# Problem 3:A rabbit has eaten the foil shielding off of a power cable that carries aDC current of 1 0.41 A to the amplifier for your outdoor speaker system. The shieldedparts of the wire do not contribute to the magnetic field outside the wire. The unshieldedpart of the wire is x 0.022 meters long. Point A is exactly above the midpoint of theunshielded section, a distance x/2 above the wire. The current flows to the right as shown,which should be taken as the positive direction. The small length of wire, dl, a distance lfrom the midpoint of the unshielded section of the wire, contributes a differential magneticfield dR. at point AOtheexpertta.comPart (c) Select the limits of integration that will correctly calculate the magnetic fieldat A due io the current in the unshielded length of wire./--/2 to/-x/2V Correct!.
