In the figure below, two circular arcs have radii a = 13.6 cm and b = 10.0 cm, subtend angle θ = 74.0∘, carry current i = 0.260 A, and share the same center of curvature P. What is the magnitude and direction of the net magnetic field at P? (Take out of the page to be positive. Indicate the direction with the sign of your answer.) T
