A very long straight wire carries current 28 A. In the middle of the wire a right-angle bend is made. The bend forms an arc of a circle of radius 22 cm, as show. Determine the magnetic field at the center of the arc. What is the direction of the magnetic field? O left O into the plane of the computer screen O down O out of the plane of the computer screen O down and to the left O right B = T
