ィ frgme I Suppose, there is an infinite current carrying wire lying along the z-axis as shown in the figure. A current / = 23 mA is flowing through the wire in the k direction. Two points P,(0, 3, 14) and P2 (0, - 3, 14) are shown in the figure. Here the coordiates are given in meters. Note: Here, positive sign of current means current flowing towards +k direction. And negative sign of the current means current flowing towards -k direction. a)Find the magnetic field in unit vector notation at point P, due to the infinite wire. x component of the magnetic field Give your answer to at least three significance digits.
