab Quiz Problem 17.1(Relative Magnitude of Current Elements Placed Around Circle) Problem: In the figures below, all the current elements, Id vector ℓ , have the same magnitude. 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: (a-Answer) 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.
