Part A Learning Goal: To practice Problem-Solving Strategy 29.1 The magnetic field of a current. The picture below shows an incomplete pictorial representation of the situation described in this problem. For symmetry reasons, the A long wire carries current 1. The wire is straight except coordinate system is chosen so that its origin coincides with the point P at which you want to calculate the magnetic field, and the wire for one square-shaped "half-loop" KLMN as shown. ( lies in the xy plane. The z axis is perpendicular to the page, pointing out of to the page. Figure 1)Find the magnitude and the direction of the As outlined in the strategy above, the wire has been divided into very short segments. For clarity, only one of these segments, segment k magnetic field B at point P. Assume that d is a known quantity. of length Ax, is shown in the diagram. In what direction is the magnetic field Bi at P due to segment k alone? Segment k M Ar I J K N P d - View Available Hint(s) By at P is parallel to the x axis. O BK at P is parallel to the y axis. O Bk at P is parallel to the z axis. O BY at P lies in the xy plane, neither parallel to the x axis nor to y axis. O Bk at P lies in the yz plane, neither parallel to the y axis nor to z axis. BK at P lies in the xz plane, neither parallel to the x axis nor to z axis.
