Current density J in the wire = i/(pi*(a^2-a^2/4-a^2/4))=2i/(pi*a^2) Let center of bigger cylinder is (0,0) and centers of two hollow cylinders be (0,a/2) and (0,-a/2) Now assume a wire of radius a containing current density j is centered at (0,0) and two wires of radius a/2 containing density -j are centered at (0,a/2) and (0,-a/2). Now find the resultant field because these three wires at P1 and P2
