A conductor consists of a circular loop of radius R = 1.60 cm and two straight, long sections, as shown in Figure below. The wire lies in the plane of the paper (xy-plane) and carries a current i = 9.30 mA. Find the magnitude and direction (into or out of the page) of the net magnetic field at the center of the loop, point C. (Choose out of the page as the positive z-direction and express direction of the magnetic field by using the sign of the result, which must be in multiplies of 10 -7 T and include 2 digit after the decimal point. That means if you get a result of a 9.22 and the direction of the field is out of the page, just type 9.22 or if you find the direction of the field as into the page, just type -9.22 in the answer box. Take vacuum permeability µ 0 = 4π x 10 -7 T /A 2 and π=3.14.)
