3. A single infinitely long straight piece of wire carrying a current I is split and bent so that it includes two half circular loops of radius R, as shown in the Figure. If current I, goes through the top loop and current 1₂ through the lower loop (with I = I₁+1₂) and if I₂ = (D/10) I, what is the magnitude of the magnetic field at the center of the circle in terms of I?
