The figure below shows two concentric circles of current. Find (symbolically) the magnetic field at the center of the loops when the inner radius R coil consists of N loops of wire carrying current I counterclockwise and the outer radius 3R coil consists of 2N loops of wire carrying current I clockwise. (Hint: Use superposition.)
