All segments of the wire produce magnetic fields at P 2 that are out of the page. According to the Biot-Savart law, the magnitude of the field any (infinitesimal) segment produces at P 2 is given by dB i r dx = µ θ 0 2 4 π sin where (the angle between the segment and a line drawn from the segment to P 2 ) and
