Use the Biot-Savart Law to determine the magnitude and direction of the magnetic field at the common center (P) of two concentric wire arcs of radii, b=0.6 m and a = 0.3 m that are connected by straight segments. The two wires that form the arcs carry unequal currents I = 10 A and I = 15 A. [2.6 x 106 T, into page] P R R
