In the Figure, a wire is bent into the shape of a straight wire and a circle, with a circular loop of radius R = 3.4 cm and two long straight sections. The loop center coincides with %3D the origin of the coordinate system as shown. The straight sections are parallel to x-axis. The wire carries a l = 3.6 A current, as shown. Calculate the magnitude and the direction (into or out of the page) of the magnetic field at the origin. (Choose out of the page as the positive z-direction and express the magnetic field by using the sign of the result, which must be in multiples of 10 5 Teslas and include 2 digit after the decimal point. That means if you get a result of a 9.22 x 10 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 tpe -9.22 in the answer box.
