The current-carrying wire loop in Fig (a) lies all in one plane and consists of a semicle of radius 10.0 cm, a smaller semicicle is rotated out of that plkane by angle `theta` until it is perpendicular to the plane [Fig.(b)]. Figure (c) gives the magnitude of the net magnetic field at the center of curvature versus angle `theta` . what os the radius of the smaller semicircle ?
