The Biot-Savart law gives the magnetic field due to a very short segment of current I: dB 4 Ho I dsxî p2 where ds is a vector that points in the direction of the current with magnitude equal to the length of the smal segment and r is the vector from the small current segment to the point P where you want to find the magnetic field. Let 7 = -2.5 m ĵ and dš = (–0.04 î – 0.03 î) m and I = 4A What is the magnetic field dB at point P due to just the small wire segment ? (The Biot-Savart law holds only if the segment ds is infinitetessimally small but should be a good approximation here since ds
