11. A solid, cylindrical wire with a radius of 1.0 mm has a current density of 2.7 x 105 A/m². Concentric with this wire is a hollow, cylindrical conductor (inner radius=2.0 mm, outer radius=4.0 mm) with current of 1.0 A but going in the opposite direction of the smaller wire. What is the magnitude of the magnetic field at (a) 0.5 mm and (b) 3.5 mm.
