The current-carrying wire loop in the figure on the left lies all in one plane and consists of a semicircle of radius 10 cm, a smaller semicircle with the same center, and two radial lengths. The smaller semicircle is rotated out of that plane by angle theta, until it is perpendicular to the plane. The figure on the right gives the magnitude of the net magnetic field at the center of curvature versus angle theta. The vertical scale is set by Ba = 46.960 mu T and Bb = 63.484 (c)mu T. What is the radius of the smaller semicircle?

Figure 1: CRT with coils in Helmholtz configuration. The hot cathode emits electrons which are then accelerated through potential difference Vacc. When the electrons enter the magnetic field B, which is perpendicular to their velocity, they move on a circular path with radius r. The magnetic field is due to coils in Helmholtz configuration (2 coils separated distance that equals their radius). The magnetic field due to one of the coils with radius R, at a point on the axis distance z away from the center of the coil, was found using the Biot-Savart law: HOIR?N B1 2(R2 + z2)ž
