Chapter 29, Problem 064 In the figure, a closed loop carries current i = 93.9 mA. The loop consists of two radial straight wires and two concentric circular arcs of radii 1.70 m and 3.83 m. The angle 0 is 1.04 rad. What are the (a) magnitude and (b) direction (into or out of the page) of the net magnetic field at the center of curvature P?
