Magnetic field due to current In a stralght wire A long, straight wire of length 2L on the y-axis carries a current I. According to the Biot-Savart Law, the magnitude of the magnetic field due to the current at a point (a, 0) is given by B(a)- sin 0 dy, where uo is a physical constant, a> 0, and e, r, and y are related as shown in the figure. Ho IL a. Show that the magnitude of the magnetic field at (a, 0) is B(a) - 2m aVa + L b. What is the magnitude of the magnetic field at (a, 0) due to an infinitely long wire (L→ 0)?
