Problem 82

Magnetic field due to current in a straight 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 1a, 02 is given by B1a2 = m0 I 4p L L -L sin u r2 dy, where m0 is a physical constant, a 7 0, and u, r, and y are related as shown in the figure. a. Show that the magnitude of the magnetic field at 1a, 02 is B1a2 = m0 IL 2p a2a2 + L2 . b. What is the magnitude of the magnetic field at 1a, 02 due to an infinitely long wire 1LS _2?
