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 θ 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 θ . what os the radius of the smaller semicircle ?

Figure (a) shows two wires, each carrying a current. Wire 1 consists of a circular are of radius R and two radial lengthsit carries current it=20A in the direction indicated. Wire 2 is long and straigth it carries a current i2 that can be varried and it is at distance R/2 from the centre of the are. The net magnetic field B→ due to the current is measured at the center of curvature of the are Figure (b) is a plot of the component of B→ in the direction prependicular to the figure as a function of current i2 What is the angle subtended by the arc ?
